简介:摘要随着汽车行业不断发展,对汽车发动机的性能要求也越来越高。冷却水泵作为汽车发动系统中必不可少且意义重大的作用装置,其本身质量的好坏,也直接影响着汽车发动系统的工作性能和使用寿命。柴油机水温过高通常会造成散热器内冷却液沸腾、柴油机功率下降、润滑油黏度降低、柴油机零部件间摩擦加剧,甚至会导致柴油机拉缸、汽缸垫烧毁等严重故障。环境温度很高时,当车辆长时间大负荷运转,发动机温度可能超出正常工作范围,如果不对发动机采取保护措施,将会导致发动机过热损坏,发动机舱的热辐射也可能引发线路着火引起火灾。采取发动机热保护控制策略,在保护发动机的同时,也能提醒驾驶员注意观察车辆状态。
简介:摘要:结合汽车发动机的实际特点来看,在分析汽车发动机冷却系统水温过高的原因的基础上,多方面探讨了汽车发动机冷却系统水温过高的诊断方法,并有针对性地分析了发动机水温偏高故障的解决方案,希望对于提升汽车发动机冷却系统性能有所帮助。
