国产旅行车在夏季行驶中容易出现发动机过热现象,这将严重损害发动机使用寿命,过热可导致:1.气缸及进气管道温度过高,吸进的混合气因受热而膨胀,使进入气缸的混合气量减少,导致发动机动力降低,并可能引起混合气自行燃烧,使发动机不能正常工作。2.机油因温度过高而变稀,失去润滑效能,加速机件 Domestic wagon in the summer driving prone to engine overheating, which will seriously damage the engine life, overheating can lead to: 1. Cylinder and intake pipe temperature is too high, the inhalation of the mixture due to heat expansion, so that into the cylinder Reduced gas mixture leads to lower engine power and may cause the mixture to burn itself, rendering the engine inoperable. 2. The oil thinning due to high temperature, loss of lubrication performance, accelerate the parts
