摘要
在对发动机进气歧管中动态波分析的基础上,结合发动机进气歧管压力传感器的动态特性,针对发动机瞬态过程中的空燃比控制问题,提出了MAP动态补偿及基于时间采样的解决对策。
This paper analyzes the dynamic pressure wave in IC engine manifold,and introduces MAP dynamics in both time and frequency domain. The method of dynamic compensation for MAP and time-based sampling are proposed to achieve accurate control for air fuel ratio in engine with speed-density system.
