Is it necessary to clean the engine?

If the automobile engine is not often cleaned with cleaning agent, the carbon deposit will become thicker and thicker, which will lead to the lax valve closure and the decline of engine performance, which is manifested in a series of failures such as unsmooth acceleration, unstable idle speed, stall, jitter and knock. Seriously threaten the service life of the car.

Matters needing attention in automobile engine maintenance

1, clean the air filter

The air filter is directly related to the air intake of the engine when the car is running. The manager of Guangben dealership told the reporter that the air filter will not be blocked when the car is only driving in the urban area, but if the car is driving on dusty roads, it is necessary to pay special attention to the cleanliness of the air filter.

If the air filter is blocked or there is too much dust, the air inlet of the engine will be blocked, and a large amount of dust will enter the cylinder, which will accelerate the carbon deposition speed of the cylinder, which will hinder the ignition of the engine and cause insufficient power, and the fuel consumption of the vehicle will naturally increase. If you drive on a normal city road, you should check the air filter when the car travels 5000 kilometers. If there is too much dust on the filter element, consider using compressed air to blow out the dust inside the filter element. But the pressure of compressed air should not be too high to avoid damaging the filter paper. He told reporters that water or oil must not be used when cleaning the air filter to prevent oil and water from soaking the filter element.

2. Remove throttling sludge

There are many reasons for fouling at the throttle, some of which are carbon deposits formed by the exhaust gas from fuel combustion at the throttle; Then, impurities that are not filtered by the air cleaner will remain on the throttle. Too much sludge will cause air resistance and increase fuel consumption.

He said that the car should clean the throttle when driving 10000 to 20000 kilometers. When cleaning the throttle valve, first remove the intake pipe, expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of "carburetor cleaner" into the throttle valve, and then carefully scrub it with a polyester rag or a high-spin "non-woven fabric". Deep in the throttle, you can clip a rag and scrub it carefully. After cleaning, install the intake pipe and the negative electrode of the battery, and you can ignite!

3, clean up the nozzle carbon deposit

Because the combustion chamber is easy to produce carbon deposit, it is difficult to start; Carbon deposition in the fuel nozzle will also lead to oil blockage, gasoline injection deformation, poor atomization, and fuel consumption will naturally increase.

For the cleaning of the combustion chamber, a special carbon remover can be used to soften the carbon deposits on the combustion chamber and the fuel nozzle and separate them from the surface of the parts, and then remove the softened carbon deposits. This method of removing carbon has a good effect. Compared with the previous direct wiping, it has the advantage of not damaging the surface of parts, and the efficiency of removing carbon has also been greatly improved.
