Does the Engine Timing Chain Need to Be Replaced?
1 Answers
Engine timing chains need to be replaced, but not on a regular basis. Replacement should be based on actual conditions—only when there is a malfunction or abnormal noise should it be replaced. If there are no issues, replacement is unnecessary. Here are some relevant details about timing chains: 1. The function of the timing chain is to drive the engine's valve train, controlling the opening and closing times of the intake and exhaust valves to ensure proper air intake and exhaust in the cylinders. 2. The timing chain system consists of components such as gears, chains, and tensioners. Among these, hydraulic tensioners automatically adjust the tension force to maintain consistent chain tightness. This system offers advantages such as compact structure, high power transmission efficiency, and excellent wear resistance.
