Is an Electric V8 Engine a Good Idea? 

Can’t wait for that video! Always wanted to know how a Tesla works beyond the standard electric motor!

I would challenge one comment that you made about ICEs which is a very commonly held misconception.... In a typical automobile the peak efficiency of the ICE is typically about 35% however the average efficiency based on how you actually use them will be much lower than this. With such low efficiency many people wrongly assume the translation from a linear to rotation motion must surely be a major contributing loss and this wrong assumption has been the starting assumption for a plethora of very complex alternative ICE designs. If you do the analysis it turns out that the actual mechanical loss in converting the linear to rotational motion is less than 1% hence you can't use it as an argument for explaining why you typically get less than 20% efficiency from your dinosaur burner under the hood of your car.

@@michaelharrison1093 Very interesting. I’d like to see that analysis if you have a source! Also besides efficiency you can realize a lot of other problems with having to convert linear motion into rotational. It necessarily requires a lot of moving parts. So I think the efficiency is only part of the problem.

@@TheActionLab hey man I want you to know I've been subbed to you since you had about 200k subs and your videos are amazing, thank you for them!

What I know that Tesla S model used Induction then they use Permanent Magnet and now using hybrid of PM and Reluctnace motor which is IMSynRM

Watching RU-vid is not either, but enjoyment is important too.

@@JiltedValkyrie 😂

No. The only relation this has to a gas engine is that it shows pistons go up & down. There is so much more going on with the pistons alone (let alone the rest of the engine) that isn't shown that makes this demonstration about as useful as using a kite to explain an airplane. Cool toy though.

@@JiltedValkyrie it depends greatly on your goal, RU-vid can often be a relatively good source for entry level instructional material for most subjects if you know the right keywords.

There are small model sets that use an electric motor. Basically a starter motor to turn the crank and everything realistically. There pretty cool and don’t need fuel

Well nice engineering but not practical. But maybe it has an element to it? I think he forgot to mention this. Magnets lose their magnetism overtime but electric magnet? I think that's a great idea just like the Maglev. Electric Magnet + Engine Design = great source of power. Of course it's not perpetual but it can run very much that long. Action Lab did a great job in making the model of this!

I think that having an electric engine would be an incredible accomplishment for the automotive industry because of a certain type of people that EVs do not impress: Car Enthusiasts. while many would say that car enthusiasts will always love the latest stuff, they don't, they would much rather hold on to the legacy that the automotive industry has made (specifically with an engine method, not electric motors), and I think that if there was a car out there with an electric engine, the Car Community would appreciate it much more since it does its best to be what they see as part of the legacy of cars.

Do keep in mind that not all enthusiasts think that EVs are dumb, I'm just saying that they don't prefer EVs to Gas Cars.

... but you could retrofit a petrol engine with this idea😁👍

​@@claytonj2024 I don't see how this would help. It would make it unnecessarily complex, still probably wouldn't match up well with a manual gearbox, and even if it did, the performance you get out of it would almost certainly be well below what you get from a conventional motor attached to a single speed gearbox

Exactly, More noise less efficient and overley mechanically complex.

​@@dogwalker666 hence fulfilling the basic requirements of American muscle cars

@@DFPercush never heard of it. Is it good?

@@nugboy420 just type it in the search bar, dude made an engine simulator

@@DFPercush thanks I’ll do that now I’m still up and need something to settle down and fall asleep lol.

@@DFPercush I did check it out btw. And yesss

Cool Idea bro.

Wouldn’t that slow the crankshaft or skew the timing of the engine?

@@TheNuclearBolton It would work if you fired 4 of the 8 pistons at the same time like in that model. That way while half the pistons are being pulled to the top, the others are being pushed down at the same time. However like he said you don’t usually want to fire multiple pistons at the same time.

boys have penis and girls have vagina

pffft. how typical. how imaginative. how about making the piston from an iron slug, place the coil at the midway point, wrap a single copper ring around the piston, then simply slam some power through the coil when the slug is in the middle, so the crank is at 90 degrees, with maximum torque, and the induced current in the copper ring causes a repulsion that forces the piston down? and up on the return stroke. and you can also have coils top and bottom to fill in the other two half strokes. attraction sucks. repulsion kicks arse. then the return spike of the collapsing magnetic field from the coil being de-energised can be captured into a capacitor and recycled, but thats silly talk.

If you look at the LEDs in slow motion, you can see they alternate. They are being reversed.

Still wasted energy, electric stuff just needs an ESC this is just wasting effort where and engine produces mechanical energy from chemical energy.

@@osmacar5331 in that too energy gets wasted as heat

@@sdspivey no those are there to show what the valves would be doing in a real gasoline engine

@@osmacar5331 Dude it's a proof of concept video. He's not trying to revolutionize the engine, he's showing a cool scientific design and explaining why it's inefficient.

Im pretty sure that you can add a transmission straight to a electric motor. They don't do it because now everyone uses automatic transmission. I would LOVE a manual electric car.

@@agoogleuser2619 Not everyone. Maybe in the usa. But there are many other countries around the world where that isn't a problem to shift gears.

@@gergonagy3679nah not in the usa bro theres alot of manual drivers here

The oil companies would have your head.

Why?

I aint heard that name in a while. My school was passing them out during my time there for arduinos.

Looked more like a kit, although if he did build it himself, that would say a lot. *I just checked the description and it has a link to the kit that you can buy.

@@MyHandleIsGood I just think that would be the coolest thing to build - for real. Like start with a real lightweight aluminum block V8 engine (from a wreck or wherever), and rebuild the cylinder heads just like in this little plastic kit. You would have to custom machine "pistons" from big huge magnetic blocks of material, and probably sleeve the heads with teflon sleeves or something else really slippery. I just wonder how well that would work, and what kind of power it would consume and what kind of power/torque you could get out of it. Hmmm....

I didn't build it. I put the link in the description where I bought it. It would be very cool to build a more powerful version of this one

@@deanlawson6880 you could easily exceed the maximum tourqe of the original engine. Very very easily.

@@TheActionLab my cousin is 15 and interested in this tech. Do you have a similar Action Lab kit?

@Edward Elizabeth Hitler You're welcome and my pleasure honestly. It is the most beautiful place filled with more kind and friendly people that I have seen on Earth so far. I literally cried when it was time to leave.

Power is limited by amps × coil resistance / period of time to dissipate watts of heat. Powering on the push and pull has current flowing through the coils twice as long reducing the max current to 1/2 of where one has current flowing half the time at twice the current. Just saying one can get the same max power using 1/2 a cycle And doing power on 1/2 a cycle allow one to use cheap steal piston rather than expensive temperature sensitive magnets that loose their magnetic strength over time.

While one LED could be directly powered, the other one might be lit using the movement of the magnet in the solenoid via inductance alone. It would create a more powerful engine to both push and pull the magnet, but I think it was an attempt to be as similar to a combustion engine as possible by having only one powered portion of the cycle.

@@Tsudico I believe that you are right. I think that one LED is showing the switch off due to induction of the magnet. I think it only has one powered portion according to the short description from the manufacturer.

And have like a a few hp car? And add a few thousand pounds of batteries lmao Its not at all a possibility if you didn't know

Well, the other way around, if you have a communal crankshaft of X length, the public can add/subtract modular motors to use it's energy and/or dynamos to add to it's momentum, like energy buyback for electric vehicle parking lots or whatnot

Because there aren't actually any losses due to that

@@giovanniquargentan6198 Except there are because the connecting rod is the same length throughout its movement. When it hits 90 degrees, the piston has traveled about 55% of the way down the bore, rather than 50%. This causes uneven forces throughout the movement of the piston, the piston moves faster in the first half of the stroke than the second half. This is secondary engine imbalance. And the connecting rod is stealing power from the crankshaft, from the other pistons, to do this in both halves to make up for those imbalanced forces. The engine is vibrating rather than delivering force to the wheels, which is energy loss. Balancing shafts can be used to reduce this imbalance, but it's a treatment to overall engine vibration, not a cure to the root issue, and does nothing to treat vibrations experienced by the crankshaft itself. You have to fix the connecting rod to fix this inefficiency.

@@KaiserTom Thanks. Very interesting information there. I would love to learn more about this.

@@KaiserTom you are correct, there are some losses in vibration, BUT they are very very minimal. I suggest you check the replies under the pinned comment of action lab, i gave a much more detailed explanation, also there's a guy named "michael harrison" who also explained it correctly.

@@HeyChickens check out the channel "driving 4 answers", he's a nice guy who knows what he's talking about

You should definitely make videos

@Edward Elizabeth Hitler granted mine was a bit different. Custom head with eltromagnets inplace of valves. Once the distributor lit up the magnet it pulled up on the piston which had a fixed magnet. By sending current thru two magnets on the head I could push pull the pistons. By putting in a potentiometer I could controll the force of the magnets.

Where you able to hook an alternator and a battery to it?

I mean if you could do something like that and reduce the overall force required to push the pistons you could get higher rpms with same amount of wear maybe more of a race thing then an efficiency thing

Actually we can use this configuration to assist internal combustion engine meaning boosting the overall power of the engine without much issue and for the same volume of engine

This is all very impossible sounding. The magnets on the piston will get demagnetized in the extreme environment, and considering the cylinder is metal, the magnetic fields won't even go through to the other side to energize the coils. The best way to go about this would be to attach an electric motor to the engine output shaft through a clutch and using it as a motor/alternator as needed. In other words, a regular hybrid car.

@@kamisama9715 one. why are there magnets anyway. two, i use ferrite magnets to hold tungsten carbide tips as i braze them. they get red hot and stay magnetic. three. why magnets again? last time i looked inside an induction motor, i found zero magnets. thing is... this whole video, this comment thread, these replies... are an example of stuck in the rut thinking. complete misunderstanding of how basic machinery that powers our everyday lives actually works. complete inability to look at things from a new angle a different perspective. i can get a 50mm ferrite slug to repel from a coil with 10A at 12v. it can create 12T of pressure. i use no MAGNETS. i tried figuring out gauss and webers and oesterd once but wow, that stuff just makes it all seem confusing and obscures the simplicity... its for professors to teach, not for people to actually understand and use in practical things. there is no easy way to correlate "so many turns of wire at so many amperes makes a field this strong that can lift so many kg of a ferrous material". its all obfuscated and made ridiculously complex. easier to just fiddle with bits of wire and some logic and use a strain gauge. how much pressure can you get onto a crankpin with a traditional combustion event in a piston engine, with a 50mm piston? take 100bar to be the maximum pressure available, at TDC, when the crank cant really do much... and remember, thast only a brief spike, its well below that by half stroke... so how much torque could i get with my 12T on the same crankpin? when its at 90 degrees rather than TDC? and i can dump that power pretty fast... and it comes back when i turn the coil off!

@@whatnut every combustionable engine can run off of hydrogen. I'm talking about using 1880s technology also. No spacecraft, just ancient primitive science

@@banditeastlick2471 no thanks. If it comes down to it I'm going to go to the local junkyard and grab as many old tires I can, heat those babies up to about 800 Degrees and convert them to fuel oil through pyrolysis, then I thank you distill that oil at about 160 to 200° Celsius and it vaporizes all the hydrocarbons into a fine liquid AKA combustible fuel that can run a gas engine. You would have to add a little bit of the fuel oil to the distilled mixture to up the octane for a gas motor. I've seen them doing this in Rwanda, they literally distill gasoline and Diesel using old tires, all that's left is the steel built from the tire and ash.

@@ericbeltrami2718 when the SHTF do you really think you will make it with the footprint that will create? I will send you to a link to hippie that will show you how easy it is to run off of hydrogen. It's buried in my "truth is freedom" playlist

@@banditeastlick2471 Hydrogen? not without reprograming the computer to handle the change in fuel density and refitting the fuel injectors. Ethanol would be an easier replacement.

I see very few moving parts.

@@moabman6803 (piston (plus 3 rings), arm, crank)x8+2 bearings. Technically this would be fewer moving parts as you don't need camshafts, I think you can reduce the coolant flow with this design, but you'd still need oil flow. no need for a fuel pump...

only benefit i can think of is the power/size ratio which isnt even that much better V engines are super cool tho lol

@@falkez1514: Nope, because the power/size ratio is already MUCH better with just a standard motor, doii. But yeah, this is cool as just some kind of novelty thing.

UPDATE to my OP: Yep, my guess was right; there is no benefit of this over purely rotational motors. Otherwise they probably would've been in development already.

Problem is that you'd have to have a super short stroke because the range of magnetic force drops really quickly.

You can just pull the ”pistons” away from the crankshaft.

I find it ironic that petrolheads downplay EVs to mere toys only for them to cry about them not having sound they wanna hear right after.

Not whatsoever.

Its a cool idea, and an idea many of us have thought about. But its really a gimmick. Plus, itd be orders of magnitude simpler and easier to bolt a regular motor to a transmission

Why is it not a good idea?

It's basically a waste of energy

@@Alasswolf Why? Solenoid motors can be very efficient

@@stellospace what really matters is that you'll be able to feel the performance.

Accelerator pedal position, engine speed, and engine load all effect the sound. Not just pedal. But these things are all simple to monitor and implement. Hard part is to make it sound right and be loud enough to be realistic and still fit comfortably in a car.

@@ninefingerdeathgrip Absolutely. I think it'll come soon if it has demand

Cars don't actually sound like cars. Modern internal combustion engines are very efficient (well, as efficient as a linear-to-rotational conversion of discrete explosions can be) and don't make much sound. Not only does this displease people who like old-fashioned engine noise, it is unsafe for pedestrians who can't hear a quiet car coming. Manufacturers use all sorts of systems to make cars noisy again, and "just play engine noises over a speaker" has been a popular solution for several decades now. The field is called "Active Sound Design" if you want to know more.

The oil would last a very very long time because there are no combustion gasses. This is actually a great idea.

Would be easier to just bolt on an electric motor between the engine and transmission. Honda's old hybrid IMA tech used to spin up the engine using an electric motor for added torque.
