I Built a New and Improved Explosive Engine with Automatic Timing Systems! (Scrap Mechanic Gameplay) 

remember that transmissions have torque converters to fix the issue with torque

At this point it's starting to sound like an actual engine

Explosive engines are such weird concepts in SM, yet they should be the most normal thing ever.

Should advance the timing. Variable timing can be used so when at low rpm you actually have the explosions delayed, and at higher rpm you can advance the timing (since there is a delay in the explosion). Also, technically speaking from the real world, free moving engines can't do a 1:1 drive and would never be able to move a vehicle without some gear reduction unlike the classic piston engine.

Love the format of showing each step of the design process

Boom Boom engine!!! I think you should gear down since the speed seems excess compared to the lack of torque. Also, you could perhaps try making the engine rotated 90 degrees so the cylinders face forward so regardless of your speed the explosives should still blow ewachother up

You can give the engine more torque by increasing the distance between the conecting rod and the centre of the crankshaft

I think you need a bigger gear ratio...i mean make a bigger gear on wheel axle and smaller on the shaft .. And try to create a v4 engine...maybe that will help with the weight

I think potentially adding a transmission to gear down could help, it also might have to be a slow speed vehicle type of deal

the problem is the differential (the gear shaft) you made with pipes, i think if you just turn the whole engine 90 degree and put the wheels directly in the crankshaft right and left it might work

Maybe work in a transmission type thing where you could engage the drive wheels with a flip of a switch. That way you could gain momentum in both your piston cylinders and at your fly wheel. Maybe gaining that momentum to it's max and then engaging the wheels will be enough to move the vehicle. Or maybe it'll just stall out again lol.

Just an idea for the engine - how about a friction clutch. I.e. the engine spins up then presses a plate on the output shaft onto a corresponding plate on the wheels.

My recommendation is to use your crazy youtuber pull to find someone to code a mod that uses better coordinates for spawning the explosives, i'm sure it can be done. Also, you can try closing in the cylinders to try to prevent them from popping out, or turn off block damage somehow and make the entire thing out of lighter materials except for the pistons also, you;re trying out output a gear ratio of 1:1, try changing that, it might help.

Try to run it in an empty world, though not that noticeable, the physics change a bit at lower frame rates. For example, my rpm tester skips a lot more rotation at lower framerates, and maybe play with the physics slider to see if framerates are more important than physics quality.

Does the explosive go off at top dead center? You may want to consider some ignition timing delay so the bomb goes off after tdc.

My idea would be to work on the timing of the ignition while you're moving. I noticed that sometimes while you used the thrusters to "jumpstart" the engine, you would accidentally start the engine with the wrong timing which caused less power from the explosions to the cylinders. Also, the improper timing of the first ignition possibly created counter-spin that worked against the attempted "jumpstart". Ofc, if you do fix this, you might as well go the full way and make a reverse/braking sequence too.

What you need to do is extend the bit comming of the main shaft adding more torque, or in otherwords give it a bigger stroke but not by just extending the piston out. Also right now you fire sequence would be 1234, instead try 1423, don't know if that would help in a game like this.

Must be the spawner and movement (speed) combination. Like the spudgun when moving very fast. Awesome project, I love it.

You need a clutch my guy. Disengage it from the gear to start the engine, then once the engine is up to speed, engage it to drive. Also, you should have a cylinder going off every 1/4 rotation to keep a more consistent power/rotation. I didn't catch that any of your designs were doing this. I know that's also probably difficult with Scrap Mechanic since you can only build on 90 degree angles while an object is on a lift. I would also look into doing some gear reductions, maybe some sort of gear box. I feel like this is really going to need the extra help from gears no matter how good you get it, or it will just keep stalling out. Also, an electric engine hooked to a bearing on the crank shaft might be good. Set it to a switch or button so you can use it as the starter. Those are my thoughts anyway. Not sure how practical they all are, especially combined together, but I think they'd be good if they're doable in Scrap Mechanic.

try moving the explosive spawners forward in front of the cylinders a couple blocks if theyre trying to spawn where the spawners used to be, just use it to your advantage

Glitch welder has a option to spawn things relative to its position

Try actually getting the cylinders timed to a firing sequence to balance the engine explosions. Maybe it will help with the blown cylinders

Could you make a realistic gun with explosives?

Again going to recommend looking at splob's supercharged V8 in Brick Rigs

I suggest trying out adding in a trasmission, initially inox for testing purposes

This is looking great! You could try and flip the crankshaft 90 degrees so it’s parallel to the car axle. That way you could drive the wheels directly and the explosives would at least not glitch into the side walls while driving.

This video taught me more about how engines work than two and a bit years of studying mechanical engineering

I think you should time the explosion better: they seem very late to me. You could try using a bearing between the crankshaft and the timing wheel to fine tune the delay. Also, direct driving may improve the situation

Hey Kan! So I'm not sure if you realized, but your explosives are detonating about 180 degrees out of time to the piston from when they should fire. They explode when the pistons are at Bottom Dead Center, or slightly off that considering they are maintaining rotation. So I think you're missing out on more engine speed by having the explosives explode so late! I do concede it could be a timing issue in the fact there is a slight delay to the explosion, so maybe the engine is spinning at the max speed already due the the "falling edge" of the explosive time from spawn to explosion being what it is. Anyway, just an observation I had! Maybe adding some sort of explosion timing modulation to adjust the explosion spawn time would help get the engine some more oomph by offsetting that falling edge to allow for an earlier detonation. Maybe use the flywheel rotation speed (almost like a trigger signal on a cam timing sensor) to add in some buffer to control the exact explosion time and make the explosive spawn slightly earlier as the piston speeds up. Of course the issue there is the time to reset the explosive spawners being the big hold up. Your current setup isn't even close to the limit of the spawners' reset time though! The current crank speed seems to be roughly twice the time it takes for the explosive to spawn and then explode, i.e. your explosive spawns at TDC and detonates near BDC ultimately limiting the RPM to half the time it takes for the explosives to detonate. I think this issue may be why the engine has no torque when under load either. It's only getting enough explosive power to maintain its rotation. Using the trigger signal to modulate the explosive spawn timings, you may even be able to add in a rudimentary throttle as well to control the rate of modulation and actually request some engine speed through a modulation setting! To incorporate this, maybe add 4 sets of timers to each bank. Each one with a slightly different time delay. Once the engine begins to fire and run, the timing delay doesn't matter (though realize you would be running each piston in the "past" as you would trigger the timer a full rotation prior to the explosive), but what it allows you to do is shorten the timing throughout the 4 settings. So setting one can be your current timing but set your current trigger to be 180 degrees out (so essentially fire the explosive at BDC, but set the timing to spawn at TDC with the delay), so that way you could essentially spawn the explosive behind TDC and allow it to explode at a faster interval and when the piston is at TDC. So setting 2 could be at 225 degrees (the explosive spawns 45 degrees before the piston is at BDC), setting 3 at 270 degrees, and setting 4 at 315 degrees. 360 degrees would make no sense as the next set of explosives would be spawning at the same time the previous set would be exploding resulting in the explosives to neutralize themselves and seize the motor up. But with those 4 settings, you could essentially support 4 different RPMs which you could request with buttons! So your current motor would be the slowest RPM, but setting 4 would be the theoretical upper limit as any more timing and the explosives would overlap. So your current upper limit would be just under 1 rotation per the time it takes for 1 explosive to detonate after spawning. Right now your engine is running at half that. So you could potentially double your RPM with this modulation stuff! You could even double that again by only firing an explosive once per side instead of at the same side! Essentially turn your motor into a 4 stroke allowing the crank to rotate at double the speed since the piston would be able to cycle twice. Then you could add even more setting and potentially offset your explosive spawn time by up to 675 degrees! So your upper limit would be 2 rotations per the time it takes for one explosive to spawn and then detonate. Just some thoughts on why this ultimately kinda failed! I mean, besides the weird explosive spawning issue lolol

Stellar video as always Kan! One of the ways to get the weight down would be to have modded blocks that have low weight and high durability. Also a mod that creates smaller explosive effects would be nice so that you can actually see the engine without all the smoke and dust.

My tips for improving the engine if you care to: 1. Modpack parts spawner and set the offset based on the velocity of the vehicle. This would be fiddly, but it would deal with the explosives popping out of the engine. 2. Gear mod to gear down the engine so it can give more torque. 3. Would a drag reducer block help at all? My thinking is that, since it reduces the drag, it should reduce some of the strain on the engine?

Nice progress.... So..... I got some ideas.... 1. Use an electic engine as starter, it could possibly make it so much easier to start. 2. Make bigger pistons, not just does it have more momentum, but it can also spin faster as ypu get even more room for spawners. 3 Try easing your engine in for a torque response You need a clutch, one that starts with those shoe thingies rubbing against each other and when you think the engine can handle it, let one side collapse into each other. 4. You need a smaller gear ratio, the wheels spin too fast for the engines' torque.... Maybe that cog mod you once showed could help 5. Maybe you can make a switchable modification: one where 2 spawners per turn per piston injects, for speeding up and one where 4 or more spawners inject per cylinder per turn for the times you need higher forces, like when clutching. Also: You need torque so build it like a torquay engine 6. Try maybe bigger flywheels 7. make the piston rods be in a guide too, to achieve that, build a crosshead engine setup, as the steam engines use. Another idea would be a knuckle rod system or if you don't find anything under that name, google search the picture: Knickpleuel Motor There's a gif to it there. 8. Modded blocks for more durability/less weight and maybe more useful explosives. 9. Say ypur sanity goodbye and reconsider your life choices 10. A gearbox Maybe this'll help

I noticed when the engines were running (at least at high rpms) the detonations were happening basically at bottom dead center which would explain why they wouldn't be giving much torque at speed. since there's probably a delay in the detonation, that same delay would result in a greater rotation angle as the engine goes thru rotations faster. Someone mentioned variable timing as a way to work around this which I think could be a great idea. You could use different color sensors to switch between different settings. As for timing sensors in general, if you put them farther away from the shaft, say on a flywheel, you could get better precision in general since more blocks would pass the sensor in each rotation. That might help the problem in itself, and make variable timing an option if need be. And for building up speed, I don't know how reliable friction between blocks is in SM but some sort of clutch or torque converter system seems like the go to. Some system with two different shafts that try to match each other's speeds. Maybe tires pressed into each other? Idk I'm no expert but I hope some of that helps. Love the content man!

So a couple of notes about this. First off, real engines typically ignite the fuel/air mixture before the cylinder reaches what's called Top Dead Center, or TDC, because it gives the gas mixture additional time to build up heat and energy. In your case this is a very bad thing. Your cylinders need to be well *past* top dead center to not throw a rod when ignited. I'd suggest basically introducing a 1/6th to 1/4th turn delay between the cylinder getting as close as possible to the explosives, and the explosives actually going off. That way the energy can be more effectively translated to the crankshaft rather than trying to shove the piston through the crank directly. The closer the offset portion is to 90 degrees from the cylinder when the explosive goes off, the less strain there will be, although it'll come at the cost of how much energy is recovered from the explosion. Second off, you *really* need to gear this thing down. It's got next to no torque. You can trade torque for speed though, like a tractor. Tractors are slow as hell but could tow God himself out of a ditch if necessary. Real tractors can even flip themselves on their backs if the wheels get locked up somehow. The point is, if you can find a way to make it so you've got a high gear ratio, torque should stop being an issue.

I think you are going to need a transmission to solve the torque problem. Also the timing for a real engine is that the combustions happen when the pistons are at the Top of the cilinder, to get the longest travel. But since in scrap mechanic the explosion is like an impulse, like it happens in one frame, i think the timing should be be when the crankshaft is actually at a 90 degree angle (with the help of a controller maybe) to get the most leverage. And that could also solve the problem of the explosives spawning inside the pistons. I'm not sure if this actually works but these are my thoughts

IT'S A 8 CYLINDER BOXER-ENGINE!!! In a boxer-engine the cylinders are arranged in pairs, with the cylinders of a single pair facing the opposite direction and firing at the same time to cancel out the vibrations. Now, it isn't 100% efficient, but, it does cancel out a large portion of the vibrations. This engine configuration is a real thing, it has been used in some cars since at least the sixties, and most modern cars have a boxer-engine.

You need a very heavy flywheel and a clutch using high friction blocks against the flywheel to try and ease on the power

Actually the coolest scrap mechanic video I’ve ever seen pleaseee do more.

What might be a good idea for the cyclinders is to increase the width of them

amazing! I think the main problems are the timing and initial acceleration. You have set the timers perfectly for a cruise speed, but the acceleration of such a big mass is progressive, so the explosions frequence should ramp up until you reach that cruise speed. Also as Constantine pointed, add mass to all the moving parts to increase their energy. It will though have a slower ramp regarding the previous issue. I hope that can be implemented easily! Hopefully the last of 5 edits or so, I would like to see you play Stationeers! There is nice logic in there as well as many functionalities to be done with it.

"Explosives kill logic" - I can't argue with that 😂

Put engine sideways and attach the wheels Straight to the crankshaft. Gears steal a lot of Energy so this schould give it chances of moving. Remove as much weight as you can! Timing area can be made of wood or even cardboard. If this woud not be enought use modded parts to make this engine really Light. (replace metal 3 with something super Light) :)

Hilarious yet effective, well done good sir

I would recommend two things. Clutch… if it dies the second the wheels are touching, u will never be able to idle, and two, spuds again. Just in case. U don’t need it when it’s still, but if the explosives aren’t detonating, the extra spud could help. I don’t know if u understand rotary engines, but they have an extra delayed spark just to ensure all of it is burned, think of it like that. Also, starter motor maybe in the future? Keep the clutch disengaged and start the engine up, and then turn on the clutch?

you should do this with timers so that if you do it with sensors when the engine stops it can’t keep spinning, but with timers if it stops it continues to generate dynamite and can spin again. thanks for reading. :)

Might I suggest a timing advance system? You wont be able to start with it on, but your explosions seem to be after top dead center

TIMING!!! adjustable ignition timing IS A MUST! use a controller to adjust a mechanical cap and rotor like in points system a few degrees makes the difference with the cylinders leaving the engine on real cars too! if it fires while the piston is still on its way up the hole it will break things, also wire the cylinders with a proper firing order. 180 degrees is fine but alternate the pistons so each opposing one is in the opposite stroke one up one down. then number the cylinders front to back, the left side is 1,2,3,4, and the right is 5,6,7,8 fire them 1-5-4-8-3-7-2-6

If the problem is the explosives spawn point lagging behind the position of the pistons while in motion, then you need to give a buffer to allow for the explosives to spawn slightly behind the spawners. While sitting still it needs to be in the current build setup, but when you start moving those spawners have to be moved to lead their target. You could also just set the engine like an assembly line. The spawner provides explosives that travel to the ignition point that forces a piston to move. The energy is sent to a ratioed gear that allows less load to be applied to the mechanisms functional parts.

I love your content Kan, keep it up❤️

I would try using a gear reduction system for the torque issue, as for the pistons popping out maybe reduce the number of blocks making contact for less friction? IDK. Great vids btw, you're pretty cool!

1) I think the double explosive uses the "equals and opposites" to stabilize it some. 2) A painted square on the fly wheel with a sensor counting bit would tell the rpm. You can use additional blocks to find the max torque outside the movement problem. I love this kind of kANtent and have missed the logic stuff, I can't suggest anything to help with the placement except for building to compensate,(ie; a more complex piston shape so it doesn't calculate a space large enough inside it to place and explosive [++++--- ) but you already had that idea. I dont know how the game would react if you stretch the cylinders to compensate for the placement being behind the cylinder when moving.

Dude, you built a flat 4, that's sick Haven't finished the video yet but the prototype is awesome

You should add a clutch, so you could choose when the engine engages with the wheels.

I love these kinds of engines :D If it doesnt work on a vehicle you could probably build a stationary engine to power something. Maybe a crane or whatever. That would be interesting to see! Also, another idea, if you dont want to use cylidners, would it be possible to build something like a rotary engine or something else that doesnt have to convert linear to circular motion

amazing way to explain how engines actually work.

The one idea i can offer without having tried something like this myself is to maybe try use the games pistons as a kind of guide rails??? but: - Not sure if explosions would be strong enough to compress/extend the pistons far enough (if at all?) - I wouldn't even be able to begin to imagine how you would build the thing with extended pistons - No clue how explosion-proof pistons are either Honestly this is a perfect example of why the game needs some sort of 'telescoping slider' block that copies some properties from pistons (locking movement to a specific axis) while being easier to build with (can be built at diff lengths like vacuum pipes?) and not resisting compression/extension. There's actually a lot of these types of constraints missing, imagine if we had pulleys or ball sockets for example. Could make some crazy stuff with that. I really hope they are going to put a bit of thought into "more complex mechanics" in the future, but considering how development seems to keep pausing & focus is fully on survival now (and not 'more engine features') i doubt its gonna happen :(

You need to advance those sensors. Your ignition isn't occuring until the piston is half way to the bottom of it's travel. As the engine speeds up, it starts pushing backwards on the crankshaft

Today you created a boxer-8! Porsche was just about the only manufacturer to create these back in the can am era

There are engines in real life where the pistons meet in the center and use the same explosion to move them apart, maybe that can help a bit and use the two separate crank shafts for different wheels.

Use bubble block for the logic board and try to use just some strips to reduce weight. Also use a spud gun to eject the thrusters after getting to speed. Try to make the engine as compact as possible to save weight.

you can try and make the cylinders in a kind of v formation even though that is close to impossible from my experiences

If you take a look at a real motor 2 pistons are connected at the same point, but you have them connected 180 degrees apart so when they fire all of your momentum is going into pushing the Pistons in, then you have no momentum pushing them out. If you are to connect them at the same place on the crank shaft one piston will push the other out so it can fire, to send the first piston back out so it can fire, so on and so forth.

If you rotate the engine 90° on the horizontal plane so the cylinders point in the direction of travel The exposives will spawn either just a little inside the piston or a little behind and probbably not spawn on the side of the chamber and glitch out. Maby even make the front cylinders a little longer and the rear ones a little shorter or even delete the rear ones although this boxer engine setup is very ballanced.

As a mechanic, you got a couple things wrong. 1 - Your pistons dont fire at "TDC" (top dead center). Witch is very important cause that is where the most amount of FORCE is. 2 - Your flywheel need to be made out of the heaviest material but only the outer ring. Making it heavy from center to outer of the plat will only make the build harder to function. 3 - Light and low friction for every internal parts and where piston slide. When explosion occur, the thing it push(the piston) has to have minimum restriction of that incoming force. For dual piston setup, just have both connecting rod on the same crankshaft position. One will fire and alternate to the other. If you are missing torque at the end of that, make your "crankshaft connection to connecting rod" farther from the center of the crankshaft. With all of that, hope to see a new video! :)

Kan love this stuff I think the way to stop yeeting cylinders is to fix the ignition timing. The explosion shouldn't go off when the cylinders are fully extended. Maybe try the explosion 5 degrees after the cylinder is fully extended. Hope this helps!

You have to extend the crankshaft arm even more, for more torque. Also your timing seems to be off. I sugest putting sensors on bearing, that will be connected to the controller, and as the engine will accelerate you will turn tha bearing degree by degree until you reach max speed. Unless you do that the engine will just stall again and again

Funnily enough I just finished a compact limited-slip differential design as a project, fits in a 3x3 and runs off a driveshaft. would love to see how that works with this engine powering it!

Couldn't you just gear down the output from the engine where the axel connects? You would lose a lot of speed but you should gain torque assuming SM doesn't have issues with so many collisions

Here’s maybe some ideas: 1. You could put a different gear ratio from the engine to the wheels. Maybe it can’t sustain its momentum because it is too low in rpm for the speed. It does mean it will go with a lower speed, but maybe it is one which it can sustain itself. 2. In stead of fixing opposite cilinders to opposite points on the axle, you could fix them onto the same point and have the explosives alternate. That way per cilinder the time gaps between explosives are shorter en it can maybe run higher rpms. Maybe this will counter the need of a lower speed in idea 1 as well.

"It's 4 cylinders" *gestures to an H8* (Fairly certain the H8 worked without a flywheel since you have to do 180deg rotation for each cycle, meaning in theory the crankshaft would be sitting at 180 every time the second piston bank fired, which in scrap mechanic physics could go either way. An H8 switches this to 90deg meaning just the latent momentum of the driveshaft itself would guarantee it would keep spinning in the same direction). The car won't start without a kick because the back-torque from the wheels is too much for the pistons themselves to overcome directly and work in a cycle. You need a flywheel to smooth this out and potentially literally an electric starter motor (most starter motors slot into a gear to get the engine spinning and then disengage. Obviously in a real car there's also a clutch so you can engage the engine to the wheels gradually instead of all at once, making the instantaneous back-torque lower). The flywheel's momentum is energy storage. You need a certain amount of energy to overcome your inertia. There's a few different ways to look at it. In a real car, the starter motor engages to the engine, spins it a little bit to get the cycle turning (as often it can't reliably kick the flywheel into action on its own). The engine is then slowly meshed to the actual drivetrain at a reduced gear ratio to make the back-torque manageable. Once you've got engine + flywheel spinning reliably, you have a smooth force/torque/power output which makes engagement to wheels a more reliable endeavor. You could probably do it with direct engagement and no clutch, but you'd likely need a gear mod as in vanilla your options for gears are basically n=2 and n=4 which isn't exactly ideal. EDIT: Actually since the number of teeth is irrespective of total gear radius you can't have gears ratios at all in vanilla. Other than doubling up the spars I have no clue how to fix the piston bugging out though, that seems like something the devs would need to work on in order to make the overall engine more friendly to this sort of creation.

Amazing Video! an idea, just cover the pistons, so the pistons cant just jump out. Also, you can use a bearing as a starter motor, instead of thrusters

Try an inline six set vertical Time them 135246 so explosions are not near each other Offset in 60 degree increments based on firing order so 3 should be 60 degrees off 1 and 2 will be 180 degrees You need to adjust gear ratios to overcome torque. With a 1-1 ration you could place the number of explosive used between the vehicle and unmovable wall then the blast would push the vehicle just as far, i imagine 4 dont move that car far.

Last time you made a flat-v-twin, today you made a boxer. Advancing I see!

Move your explosive into the center of the engine to use one explosion to power 2 or 3 pistons (on the same timing). then make the combustion chamber able to trigger any piston in a line backward, that way if it does spawn in later it should spawn on the next piston set, advancing the timing (have it so each next piston is ready to fire if the previous drops the explosive in a further back location see ---> ). next change the timing to hit the piston after its on the outbound stroke, not at the closest distance to the explosion. set a configurable delay on the timing detector, make it seat configurable.

If you need more power you could try compression ignition where the piston itself ignites the explosive by jamming it into the cylinder head. You could also do a similar method of making the cylinder smaller than the explosive so that it ignites instantly. These methods have the advantage of only requiring one spawner per ignition, but they will probably be unreliable and make the engine difficult to start.

What about a thruster starter that doubles as a flywheel? Might improve that janky startup.

gearing lets you have the torque so you don't stall, while letting you travel slowly with a high rpm. so the engine can be running fast enough to not stall, but the vehicle's position change be slow enough to not have the explosives clip.

I would love to see this revisited. Im curious how it would do with a more balanced firing order?

Kan should try this with the dyno and/or the component kit gears and see how it works...

You've made a Boxer Engine. Well done.

since the force is instantaneous, you need to reduce the amount of time where the cylinders aren't being propelled, so a much shorter piston shaft should help with that. In a more recent video you also designed a manual transmission, something that that should help a lot with not being able to start/run on the vehicle.

I think adding more weight to the fly wheel will do to it. You will need to have the wheel off the ground for the start for the momentum to build up and have the weight carry you through the start.

Rotate the engine 90 degrees so that it's transverse. Right now when you're moving forward the "lag" position of the explosives makes them move off center of the pistons which may cause the piston blow outs. If it's transverse, then they will only spawn futher "behind" the vehicle as it moves. While this will still be less than ideal, it should be easier on the engine and you may be able to compensate for it if there is a way to make the pistons move towards the front of the car the faster you get.

The gear ratios are 1:1 so its gonna take more to make it move so maybe put a small drive gear to a bigger axle gear to generate torque then maybe make a transsmision of some sort to shift into a smaller gear to gain your speed but not too small to the point it stalls out

kan: It's such a simple piece of logic... me: Nice flashing lights...😮

Kans computer when he goes to potato mode: wow what just happened I feel great

You gotta hook this up to the dyno

A way to gear it down without changing the gears could be to have the shaft attached to larger connectors to the pistons so a large movement in the shafts is a smaller piston movement possibly with multiple pistons per shaft attachment points. Then it moves slower more efficiently so is more effective. The also have the back raised up with a long front shaft to mean it is able to get ground clearance. This could of course all fail but it could be worth a try

See if you had changed the offset on the crank you would have been running basically a 2 stroke flat 4. An opposing piston engine would have basically the explosives in between 2 cylinders with a crank shaft on each side. They use this for some tank engines and generators, but not for cars., They run off diesel and they are typically 3 cylinders with 4 pistons and they can run very high compression. If you could join the crank shafts together pretty easy then this would cut down on logic and explosives and maybe make the engine smaller. You need a gear reduction in there. Try a wheel with peg sticking out the side that would give you say a 4:1 ratio. The slower speed might fix the spawner issues.

Kan what I’m thinking was to make a gear reduction with the gears mod. That will slow the vehicle down while increasing torque. The lowers speed should help the spawn position problem. I love you kan keep up the amazing videos

Something I'm noticing is the power stroke is having a lag in the Combustion and is putting little torque on the crankshaft and the fact it takes a split second for the explosive to blow up so when the power is applied it is towards the end of the stroke

I've been told to tell you quote: "If he kills the baby waks, Kosmo will unfriend him. Delete him. Report him. Block him. And...probably egg his house."

Definitely need to sacrifice speed for torque. Use the gear mod to do it

Make the cylinders closed to begin with so you dont "blow" pistons and it may be a issue with the ratio that the engine got. Im not a 100 tho and oh btw, try making a 4 stroke engine instead of a 2 stroke, would be fun

Put the spawner on top if the piston and make the crank stroke longer so you have more torque. Time the explosive to go off about 10 to 20 degrees after it passes top dead center. And some kind of clutch system. Like on the first one.

originally i thought the explosive engines were just kind of a meme, but now I can see like piston engines that this has its own niches, that being the most scalable engine in terms of more size getting more power

You should try and have the top of the cylinder head facing the direction you are heading and changing some timing things that could account for the misfires and such

I think the problem is thrust:weight, which is gonna be hard to solve. Not sure if T3 wood is explosion proof - might be. That'd lighten it up. You could sure make the rear platform out of something lighter.

I build very similar. I make a "learning wall" where I do all my concept circuits and concept parts and keep making more wall the more I need lol

@kAN Gaming try putting the thrusters backwards from what I saw your thrusters rotated the crank counter clockwise while your ecu was programmed to only spin clockwise (p.s. I’m now installing scrap mechanic)
