Today, let's study the automobile fuel nozzle. As a key component of EFI engine, the fuel injector is actually a simple solenoid valve, which is used to control fuel injection and make fuel burn more fully! The working quality of injector directly affects the performance of engine. This paper will simply analyze: How often is it most appropriate to clean the fuel nozzle of an automobile?

If the nozzle is not cleaned for a long time, it will leak or block. If it is blocked, the gasoline it emits will not be atomized normally, and the exhaust pipe of the car will emit black smoke. Then the lack of cylinder will cause a cylinder of the engine not to work. After the cylinder is missing, the engine will also have obvious external manifestations such as jitter and acceleration weakness.

Therefore, it is necessary to clean the nozzle regularly. How often do you clean the nozzle? Remember at this time that different situations have different treatment methods! The first is the judgment of slight congestion. There is jitter at the start of the first gear, and it disappears after the high-end acceleration. Car owners are advised to run at high speed. After all, when the car accelerates in high gear, the slight gum is sprayed away (dissolved), so in the case of slight congestion, it is generally not necessary to clean it.

Thirdly, the traffic jam is serious, which should be determined according to the condition of the car and the quality of the oil added in peacetime. Under normal circumstances, users are advised to check and clean once every 30,000-40,000 kilometers. If the car is in good condition and the fuel quality is good, it can be cleaned every 60-70 thousand kilometers.

Finally, don't clean the nozzle alone, but thoroughly clean the oil circuit. After all, the carbon deposit in the oil circuit is "everywhere", not only on the nozzle alone, but also has little effect of cleaning alone!

Also, under normal circumstances, the nozzle does not need to be replaced. Even if there is carbon deposit blockage, it only needs to be cleaned. Don't listen to the so-called "replacement" suggestions of some repair shops.
