“…In design area, some scholars improved the timing chain system performance by optimizing the parts or analyzing the dynamics characteristics. Jung et al 11 and Park et al 12 optimized the tensioner arm in the timing silent chain system by integrated approach which contains the dynamic and structural analysis as well as the topological analysis, and researched the influence of the initial tension of the timing chain system on the transmission effort. Joe and Young 13 studied the effect of the high flow check valve in hydraulic tensioner on the timing chain system performance.…”

More and more unconventional timing silent chain systems are used in the low-emission vehicles or hybrid vehicles, but engineering practices show that the classical design method cannot ensure the stability and the feasibility anymore. According to the angular velocity fluctuations of crankshaft, the maximum accumulation length is calculated to design the ideal path of the tension side chain. The tension rate is defined to determine the ideal chain path at the loose side. In order to match the ideal chain paths with the actual chain length, the pitch variation algorithm is proposed. Based on a specific inline engine, the unconventional timing silent chain system is designed by the classical design method and the new design method respectively. The design process proves that the new method is belonging to a real parametric design, and it can expediently and quickly obtain the results. With the dynamics simulation comparison, the results show that the operation performance of the unconventional timing system can be roundly and significantly improved by using the new design method. Furtherly, this new design method is not only suitable for the unconventional timing system, but also suitable for the other types of timing systems.
