基于GT-Power的发动机配气相位优化设计研究

Design and Research on Valve Timing Optimization of Engine Valves based on GT-Power

本文围绕发动机可变配气相位技术展开,依据GT-Power软件对汽油机进行建模。在模型中通过对配气相位角度进行组合,在不同工况下输出不同角度下的汽油机的功率、扭矩、油耗、充量系数参数,进行比较,选择出不同工况下的最优配气相位。

This paper discussed the engine variable valve timing technology and built the gasoline engine modeling basing on GT- Power software. Considering the timing phase angles,we compared the power,torque,fuel consumption and charging coefficient that the engine produced under different conditions and selected the optimal timing phase.
