拖拉机柴油发动机冷却水的正常温度,除水冷蒸发式的 L195或 S195发动机满负荷或超负荷时允许短时间沸腾外,其余水冷强制式和热流式的发动机,水温均应保持在75～95℃。但蒸发式发动机如水温经常沸腾或强制式和热流式发动机水温超过95℃即称为发动机过热,低于75℃则称为发动机过冷。发动机过热的危害是:燃烧规律破坏,排气冒黑烟,产生积炭,功率下降,油耗上升,甚至拉缸、粘缸、烧
Tractor diesel engine cooling water normal temperature, in addition to water-cooled evaporative L195 or S195 engine at full load or overload allows boiling a short time, the rest of the water-cooled and heat flow of the engine, the water temperature should be maintained at 75 ~ 95 ℃. But the evaporative engine, such as water temperature is often boiling or forced and heat flow engine water temperature exceeds 95 ℃ is called engine overheating, below 75 ℃ is called engine overcooling. Engine overheating hazards are: the destruction of combustion rules, exhaust black smoke, resulting in coke, power loss, fuel consumption rise, and even pull cylinder, stick cylinder, burning
