People in the use and maintenance of the car there are some errors, these errors are in the low level of automobile manufacturing, repair means backward, lack of means of detection in the long term formation. These false belief can sometimes seem right, actually otherwise, with great harm, will make the vehicle damage and personal safety is threatened, and greater are thus buried the hidden dangers of accidents, or caused by vehicle performance decline, accelerated wear and tear, life shortening.
1, blind down the engine thermostat
If due to high engine temperature and blindly remove thermostat, cooling liquid can only for high cycle, can not adjust the cooling intensity, it is difficult to guarantee the engine operates under suitable temperature, but so often in the engine working under low temperature, resulting in a decline in the power of the engine, wear accelerated, increased fuel consumption. If the engine thermostat fails to repair or replace, the engine temperature is still high, it should be the other parts of the cooling system, can not remove the thermostat.
2, the engine temperature is afraid of high fear of low
Some people think that when driving the engine temperature is afraid of high fear low. In fact, the engine temperature is low when the harm is great. The service life of the engine can be ensured according to the normal temperature driving according to the specification of the automobile.
3, water pump fan belt tightening the better
The tighter the belt is, 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, the engine idle speed up
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 low temperature atomization, the unburned fuel (mixed gas channeling into the crankcase, washing away on the cylinder wall oil film, will also accelerate the mechanical wear and tear. Therefore, the engine start a few seconds after the application of fast idle speed up (in the modern car designed with a fast idle device, the temperature rise, will automatically adjust to the idle state), improve the engine lubrication conditions.
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. The best practice is to use the minimum temperature in the local winter to adapt to the oil. In a conditional place, it is best to park vehicles in a thermal insulation facilities in the garage.
The more advanced cleaning methods are ultrasonic cleaning and spray cleaning, but the most simple method is the physical removal and chemical cleaning method. These two methods can be used. |
