Belts are often replaced on the car's maintenance, but many owners do not understand the car's belt. The belt has generator belt and timing belt.
Generator belt is the most important belt on the car, connecting the generator, air-conditioning compressor, booster pump, idler wheel, tension wheel and crankshaft pulley and so on. Its power source is the crankshaft pulley, the power is provided by the crankshaft rotation, and then drive other parts to run together. When the contact between the belt and the pulley is small, it needs to be replaced. If there is a break, it will cause the generator can not generate electricity, booster pump failure, can not move the direction, this is a very dangerous situation.
The timing belt is connected to the cam and camshaft. The crankshaft connects the piston, which moves up and down when the crankshaft rotates; the cam connects the throttle, which controls the opening and closing of the throttle. The piston and throttle need to work together. When the piston sucks in, the throttle opens; when the piston exhausts, the throttle closes.
If the timing belt breaks, it will make the piston and throttle fit between the problem, and even lead to the piston top bad throttle, and cause damage to the piston, then it is necessary to overhaul the engine. Therefore, it is better to replace the timing belt regularly according to the service life of the maintenance manual.
Now a lot of car's timing belt should use the chain type, the advantage is that its service life is very long, the cost will not break. According to the national standards, general vehicles traveling 60,000 kilometers or two years, it is necessary to replace the generator belt and belt accessories, never used to bad, because once the belt breaks, it will directly affect the safety of driving.
