The engine timing chain system uses a chain to transfer power from the engine crankshaft to the camshafts, and controls engine timing. Hydraulic tensioners are normally applied to ensure the proper operation of the chain system. Then, it is controlled by hydraulic forces by using engine oil and mechanical force from a spring. Recently, new technologies have been applied to the oil pump of the engine to improve fuel efficiency. The engine oil pump reduced the operating torque of the oil supply through reduced pump capacity, or the variable oil pressure control system was applied to ensure fuel efficiency. However, sometimes, it supplies low oil pressure and low flow rate to the hydraulic tensioner due to the large tensioner piston motion and increasing chain tension. Through this paper, we would like to explain the correlation between the tensioner check valve function and timing system performance. Furthermore, new tensioner check valve specifications will be introduced to improve timing chain system performance. |
