摘要
文章对缸内直喷废气涡轮增压发动机的排温保护控制策略进行了研究,通过降低空燃比控制的基础上增加扭矩模块控制,解决超温保护问题。通过道路及NEDC循环测试,表明排温保护功能对发动机性能影响较小,可以有效的降低发动机热负荷。
The exhaust temperature protection control strategy was studied on a turbocharged gasoline injection engine.Increasing torque module control based on reduction of air-fuel ratio control.In order to solve the over temperature protection.Through the road and NEDC cycle test.It shows that engine performance is less affected by temperature protection,but it can effectively reduce the Engine thermal load.
