An engine timing chain system uses a chain to transfer power to the engine crankshaft and camshafts, and control engine timing. The chain is divided into three types, namely, the Silent, Roller, and Bush chains, applying to different types of engines, depending on engine characteristics. Related parts are made with high precision to ensure proper durability and function in high temperatures and vibration engine environments. Roller chains are mainly applied to gasoline direct injection and turbocharged engines due to their good wear performance and efficiency. However, an abnormal noise issue occurred on a gasoline engine, in which the roller chain is applied. The issue was resolved by analyzing the return hardware and the conduction of tests. Through this paper, we would like to explain the effect of improved noise performance based on design and the change in the assembling process, and confirmed the results by analyzing the results of the experiment.
