1. Metamorphic use of oil, resulting in the engine filter does not work
Automobile engine needs to use oil for lubrication, but if there was a bad car in the used motor oil, oil will take care of the car's engine to produce some extremely poor circumstances, appeared counterproductive. In using metamorphic of oil Shi, due to oil of itself situation will will led to oil in after filter of fine hole Shi, appeared will oil of impurities also with with into filter device among, then of oil if in long-term using of situation Xia, on will led to filter device appeared jam of status, led oil constantly not can smooth of through filter, oil itself of lubrication role greatly reduction value, even due to through bypass valve and into to has engine of lubrication parts, instead will put oil of filter burst, such on will increased for engine of wear , Thus reducing the engine's lifespan. Therefore, when you use oil, according to the usage of engine oil change in a timely manner, to reduce oil deterioration caused by engine failure.
2. Fuel system flow caused by engine trouble, that doesn't start the car
Car in driving process among will produced large of fuel, these fuel in flows combustion chamber Shi, due to itself carry of some debris cannot for itself of purification, this on led to has these debris will with fuel stranded Yu oil hole, and spray pump and spray nozzle Shang, dang these debris accumulated to must degree of Shi, on will effect fuel itself of conveying and circulation, if not timely for cleanup, even also will caused these impurities also followed up combustion chamber, eventually led to has engine appeared some performance not stable, and Unable to pick up, or underpowered. In order to reduce such a problem, testing the fuel channels in a timely manner to protect fuel system flow at any time, avoiding fuel due to obstruction of the channel not be able to supply, eventually led to the car will not start.
3. Car engine cooling system in operation in adverse conditions
For engines, if the cooling system be unable to conduct normal operations, then the engine will be at a high temperature for a long time, which would lead to a variety of engine failures and be unable to conduct normal operations. In practical terms, car engine cooling systems are more common, such as piston cylinder, noise increase power, detonation or explosive shaking and accelerating decline, most of these are due to the cooling system malfunction and cause the engine to overheat and generate some problems. In addition, if the tank rusting and scaling occurs, and also will cause the cooling system to carry out good work, because they could not be fully play thermal effect of cooling liquid, eventually making huge damage due to overheating of the engine, and this will shorten engine life.
