With the development of economy, many people have bought cars, but many people only know to buy cars, but they don't really understand cars. When there is a problem with the car, Chinese people generally know how to repair the car, but they don't know how to maintain the car. In addition to changing some oil, they won't change anything else. In this way, the car is prone to some small problems. Is it good to clean the valve of the car in addition to the usual maintenance?
What is the throttle and what role does it play?
Throttle valve is a controllable valve used to control air entering the engine. After entering the intake pipe, it mixes with gasoline to become a combustible mixture and participate in combustion work. Throttle is one of the most important components of the engine system of EFI vehicles. Its upper part is the air filter and the lower part is the engine block. It is the throat of the automobile engine. Whether the car accelerates flexibly has a lot to do with the dirt on the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and powerful.
Throttle valve cleaning and carbon deposit cleaning mainly depend on the engine structure. In terms of the service environment, general vehicles do not need to clean the throttle valve and carbon deposit frequently. Direct injection engines are more prone to carbon deposit, which does not mean that the throttle valve and carbon deposit are cleaned every maintenance. For carbon deposit cleaning, the intake branch pipe should be removed, the spark plug should be removed, and the high-pressure air pipe should be connected at the spark plug port, Let the combustion chamber form a positive pressure to prevent the carbon deposit under removal from falling into the cylinder.
Clean up the carbon deposits on the branch pipes and intake and exhaust valve seat pipes. This is quite professional. The maintenance factory needs to turn the crankshaft with a wrench to close the intake and exhaust valves, use a shovel to slowly remove the carbon deposits, and then blow out the carbon deposits with high-pressure air. Carburetor cleaning agent is also used. The carbon deposits of the steam engine do not need to be cleaned frequently, You don't need to wash it often. You have to say important things three times.
Generally, it's good to clean it once every 60000 to 80000 kilometers. As long as the engine burns oil, it will form carbon deposits, but don't over maintain it. In addition, the hanging bottle can also be used. The hanging bottle can clean the fuel injection nozzle and carbon deposits in the cylinder. The hanging bottle cannot clean the carbon deposit at the inlet manifold and gas door. It needs to be removed for cleaning.
