For gearing it's better to avoid simple ratios like 100:25 (4:1) as it means the same gear teeth keep encountering each other. It's better to use relatively prime numbers such as 101:23 and then every gear tooth gets to encounter each tooth on the mating gear which promotes better wear.

@gregorymalchuk272 6 лет назад

You need a pressure regulator rather than a simple throttle. You also could use a pressure-balanced inlet valve, formerly used on some steam engines. In order to make it self-starting, you need at least two double-acting cylinders, with the cranks out of phase by 90 degrees, like steam locomotives.

@oldretireddude 6 лет назад

I agree with the pressure regulator. This will allow your current engine design to run on lower pressure and use the extra reservoir pressure to get more run time.

@gregorymalchuk272 6 лет назад

oldvideodude Yes, a given throttle setting at the lever on the rc controller would be the input to a control system to maintain a given air pressure at the engine.

@oldretireddude 6 лет назад

he wants pressure to remain constant. the throttle would control flow only.

@gregorymalchuk272 6 лет назад

oldvideodude Sorry "throttle setting" on the rc controller, but the actual throttle valve itself, that would be modulated by a small PID controller to maintain a given pressure just ahead of the engine. So that a given position of the lever on the rc controller would correspond to a given pressure at the engine, regardless of how full the air bottle is.

@notserpmale03 6 лет назад

The car's momentum is enough of a flywheel. the last thing he needs is even more weight to get it going. The issue is, when the car first launches the motor has to overcome more energy then it can put out. which isn't an issue when it's connected to a small prop, or even on the table. ======THE REST OF THIS COMMENT IS WRITTEN POORLY AND HARD TO UNDERSTAND================= however the ball valve's "resistance" as we'll call it. is proportional to the pressure. And grows exponentially faster than the output, however this for the most part can still be overcome by the power output, until he puts the car on the ground, and the resistance is offset.

@SinhNguyen-rk9gr 6 лет назад

@antoinehezard1315 6 лет назад

I've seen a air powered car design that overcome this problem by having 2 cylinder out of phase (just like a regular car engine), so they drives each other. It was very impressive in term of speed even with low pressure. However that will require some fine tuning with the valves so that they don't work against each other. Nice work btw!

@USWaterRockets 6 лет назад

The car looked like it was going to work amazing in the first test, I did not anticipate the torque issue. I should have guessed because "air hogs" cars had a metal flywheel, which must be there to overcome this problem. Is there a reason you didn't just wrap some rubber bands around the wheels for traction? Plenty of people use them for "tires". They are also great for drive belts, which would have been less work and probably more efficient than the gears. You could probably make a CVT using one as the drive band.

Since we're running "relatively" low rpm's here, I think an arduino combined with a hall effect sensor should be able to electrically open and close the inlet valve of the motor - if you try this, use a trimpot on the arduino's analog in to be able to precisely control the valve timing.

You could also build a simple air regulator on the bottle. That way you can run the engine at around 35psi and pump the bottle up to it's safe maximum psi.

You could also get some glass fiber(sold at retail or autoboty stores) and string to reinforce the bottle allowing it to hold much higher pressures.

On the motor, add a cam pushing a roller and spring. Over the part of the rotation that makes torque, have it store energy in the spring. When the torque is needed to open the inlet value have a sharp down ramp on the cam so the spring adds a large torque just at that point.

You need a pressure regulator. You can only store more gas by compressing it so just add a pressure regulator and maybe a secondary expansion chamber to provide a fixed pressure to your engine.

Cole Smith oohh boxer engine time

@MladenMijatov 5 лет назад

You can probably solve the issue by having a small gear as well as the dedicated flywheel on the crankshaft. This way you will keep the momentum of the flywheel but also keep the gear ratio. There's a reason why old steam engines had a huge flywheel. Also in my opinion, pressure regulator is a must. Plastic bottles can handle huge pressures. They initially bottled with far more CO2 than needed as they loose some of it during transport. For this reason they can easily handle pressures of 150psi.

@evgenkonyshock4913 6 лет назад

You should try using secondary pressure chambers. When piston goes upwards on 2/2 phase, engine releases used air, which still got some pressure and can power smaller cylinder. So in this system you have multiple cylinder engine with only one getting main air input and the rest getting used air pushed from previous chamber on 2/2 phase. This gives a lot more torque and efficiency although decreasing rpm. This system was widely used on coal-steam engines so you should be able to find examples pretty easily. Titanic engine for example has four cylinders with three different pressure levels.

Papooch until your safety valve freezes, blocks with ice, and the bottle explodes. Go watch this video by Ben krasnow to find out what happens when you put co2 through a tiny orifice ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TvmM6qa2a90.html

try powering with dry ice lol

@redsquirrelftw 6 лет назад

I kind of want to see that too. Baby steps though, once it's perfected he can probably try stuff like that after.

@robmckennie4203 6 лет назад

dry ice is a terrible idea. you're just making a dry ice bomb. as counter-intuitive as it sounds, liquid propane would actually be a better solution

@redsquirrelftw 6 лет назад

A small amount probably would not be a big deal. Suppose you'd still want to build a pressure relief valve just in case though. The danger is only if the motor was to seize otherwise the pressure will be lost through the motor running.

@nonowords7857 3 года назад

@@redsquirrelftw you can add a burst value that opens under very high pressure so if the pressure were to somehow build up tooo much, the value will explode letting the air out and the air container won't explode

I personally would suggest attaching a heavy flywheel directly to the engine output shaft. That way you don't have the problem you described where you have to decrease the gear ratio, and you save yourself the problem of having to redesign the entire engine. Then, I'd suggest using a proper pressure regulator for the throttle. That way you can control the throttle more accurately, and you can also pump your air tank to a higher pressure without stalling your engine.

Whyyyyyy not just use a weighted flywheel?

@WarblesOnALot 6 лет назад

G'day, Yay Team ! My thunkin's prezactly...; but I was ponderin' the possibility of usin' the existin' printed Plastic Driving-Gear/Featherweight Flywheel to make a Plaster Mould, then melt or burn out the Plastic (as is done with Lost-Wax Casting) and then cast a Metal Gear...; but, of course y're right, simply glueing a small Coin or a Steel/Lead Washer onto the Gear would cure the problem, with a shitpotful less mucking around... Have a good one, ;-p Ciao !

@geniusaur 6 лет назад

WarblesOnALot tbh I was thinking to just turn a Brass or steel weight, being an aerospace engineer he should have access to a lathe XD

@simontillson482 6 лет назад

I agree with everyone else who says add a flywheel. That's how you solve the conundrum, by adding mass to it, so it can operate the valve at higher pressure. Most efficient solution is probably to put a shallow circular channel into the big gear, and put a large metal washer in it. A solid disc would be wasteful, since the central part just adds mass and very little rotational inertia (check out the flywheel design on a traction engine for example). It's an elegant project, this one, I'm looking forward to seeing how it develops.

@jtsiomb 5 лет назад

In a car, as opposed to a plane, you probably want to be able to actually stop and start again. You need some kind of cluch mechanism to keep the engine running at a low throttle setting always (with its own flywheel), and only engage the drive train when you throttle up. A centrifugal clutch would be interesting to 3D print, and wouldn't require a separate control.

Lol this definitely showcases what you were talking about in the other video, the need but complication of adding a pressure regulator.

Make 4 wheel drive with 4 engine

@modwannabeminecraft1246 6 лет назад

u Bundi if you end up having for engines you end up using more air which means more tanks which means more weight and on top of that if two or more of the engines fail to make a revolution the car would either go in circles or keep going straight uncontrollably plus this would alleviate having any steering control unless you make it into a six wheeler which would make it very difficult to make turns nice idea though.

@mandernachluca3774 6 лет назад

@laharl2k 6 лет назад

Modwannabe Minecraft No problem, just use a 4500 psi scuba tank. It should compensate fot its weight

@modwannabeminecraft1246 6 лет назад

still to heavy XD in that case the car would have to be tethered sadly :( nice idea though :)

@robmckennie4203 6 лет назад

I don't know about that, but there's certainly no replacement for an m60 in the trunk

@lucasannio9320 6 лет назад

Forever13 pt rotary air engine? Lol

@vladimirlucifer4566 6 лет назад

Boosted Rc’s Not talking about this. And no. I actually designed some hydro rotary years ago, since I make hydro engine concepts, but I can't really patent them. And, I'm thinking about the most efficient engine right now. I'm not kidding, I actually use hho for my concepts, so I'm still a bit different than them. And yeah, I always thought about Hydrogen combustion engines. No pollution at all. It's great. But the Mazdas hydro system is not quite the best. Hopefully they improve it.
