柴油车发动机热保护控制方法研究

Study on the OverHeat Protection of Diesel Engine

文章基于BOSCH发动机管理系统,对柴油车发动机热保护的控制原理、控制逻辑进行分析研究,对过热保护扭矩限值MAP等参数进行调整,确保发动机水温过高时,保护策略能正常作用,有效地避免发动机高温损坏。

Based on the engine management system of BOSCH, the paper analyze the overheat protection control logic of diesel engines. The overheat protection torque limit MAP parameters are adjusted to ensure that the engine temperature is too high, the protection strategy can normal operation, effectively avoid the engine high temperature damage.
