Abstract

Understanding the velocity response characteristic of the variable valve timing system under parameters of different work status has a very important influence on drawing up the system´s control strategy. In this text, a simulation mold of the WT system has been established based on AMESim. The system changed the engine´s timing phase through turning the camshaft. The simulation results have registered that the speed of the engine and the engine oil pressure have a great influence on Phase-adjuster response characteristic as well as the structure parameters of Phase-adjuster. The engine oil´s temperature and the rotary inertia of rotor were so small that can be ignored. We also got the flow feature of the oil control valve under control signal of different duty ratio.
