The engine can't be easily disassembled
Time:2015-12-4
People in the use and maintenance of vehicles in the presence of a number of errors, these errors are in the low level of automobile manufacturing, repair means backward, lack of detection means in the era of long-term formation. These mistakes sometimes seem right, in fact, otherwise, a great harm, will make the vehicle was threatened, and the greater the risk of accidents, or cause the vehicle performance degradation, wear faster, shorten life.
1, the engine section of the blind removed thermostat
If the engine temperature is high and the temperature is high, the cooling liquid can only carry on the big circulation, and can not adjust the cooling intensity, it is difficult to guarantee the engine to work at a more suitable temperature, but the engine is often in the low temperature condition, resulting in engine power loss, grinding loss, fuel consumption. If the engine thermostat failure repair or replacement, the engine temperature is high, it should be the other parts of the cooling system, can not remove the thermostat.
2, engine temperature is afraid of high not afraid of low
Some people think that the engine temperature is not high and low. In fact, the engine temperature is also very low hazard. In order to guarantee the service life of the engine, the vehicle should be used according to the normal temperature driving instructions.
3, the pump fan belt tightening the better
The belt tightening is not the better. The belt is too tight will not only make the elongated or fracture, shorten the service life of the belt, but also because of the tension is too large, resulting in generator shaft, pump shaft deformation of bending and bearing early damage. Engine fan belt tightness should meet the technical requirements, the normal deflection when the belt assembly is appropriate for the 10-15mm.
4, engine idle temperature
Idle temperature, due to the lower speed, the oil pump can not quickly the lubricating oil into the lubricating surface, oil is also low, so that the moving parts of the engine in the dry or semi dry friction condition; fuel due to poor atomization low-temperature, channeling unburned fuel into the crankcase, washing away on the cylinder wall oil film, will also accelerate the mechanical wear and tear. So, after the engine starts for a few seconds, the application of fast idle heating, improve engine lubrication condition.
5, burner for baking oil bottom
Winter burner baking oil bottom, will not only make the additives oil and chemical changes, loss of the original performance, but also to oil cementing, oil bottom deformation, easy to cause a fire. Best practice is based on the minimum temperature of the local winter to adapt to the oil. In a conditional place, it is best to park the vehicle in a parking garage with an insulation facility. The advanced removal method is ultrasonic cleaning method and the method of removing the nuclear, but the most simple method is the physical removal method and chemical removal method. These two methods can be used.
