Wuling kindergarten school bus,Air enters the engine through the air cleaner and proceeds to the throttle plate.You control the amount of air that passes through the throtle plate and into the engine with the gas pedal.lt is then distributed through a series of passages called the intake manifold,to each cylinder. At some point after the air cleaner,depending on te engine,fuel is added to the air-stream by either a fuel injection system or,in older vehicls,by the carburetor.

Wuling kindergarten school bus ce the fuel is vaporized into the air stream,the mixture is drawn into each clinder as that cylinder begins its intake stroke .when the piston reaches the bottom of the cylinder, the  intake valve closes and the piston begins moving up in the cylinder compressing the charge. when the piston reaches the top ,the spark plug ignites the fuel-air mixtur causing  a powerful expansion of the gas,which pushes the piston back down with great force against the crankshaft,just like a bicycle rider pushing a gainst the pedals to make the bike go .

Since the same process occurs in each cylinder we will take a look at one cylinder to see how the four stroke process works .

The four strkes are intake ,compression,power and exhaust.the piston travels down on the lntake stroke ,up on the Compression stroke ,down on the Power stroke and up on the Exhaust stroke.
