某汽油机VVT系统的优化设计

Optimization Design of VVT System in a Gasoline Engine

发动机可变气门正时技术(VVT,Variable Valve Timing)至今已经有30余年的历史,由于其省油、功升比大等优点,近年来得到了广泛的运用。针对在汽油发动机台架试验运行过程中,某汽油机VVT工作异常进行阐述,对该故障进行分析。通过对VVT系统的优化设计及相关的试验验证,从而有效地解决了故障问题。

The variable valve timing technology of engine that have history beyond 30 years so for. Because of their advantage what is low fuel consumption and high power than the displacement liter in recent years has been widely used. In this paper the gasoline engine bench test is running, a gasoline engine VVT anomaly is expounded, the fault analysis. The optimal design for the VVT system and related test, so as to effectively solve the problem of.
