摘要
In modem four-stroke engine technology, variable valve timing and lift control offers potential benefits for making a high-performance engine. A novel electro-hydraulic fully variable valve train for four-stroke automotive engines is introduced. The construction of the nonlinear mathematic model of the valve train system and its dynamic analysis are also presented. Experimental and simulation results show that the novel electro-hydraulic valve train can achieve fully variable valve timing and lift control. Consequently the engine performance on different loads and speeds will be significantly increased. The technology also permits the elimination of the traditional throttle valve in the gasoline engines and increases engine design flexibility.
在现代四击的引擎技术，可变阀门预定和电梯控制提议潜力为做一台高效的引擎受益。去四击的汽车的引擎的一列新奇电镀物品水力的充分可变的阀门火车被介绍。阀门火车系统和它的动态分析的非线性的数学模型的构造也被介绍。试验性并且模拟结果证明新奇电镀物品水力的阀门火车能完成充分可变的阀门预定和电梯控制。因而，不同负担和速度上的引擎表演将显著地被增加。技术也允许消除传统在汽油引擎和增加引擎设计灵活性扼杀阀门。
