    with : PV = nRT In 2 liters at 4 bars, there is 9.5*10^(-3) mol If you want the same quantity of material but in 200 ml ( like in a aerosol can ) you need a pressure of 39 bars. Good luck, and be careful

    To have an idea of "how long it will last" I can give you my experience. I have a compressor with a 2L Bottle, at 4 bar, with my V4, at full throttle, it last about 30 seconds, if I reduce the pressure at 1 bar to the engine, it can last 2 min, but at 1 bar there is not enough power to do somthing. And I want to say that this engine is one of the best I have ever made, it's not leaking, the pistons and the switches are exellent, this engine is very efficient. (I m sorry, I m not very good in english so....)

    But it's very hard an dangerous to use, because it's about 40bars. And even if it works, it would only be for a few minutes maybe. For me the best solution seems to be the pneumatic hoze.

    I made a very powerfull and small v4 engine. I want to show you the result, tell me what you think of it.
