What is the role of the engine timing belt?
The timing belt is also called the timing belt, which is an important part of the engine air distribution system. It is guaranteed to be connected with the crankshaft with a certain transmission ratio to ensure the accuracy of the inlet and exhaust time.
Timing, that is, through the engine timing mechanism, so that each cylinder just to do: the piston just up to the top dead center, the valve just closed, spark plug just ignition.
The timing of the timing belt is to maintain the "synchronous" operation at the moment when the engine is running, the stroke of the piston (up and down movement), the opening and closing of the valve (time)
