Conservation of car must be talking about science. But, in the vehicle maintenance problems often arise, and some people originally thought it was in the maintenance of cars, but actually damaged the car self-defeating. Conservation experts have warned that the following 12 kinds of errors is equal to destroying vehicles and maintenance method.
one, under the hot sun washing cars - Injury Auto Paint
Many car owners prefer to wash under the hot sun, believing it will soon be washed the car body of water dried in the sun. Actually the wrong men, and in the hot sun, car washing, water droplets formed by the convex lens effect will paintwork of the top local high temperatures generated long period of time, and paintwork will lose luster. If at this time waxing, it tends to result in uneven body color. Therefore, the car wash waxing preferably carried out under conditions of shelter, if not guaranteed, then preferably in cloudy or sunny morning, in the evening.
2, car wash, like taking a bath - victims of air-conditioning
Summer temperatures, dust increase, the body easily dirty, the frequency of car wash owners have begun to rise, many car owners in the car wash when they want to wash myself as confused as the can thoroughly. But the thing to note here is that we must maintain the appearance of automotive air conditioning and dry, air-conditioning did not care if the car is wet, it will affect the automotive air conditioning life.
3, circle method waxing - poor results
Many people are accustomed to the car body waxing in a circle manner manner, it is not the right approach. Waxing is the right way means a straight line and horizontal line of alternating, then the direction of the flow of rain the last one, in order to reduce the paintwork surface of the concentric ring-shaped effect.
4, oil too - failure
When the engine oil sump of the oil shortage, the bearing and journal, etc. The less friction and lubrication oil due to poor, increasing wear and tear, and even lead to burning ZWZ accident. If, however, too much oil, the engine crank handle at work, connecting rod big end will produce severe agitation, not only increase the power loss inside the engine, but also to an increase in oil splashed on the cylinder wall, resulting in burning row of oil failure . Therefore, the engine oil sump of the oil should be controlled in the oil-foot upper and lower is better between the engraved lines.
5, bolts too tight - permanent deformation
The car with bolts, nuts, fasteners connected a lot, should ensure that they have sufficient preload force, but they can not screw too tight. If the screw too tight on the one hand will allow connectors under the influence of external forces resulting in permanent deformation; the other hand, would produce tensile bolts permanent deformation preload declines and even cause the phenomenon of sliding buckle or break.
6, the fan belt too tight - bearing load large
Summer temperatures are too high, some drivers think that increasing the fan belt tightness, can improve the engine cooling effect, so it features a move to improve the tightness of the fan belt, causing the fan belt too tight, not knowing this approach is wrong. Fan belt should remain elastic appropriate, as will tight bearing load is too large, increasing wear and tear, power consumption increases, but also water pump shaft will bend, stretch belt deformation, shortened life expectancy.
7, import tires - Not Applicable
Some people buy tires particularly fond of emphasis on "Import." Abroad, pushing the new tires on the domestic users, there is one of the most fatal flaw is not applicable. European flat surface with the Beijing Second Ring Road, Ring road conditions are very different for the European road tires in Beijing, can hardly be a good performance, especially with impact-resistant sidewall obviously some lack of acclimatization, just like wearing Italian brand-name shoes, walking the gravel in general, sidewall packages from inevitable. Number of foreign brands in the domestic joint venture to produce tires after they have been in accordance with domestic conditions in the tire side of the road increased by a layer of tire cord fabric, which greatly enhances the sidewall of the impact force, a joint venture production of tires from the performance in terms of imported goods is fully capable of substitution .
8, the new battery does not charge - to shorten life expectancy
The first charge is called the initial battery charge, the initial charging of the battery life have a great impact. If charging, that is, add "water" direct use, battery capacity is not high, life expectancy will be shortened; if direct charging will shorten the life span. Usually the initial battery charging is finished filling electrolyte after charging with a small current is about 1 hour or so can be installed to use.
9, in-vehicle equipment, casual plus - impact of road safety
Private car is the mobile home owners, the pursuit of comfort and luxury is nothing wrong with the ride, but some owners installing their own hands in the car devices, such modification, if not handled properly, the car performance and the convenience and reliability are often manipulated is adversely affected by side effects or affect the easy road safety.
10, cooling water temperature is too low - worn engine
Summer, hot weather, and some drivers to prevent the engine temperature is too high by insisting on a low cooling water temperature as much as possible; some drivers, in order to achieve the purpose of cooling down, simply remove the thermostat, such practices are wrong.
Automobile Engine both Heat intolerance also stand the cold, if the cooling water temperature is too low will lead to deterioration of fuel burn, fuel consumption increased, exacerbated wear, oil viscosity increase in engine power reduction. Tests showed that vehicles running cooling water temperature is 40-50 degrees Celsius, the engine wear increased by 60% -80%, power reduced by 25%, 8% -10% increase in fuel consumption. Therefore, the engine cooling water temperature is not lower the better, in general should be controlled between 80-90 degrees Celsius.
11, water tanks, "Kai Guo," Speed added water - Cylinder crack
Hot summer weather, some drivers, a water tank to see a "Kaiguo" phenomenon, they worry that the engine temperature increases further, immediately turn off water. This approach is wrong, and it may well result in the cylinder head because of the sudden the cold cracking phenomenon emerged.
If you run into water tanks, "Kai Guo", generally the right approach is: an immediate stop to allow the engine to keep idling to heat; the same time, open the hood to improve heat rate. When the cooling water temperature is reduced, then the engine flameout. At this point, if the number of insufficient cooling water should be added slowly to prevent the cylinder Gein suddenly appeared by the cold and cracking.
12, a long-term without car or a short car - mechanical damage
Although some people became drivers often, but usually "not willing to" move on, and only leave when the car went out to play, in fact, the car mode is very hurt cars. Engine and gearbox and other transmission parts the surface is a result of regular direct contact with air condition and rust, battery also because of the long-term impact on the natural discharge life. The best way is to run a car every few days, running a thirty or forty minutes. In addition, injuries are always short-haul vehicles will be cars, trucks moving at any time but they opened not far, is an important reason for injury car.
Car parts in the engine start to wear and tear of the most serious between the stabilization phase, to launch a car battery power is also consumed approximately 20 minutes driving to make up for such cars used cars easily go wrong earlier. (Change)
