配气定时

配气定时对柴油机性能影响的数值模拟分析

Numerical Simulation and Analysis of Influence of Valve Timing on Diesel Engine Performances

研究了不同配气定时以及不同气门升程工质分层程度的变化规律以及影响因素，对自燃着火区域进行了统计分析。

The influence of valve timing on the performance of6106 diesel engine was studied by using GT-Power software in this paper .

全可变气门机构能实现发动机配气定时和气门升程的连续可变，是可变气门技术的发展趋势。

Fully variable valve train may realize continuously variable valve timing and valve lift , and so it represents development trend of variable valve technology .

同时，由于节气门对进气的节流作用，换气过程中的泵气损失明显增加，因此研制一种连续可变配气定时的配气机构，对于发动机节能减排具有十分重要的现实意义。

The technology for the variable valve timing can not only improve the economy and the power of engine , but also reduce engine emissions , so it is valued from beginning .

并通过模拟计算结果和试验结果，讨论空气滤清器、进气管长度和凸轮型线及其配气定时对单缸柴油机充气效η的影响。

Based on the simulated and tested results , the effect of several factors ( length of inlet pipe , air filter , valve cams and valve timing ) on the volumetric efficiency are discussed .

柴油机工作过程的组织，主要取决于进气的状态、压缩比以及由凸轮机构决定的配气定时、喷油压力、喷油定时和喷油模式等参数。

The running property of the diesel engine mainly depends on many factors such as the intake air condition , compression ratio , valve timing , injection pressure , injection timing , and injection pattern , et al .
