误区一 柴油牌号越高越好。柴油牌号的选择是以保证在最低气温下不致凝固为原则。为更好地发挥柴油机性能,必须使柴油的凝固点低于气温5℃左右,不能认为牌号越高越好,否则将影响柴油机运转。 误区二 机油越多越好。机油不足会发生烧瓦事故,但机油过多会使发动机工作时曲柄连杆剧烈搅动机油,不仅造成柴油机功率内耗增加,机油消耗过大,而且还会发生燃烧机油现象,造成气缸积炭,排放污染增加。 误区三 机温越低越好。有的机手为防止机体温度过高,拆去调温器来强行降低机温。若机 Misunderstanding a higher grade diesel better. The choice of diesel grade is based on the principle of guaranteeing that it will not solidify at the lowest temperature. In order to give better play to the performance of diesel engine, the freezing point of diesel oil must be lower than the temperature of about 5 ℃, can not be considered as high as possible, otherwise it will affect the diesel engine operation. Misunderstanding two more oil the better. Insufficient oil will occur tile accident, but too much oil will make the engine crank crank vigorously stirring oil, not only caused by diesel engine power consumption increase, excessive oil consumption, but also the phenomenon of burning oil, resulting in cylinder coke, emissions Pollution increases. Mistakes three machine temperature lower the better. Some hands to prevent the body temperature is too high, remove the thermostat to force lower machine temperature. If the machine
