有些车主会因为发动机温度高而盲目拆除节温器,这样做的话,使得冷却液只能进行大循环,不能调节冷却强度,难以发动机在较适宜的温度下工作,反而使发动机经常处于低温状态下工作,造成发动机功率下降,磨损加快,油耗增加。
Some car owners will blindly remove the thermostat because the engine temperature is high. If they do so, the coolant can only carry out large circulation and can not adjust the cooling intensity. It is difficult for the engine to work at a more appropriate temperature. On the contrary, the engine often works at a low temperature, resulting in reduced engine power, accelerated wear and increased fuel consumption.
正确做法:如果发动机节温器发生故障检修或更换之后,发动机温度还高,就应检修冷却系统的其他部位。
Correct practice: if the engine temperature is still high after troubleshooting or replacement of the engine thermostat, overhaul other parts of the cooling system.
第二个:发动机温度怕高不怕低
Second: the engine temperature is afraid of high and not afraid of low
当发动机经常处于低温状态下工作时,会造成发动机功率下降,磨损加快,油耗增加。
When the engine often works at low temperature, it will reduce engine power, accelerate wear and increase fuel consumption.
东莞奔驰配件厂建议:应根据汽车使用说明书规定的正常温度行车,以发动机的使用寿命。
Dongguan Benz parts factory suggests that the vehicle should be driven according to the normal temperature specified in the vehicle operation manual to ensure the service life of the engine.
第三个:水泵风扇皮带越紧越好
Third: the tighter the water pump fan belt, the better
当皮带过紧不仅会使其拉长或断裂,缩短皮带的使用寿命,而且还会因拉力过大,导致发电机轴、水泵轴变形弯曲和轴承的早期损坏。
When the belt is too tight, it will not only lengthen or break and shorten the service life of the belt, but also lead to deformation and bending of generator shaft and water pump shaft and early damage of bearings due to excessive tension.
建议:汽车发动机风扇皮带的松紧度应符合技术要求,一般正常皮带装配时挠曲度为10-15mm为宜。
Suggestion: the tightness of automobile engine fan belt shall meet the technical requirements. Generally, the deflection during normal belt assembly is 10-15mm.
第四个:发动机用怠速升温
Fourth: warm up the engine at idle speed
当发动机用怠速升温时,由于转速较低,机油泵不能较快地将润滑油压入各润滑表面,油压也低,使发动机各运动机件在干摩擦或半干摩擦状态下工作;燃油因低温雾化不良,使未燃烧的燃油(混合气)窜入曲轴箱,冲刷掉缸壁上的油膜,也会加速机件的磨损。
When the engine is heated at idle speed, due to the low speed, the oil pump can not quickly put the lubricating oil pressure into each lubricating surface, and the oil pressure is also low, so that all moving parts of the engine work under dry friction or semi dry friction; Due to poor low-temperature atomization of fuel, unburned fuel (mixture) rushes into the crankcase and washes off the oil film on the cylinder wall, which will also accelerate the wear of parts.
建议:当发动机启动数秒后,应用快怠速升温,改善发动机的润滑条件。
Suggestion: when the engine is started for several seconds, apply fast idle speed to raise the temperature and improve the lubrication conditions of the engine.
第五个:用喷灯烘烤油底
Fifth: bake the oil pan with a blowtorch
很多车主在冬天的时候,喜欢用喷灯烘烤油底,这样做不但会使机油中的添加剂发生化学变化,失去原有的性能,而且还会使机油胶结、油底变形,容易引起火灾。
Many car owners like to bake the oil bottom with blowtorch in winter. This will not only make the additives in the engine oil chemically change and lose their original performance, but also make the engine oil cemented and the oil bottom deformed, which is easy to cause fire.
