The term "automobile maintenance" has reached a consensus among the majority of automobile users. Most car owners can maintain their cars within the prescribed time. Cars are better. But the owner's maintenance awareness is often limited to where to repair and where to change. But the deep maintenance of the car is not so important.
As the saying goes, a stitch in time saves nine. , slight disease, severe disease pain, this project is a solidified depth image. If we usually do irregular depth maintenance, according to the project customer's vehicle, there will be one or another problem, such as small steam, fuel consumption, weak acceleration, high water temperature, etc., which is paralyzed and unable to drive. Deep maintenance is a general trend, which has been widely used in industrialized and urbanized Europe and the United States. With the rapid development of China's economy, cars have entered thousands of households. As a means of transportation, cars bring people a convenient, fast and comfortable life, so that people can feel the convenience and happiness of driving.
The so-called deep maintenance is to remove the sludge, carbon deposit, scale, rust and other harmful substances generated in various machines after the operation of the car, so as to restore or improve the function of the car.
The fuel system consists of nozzle, intake valve, combustion chamber, throttle valve and intake manifold. Deposits on these components can reduce fuel economy, impair driving performance, and affect engine performance, even with premium gasoline. The deposition of fuel system will not only pollute the environment, but also produce excessive exhaust gas in the annual vehicle inspection. Removal of these deposits will help to reduce emissions of harmful gases.
Antifreeze will decay after use for a period of time, and the protective performance will decline. This is also the beginning of corrosion in the cooling system, which will affect the flow of coolant over time, resulting in overheating of the engine. The maintenance of the cooling system can prevent the engine from boiling in summer and freezing in winter, thus prolonging the service life of the engine cooling system and water pump.
Overheating is the main cause of gearbox damage. Sediment is produced in the whole transmission system, and the sediment in the transmission radiator prevents the transmission oil from cooling completely, resulting in premature transmission failure. Regular maintenance of the gearbox can extend the service life of the gearbox.
Every 10000 to 20000 kilometers of vehicle driving; due to the poor quality of oil products, the micropore of the three-way catalytic converter is blocked and invalid, the fuel sulfur content is high, the catalytic cleaner is poisoned and invalid, resulting in insufficient power; the fuel combustion is insufficient, carbon monoxide and carbon deposition and other substances, resulting in the three-way poisoning and invalid, the engine exhaust is overheated, resulting in the three-way catalytic sintering and so on.
