挖掘机发动机低温预热方法的研究与应用
|
摘要
论述了低温环境冷启动对发动机的损害,并提出了液压挖掘机发动机低温启动方案和实施方法。通过对发动机的燃油系统预热和水循环系统预热措施的研究,提出了两种预热方案供不同情况选择,完善了液压挖掘机用发动机的预热装置,通过现场实施进一步验证了研究方案的可行性和有效性。
By discussing the damage to the engine in the low temperature environment, the method of implementing the low temperature start of the excavator engine is put forward. From the perspective of the fuel system preheating of the engine and the preheating measures of the water circulation system, two preheating schemes are proposed for the selection of equipment under different conditions. Improve the excavator engine with the preheating device, providing on-site implementation to further verify the feasibility and effectiveness.
