Some wrong maintenance methods
If the blinder is removed due to high engine temperature, cooling The liquid can only perform large circulation, can not adjust the cooling intensity, it is difficult to ensure that the engine works at a more suitable temperature, but the engine is often working at a low temperature, resulting in a decrease in engine power, accelerated wear, increased fuel consumption. If the engine thermostat occurs After troubleshooting or replacement, if the engine temperature is still high, other parts of the cooling system should be inspected and the thermostat can not be removed. 2, the engine temperature is not afraid of high fear of low Some people think that the engine temperature is not afraid of high when driving, not afraid of low. In fact, when the engine temperature is low, the harm is also very great. Should be based on the normal temperature of the car instructions to drive in order to ensure the life of the engine. 3, engine idling temperature When using idling heating, due to the low speed, the oil pump can not quickly press the lubricating oil into the various lubrication surfaces, the oil pressure is also low, so that the engine parts in the engine work under dry friction or semi-dry friction; fuel due to low temperature Poor atomization causes unburned fuel (air-fuel mixture) to enter the crankcase and flush away the oil film on the cylinder wall, which also accelerates the wear of the engine parts. Therefore, after the engine is started for a few seconds, the application of the engine is accelerated at a fast speed (in a modern car). Specially equipped with fast idle device, after the engine temperature rises, it will automatically adjust to idle state) to improve the lubrication conditions of the engine. 4, the tighter the water pump fan belt The tighter the belt is not the better. The belt is too tight will not only make it stretch or break, shorten the service life of the belt, but also due to too much tension, leading to distortion of the generator shaft, the water pump shaft and early damage to the bearing. The tightness of the fan belt should meet the technical requirements. Normally, the deflection of the normal belt is 10-15mm. 5, use the torch to bake the oil The use of a blowtorch to bake the oil in the winter will not only chemically change the additives in the oil and lose the original performance, but it will also cause the oil to gel and deform the oil base, which will easily cause fire. The best practice is to base on the local winter minimum The temperature is selected with the appropriate engine oil. It is best to park the vehicle in a garage with insulation facilities where conditions permit. The more advanced methods of removal are ultrasonic cleaning and nuclear cleaning. However, the most common and simplest methods are physical removal and chemical removal. These two methods can also be used together.
