People in the use and maintenance of automobiles in the automobile manufacturing level is low, repair methods backward, lack of means of detection in the era of long-term formation. These false belief sometimes seems right, in fact, has great harm, will make the vehicle damage and personal safety is threatened, and the greater likelihood is thus laid the hidden dangers of accidents or cause decrease of vehicle performance, wear speed and short service life etc..
1> tear down the thermostat of the engine blindly
If the engine temperature is high and the blind demolition beiben V3 parts thermostat, coolant can proceed big circulation, can adjust the cooling intensity, it is difficult to ensure the engine working at a suitable temperature, but the engine is often in low temperature condition, the engine power decreased, wear faster, increased fuel consumption. If the engine thermostat fails, after repair or replacement, the engine temperature is still high, the other parts of the cooling system should be repaired, and the thermostat can not be removed.
2> engine temperature is afraid of high, not afraid of low
Some people think that when driving north, running V3 parts, engine temperature is high, not afraid of low. In fact, when the engine temperature is low, the harm is also great. The service life of the engine shall be guaranteed according to the normal temperature prescribed by the instruction manual.
3> pump fan belt as tight as possible
North running V3 accessories belt tight, not the better. The belt is too tight, not only will it lengthen or break, shorten the service life of the belt, and will cause the generator shaft, the water pump shaft to deform, bend and the early damage of the bearing because of the too big pulling force. The tightness of the fan belt of the automobile engine shall comply with the technical requirements. When the normal belt is assembled, the deflection shall be 10-15mm.
4> engine heating at idle
With the idle temperature, due to the low speed, the oil pump can not quickly the lubricating oil into the lubricating oil pressure is low, the surface of the moving engine parts under dry friction or semi dry friction condition; low temperature fuel due to poor atomization, the unburned fuel (gas) into the crankcase, scouring out of the oil film on the cylinder wall, will accelerate the wear parts. Therefore, after a few seconds of engine start, the application of fast idle heating, improve engine lubrication conditions.
5> burner for baking oil bottom
Winter burner for baking oil bottom, it will not only make the additives in the oil and chemical changes, loss of the original performance, but also the oil cement, oil bottom deformation, easy to cause fire. The best thing to do is to select the suitable oil for the local minimum winter temperature. Where conditions permit, it is better to park the vehicle in a garage with thermal insulation. The more advanced methods of cleaning are ultrasonic cleaning and spray cleaning, but the most widely used and simplest methods are physical cleaning and chemical cleaning. These two methods can also be used concurrently.
