@andrewbthomson indirect injection is when theres a small chamber in the cylinder head were the fuel is injected , usualy the end of the glow plug is in this as well :-)
@MrSethious its direct injection if thats what you mean, (maby called direct combustion in america?) a non direct injected engine injects fuel into the inlet manifold, as you can see the fuel is injected streight into the cylender in this vid. there are many advantages to direct injection, it gives you a much more controllable burn.
@woodscritter No, this is obviously a four-stroke engine.. 2-stroke cycle is completed in ONE revolution. Combustion of fuel and compression of air take place at the same time. The engine above makes TWO revolutions, one for compressing air and another one for fuel combustion. Start over your studies.
@Frederik19951995 no, crankcases have an overflow through which expanded gases escape when the air in it heats up, any air that's being sucked in can be blown out as well ;)
@Frederik19951995 . Yes but when a piston goes up to create a vacuum, another is going dawn, canceling that vacuum. Even so, on some motorbikes with one piston, they are running, don't they?! The heat cause by the engine makes the air expand, and many others things canceling that piston effect. Probably i am wrong.
@Frederik19951995 there is usualy a pipe leading to the inlet manifold , mostly they r on the rocker cover :-)

let me ask something... its direct combution?

I have a question: What about the vacuum in the crankase, when the piston moves up??
vaccum in crankase = Makes it difficult for the piston moveing up ?? Am i wrong?

They make both.
