How many kilometers should the timing belt be replaced?
1 Answers
The timing belt should be replaced after driving 60,000 to 80,000 kilometers. The timing belt is a consumable item, and once it breaks, the camshaft will not operate according to the timing, which may cause the valves to collide with the pistons, resulting in severe damage. Therefore, the timing belt must be replaced according to the mileage or time specified by the manufacturer. More related information is as follows: 1. The timing belt is an important part of the engine's valve system. It connects with the crankshaft and ensures the accuracy of intake and exhaust timing through a certain transmission ratio. The timing belt plays a connecting role: the upper part connects to the timing wheel of the engine cylinder head, and the lower part connects to the crankshaft timing wheel. The timing wheel is connected to the camshaft, which has cams that contact small rocker arms. The rocker arms generate pressure through the power transmitted by the timing belt, playing a lifting role. 2. The lifting of the intake valve allows atomized gasoline to enter the cylinder, while the lifting of the exhaust valve allows exhaust gases to exit the cylinder. When the recessed part of the camshaft simultaneously contacts the small rocker arms, both the intake and exhaust valves close, the compression ratio is generated, the distributor ignites, and internal combustion begins, producing power.
