摘　　要：在海拔5000~5500 m的位置进行施工作业,对现场机械设备存在极大的考验和挑战,尤其对发动机的影响较大。发动机在高原高海拔环境下会出现各种各样的故障。介绍了采取机械增压、定期保养、降尘的方式以提高发动机的进气量,让发动机燃烧充分,排气不会产生高温,从而减少了对发动机的损坏。Construction at the altitude of 5000~5500m brings great challenges to the mechanical equipment on site,especially to the engine.The engine might have a variety of faults in Plateau and high altitude environment.This paper introduces the ways of mechanical supercharging,regular maintenance and dust reduction to increase the intake of engine,so that the engine can burn fully and the exhaust will not in high temperature,thus to reduce the damage to the engine.
