         PISTONS

This picture shows the basic function of the pistons. Basically when the air and fuel mixture is compressed
it ignites and creates a spark for the spark plug. the crank shaft makes the pistons move up and down and also in a order.

CRANKSHAFT

 Receives oscillating motion from connecting rod and gives a rotary motion to the main shaft.It also drives the camshaft which actuate the valves of the engine.

 Cam Shaft

It takes driving force from crankshaft through gear train or chain and operates the inlet valve as well as exhaust valve with the help of cam followers, push rod and rocker arms.

Inlet Valve & Exhaust Valve

Inlet valve allow the fresh charge of air-fuel mixture to enter the cylinder bore. Exhaust valve permits the burnt gases to escape from the cylinder bore at proper timing.

Carburettor

It converts petrol in fine spray and mixes with air in proper ratio as per requirement of the engine.
