- The timing pulley is an important part of the engine’s air distribution system. It is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust time.
Function:
The function of the timing belt is to link the top and bottom. The upper connection is the timing wheel of the engine cylinder head, the lower connection is the crankshaft timing wheel, and the timing wheel is connected to the camshaft. There is a cam on the camshaft, and its contact point. It is a small rocker arm. The rocker arm generates pressure through the power brought by the timing belt and plays a role of jacking up.
The function of jacking up the intake valve is to let the atomized gasoline enter the cylinder block. When the exhaust valve is jacked up, the exhaust gas is let out of the cylinder block. When the recessed place of the camshaft contacts the small rocker arm at the same time, the intake valve is at this time. , the exhaust valve is closed, the compression ratio is generated, the distributor is fired, and the internal combustion starts and generates power.
