What is the role of the crankshaft pulley in the car?
This is called timing belt tightening wheel! When tight round as the key function of timing belt drive system, when tight round function is used to adjust the firmness of of timing belt, make the safe and reliable transmission system stability. The timing belt is an important part of the engine distribution system, which ensures the accuracy of incoming and exhaust time by connecting with the crankshaft and with certain transmission ratio. When the engine is running, the piston stroke (up and down movement) of the valve opening and closing (time) order of ignition (time), in the "timing" of the connection, the moment to keep "synchronous" operation.
Right... The most important thing is to drive, the belt is called "timing belt", is used to control the engine, exhaust, the role of the engine intake and exhaust in engine need not I say more......
It is usually divided into the right time pulley (timing belt) and pulley (transmission belt). The timing belt is the opening of the valve in the valve room (i.e., the exhaust). The drive belt is driven by a generator, pump, hydraulic pump, air conditioning compressor.
The crankshaft belt is the power source that drives other engine accessories, driving the generator, pump, pump, compressor and so on.
The pumps, generators, air conditioning pump work, the pump is to guarantee the normal work of the engine water cycle to achieve the cooling effect of generator is for battery charging, guarantee the normal work of the various circuit, air conditioning pump is compressor, used in air conditioning system
