Finally more pneumatic stuff! This is what I came here for. A second cylinder would be nice, you could make the rear sprocket larger for torque. It would make it easier to move if you started by pedaling and let the engine take over - there's probably not much to get the bike moving on its own but you could probably get it going and maintain a speed with the cylinder. Any chance we could get the Arduino project code? Also, one final note, a hall effect sensor would be better. Infrared can easily pick up interference, especially outside. There's plenty of television remotes and garage door openers out there waiting to screw up your timing, discounting the IR coming from the sun and street lamps!
@AiOinc1 5 років тому
@Farley Moab Interrupt driven would be better I think, that way you could do something else in the background when not updating the valve positions. Check sensors, calculate efficiency, diagnostics, etc
@handsup90 5 років тому
Yes! Hall effect sensors are far more reliable than IR sensor or mechanical switch. Especially in sunlight, an IR sensor gives a lot of false positives. Also a simple motor encoder unit attached to the sprocket wheel can give lot more precise information for triggering the relays

I actually made an engine quite similar to this a couple years ago but with 4 pistons instead of 1 (vid on my channel). I found one of the most important things is to advance the timing as the rpm increases and to gear down the output as currently your engine seems to be struggling to get past top dead center. Nevertheless I'm very excited to see where this goes in the future and wish you the best of luck.
@tananam9782 4 роки тому
Reciprocating internal combustion engines are basically air pumps, very similar in concept (Look at very early motorcycles, and they will seem oddly similar to this bike). They operate on a similar principle. Gasoline engines require variable ignition timing dependent on engine speed (it takes time for the fuel to burn, so the process has to be anticipated before the piston is in the ideal position). Similarly, I expect delays in air flow into and through the pneumatic cylinder will also have to be anticipated. Good comment.

@RoboTekno 5 років тому
This is so awesome. I would recommend you calculate your required torque to achieve the acceleration/speed you want. You should be able to back calculate through the wheel, sprocket ratios, and eventually to your cylinder and find how much punch you need at the piston. You then can calculate your required piston size too. You can get your required 'thrust' force by having someone pull yourself on your bike with a scale. Whatever force you measure parallel with the ground is the same force needed at the contact patch of the wheel; and again back calculate through all the gears. That should get you your required torque and piston size too. Keep us posted on this project. It would be so fun to this turn into a steam engine bike one day too :-D

Love the air-engine video's! Just thinking out loud, I'd expect there to be a trade-off between torque and efficiency, which is also influenced by cilinder volume. In order to end up with a one atmosphere pressure at the end stroke the pressure going in must be reduced, reducing the torque of the cilinder. This problem can be omitted by adding cilinders, or by using a larger cilinder, either way increasing the (sum) cilinder volume.

Friggin genius, Sire! YT was running in the background and I was like "what's this noise like a tiny steam engine" I bet the tank is heavy, but what if you made a composite monobody bike frame with walls thick enough to endure pressure? Less components, fitting, and more stable mounting for the piston.

So far you've done a good work ! Some improvements may make it excellent: A stronger but LONGER pedal for a bigger moment, and a faster back wheel by using a suitable couple of gears.l.

How much potential energy is actually stored in the compressed air reservoir?
@charlesthompson8704 5 років тому
101.3 J/L*atm. He said 100 psi, and it looks to be around 10 L. So a little under 7 kJ. Or about the same energy as 0.16 g of gasoline. The energy density is roughly 64,000 times less than with gasoline.
@MrDomino4ever 5 років тому
The energy is pressure times volume. The pressure is 100psi = 690kPa. I don't think he said how large the tank is but I'd guess it's around 30 liters. So 690000Pa * 0,03m^3 = 20700J. For comparison that's about half of what the battery of a new smartphone can store.
@mollymillions5438 5 років тому
@@MrDomino4ever That's what I was thinking (not a whole lot). Not saying I hate the video though, I understand that he just wants to test the concept. Cheers.
@tin2001 5 років тому
The benefit of air is it can be done without dangerous substances or specialised metals. Steel or aluminium will do. Of course the downside is the usable range is about the same as the early rubbish electric cars.

@jacksoncheng3070 2 роки тому
In my mind I thought pedaling was going to compress air into the cylinder, and then you would release the air for a rocket boost.

In principle excellent idea I can see a lot of potential with some tweaking.it definitely works just need to engineer a way to fit more pistons and to increase the capacity of the compressed air but on the whole I'm very impressed ! well done keep going

@xSchattenfluchx 5 років тому
Much more reliable at least, maybe not more accurate
@AiOinc1 5 років тому
Yes, a hall effect sensor would almost certainly be more reliable and accurate. Infrared gets interference from daylight.
@MyTubeSVp 5 років тому
His system allows for much more precise valve control. The 1/rotation reset function compensates for pulse drops that will surely occur in an ir based system.

*Tom Stanton* Clicked on this so fast! Very interesting video and subject. Being interested in inventions I have always said that when compressed air motors have a breakthrough in technology (above 5-10% efficiency) it will literally change the world. Or the military will sieze the patent, if they haven't already that is. Compressed air storage for energy generating purposes mated with actually efficient air motors is the breakthrough this world needs, it would make batteries and other storage technology obsolete in many cases, especially for solar and wind storage. Thanks again for an excellent video!

Great stuff and it's only a couple of modifications away from a clown bike active frame too! I wonder if the valve system could be tweeked so that it can be recharged by using it more like an exercise bike on a treadmill or by grabbing on to passing cars!

The pneumatic control valves already exist, Ingersoll used them for decades, you get all the components you would Have in a electronic circuits. I always enjoyed how they mirrored each other.

@bobosims1848 Рік тому
Hey Tom. I was thinking, you should try to pedal normally up to like 4m/s and THEN see if/how the system keeps up. Don't immediately expect it to handle acceleration for you, but try if it will MAINTAIN a normal speed if you speed it up to that yourself. Of course, I'm three years late, so my tip won't do much. Oh well, what is a man to do, time travel? Sorry, my air pressure is too low for that .
