一、发动机温度过高的后果使油底壳润滑油变稀、变质或烧掉,致使轴瓦与曲轴颈刮伤,烧瓦。两个零件相互摩擦或直线往复运动时,由于零件受热膨胀,破坏原来的配合间隙,出现卡滞现象。并造成起动困难、马力下降。使金属材料的强度降低,甚至烧坏。进气量减少,燃烧不正常。使燃烧室积炭增加,加速磨损,功率下降。 First, the consequences of the engine temperature is too high to make the oil pan oil thinning, deterioration or burn, resulting in crank and crank journal scratches, burning tile. Two parts friction or linear reciprocating motion, the parts due to thermal expansion, destruction of the original with the gap, the phenomenon of snapping. And cause start-up difficulties, horsepower decline. The metal material to reduce the intensity, or even burn out. Intake reduced, the combustion is not normal. Make the combustion chamber coke increase, accelerated wear and tear, power decline.
