摘要
提出一种新型的四冲程发动机液压可变配气机构。建立系统非线性数学模型,并分析配气机构的动态特性。仿真和试验结果表明,新的液压配气机构能实现可变气门正时及开度的控制,可适用于高转速发动机,具有一定的实用性。
A novel electro-hydraulic fully variable valve train for four-stroke engines is proposed. The nonlinear mathematic model for the valve train system is set up and its dynamic characteristics are analyzed. Simulation and test results show that the novel electro-hydraulic valve train can achieve fully variable valve timing and lift control. Consequently the engine performance at different loads and speeds will be significantly enhanced.
