Why the fuel injector of the car is blocked

Poor fuel will cause the fuel injector to not work well, causing the carbon accumulation in the cylinder to be serious, and the cylinder and piston ring to accelerate and wear, resulting in unstable idle speed, rising fuel consumption, weak acceleration, difficult starting and exceeding the standard emission; If it is serious, it will completely block the fuel injection nozzle and damage the engine.

Because gasoline itself contains glue, impurities, or dust, impurities, etc. brought in during storage and transportation, it accumulates sludge-like sediments in automobile fuel tanks, oil intake pipes and other parts; secondly, because the unstable components in gasoline react at a certain temperature, forming glue and resin-like adhesions Thick matter.

If the fuel injector is blocked, the engine will have problems such as jitter, lack of cylinder, insufficient power, increased fuel consumption, and exhaust emissions exceeding the standard.There are two reasons for the blockage of the nozzle. One is that there are many impurities in the fuel. If there is a problem with the fuel filter, it is easy to block the nozzle. Another thing is that the carbon accumulation of the engine will also block the nozzle, affecting the atomization effect.

How often is the car fuel injector be cleaned

The fuel injector is generally cleaned every 2 years or 50,000 to 80,000 kilometers It's okay. It depends on the quality of the gasoline in the area where the vehicle is used.There are two ways to use the fuel injector: one is disassembly-free cleaning, and the other is disassembly and installation cleaning.

The nozzle is generally cleaned every two years or 40,000 to 60,000 kilometers. The fuel injector is actually a solenoid valve. When the electromagnetic current flows, the suction force generated will suck up the needle valve and open the nozzle. The fuel will be sprayed at high speed through the ring gap between the axial needle at the head of the needle valve and the nozzle, forming a mist, which is conducive to full combustion.

If the car is in good condition and the oil quality is good, it is recommended to clean it every 40,000-60,000 kilometers. Even if the fuel injector is slightly blocked, there is no need to be too nervous, because when the high-end acceleration, the impurities can be sprayed away and dissolved.

The fuel injector can generally be cleaned once every 2 years or 50,000 to 80,000 kilometers, depending on the quality of gasoline in the area where the vehicle is used.

The fuel injector is usually cleaned once every 2 to 3 kilometers. The fuel injector of a car is a simple solenoid valve. When the electromagnetic coil is energized, suction is generated, the needle valve is sucked up, the nozzle is opened, and the fuel is sprayed at high speed through the ring gap between the shaft needle and the nozzle of the needle head of the needle valve, forming a fog, which is conducive to full combustion.

How to maintain the fuel injector of a car?

Usually, it is recommended to clean the fuel nozzle every 20,000 kilometers. For ordinary car owners, it is no problem to clean 30,000 kilometers once to ensure that the vehicle is in good condition and fuel quality. Usually, something similar to additives is used to keep the fuel nozzle clean.

There are two ways to use the fuel injector: one is disassembly-free cleaning, and the other is disassembly and cleaning.

It can be dredged with a needle. After dredging, the latitude and weft should be carefully cleaned. The large plane of the needle valve body has poor contact with the main plane of the fuel injector, or the cylindrical surface of the needle valve is worn out.

First, don't coax the accelerator with your big feet, especially when the fuel injector is blocked, the big foot will cause the fuel injector to be completely damaged.

It is generally recommended to clean the fuel injector of the car once every 10,000 to 20,000 kilometers. If the condition of the vehicle is relatively good and the vehicle does not have the problems mentioned above, it is also possible to extend it to 30,000 kilometers to clean it once. After cleaning the fuel injector of the old car, you can feel that the car is more smooth to use. It's smooth.

How to maintain the fuel injector of the car? It is necessary to clean the fuel injector.

How often should the fuel injector of a car be changed?

1. [Pacific Automobile Network] The fuel injector is not a part that needs to be replaced regularly. As long as this part is not damaged, it does not need to be replaced. However, the fuel injector of the car needs to be cleaned regularly, every 2 years or 50,000 to 80,000 kilometers. Long-term non-cleaning or frequent cleaning of the fuel injector will have a bad impact.

2. Car fuel injector replacement cycle: The fuel injector is generally cleaned every 20,000 kilometers. If there is no malfunction, the fuel injector will basically not be replaced. It is recommended to replace the gasoline filter in time, otherwise the nozzle is prone to dirty blockage; now the general electronic fuel injector is recommended that the owner in 1 year or 200 Clean once at 00 kilometers.

3. The fuel injector should be replaced every 2 years. According to the relevant queryThe information shows that the fuel injector is not a part that needs to be replaced regularly. As long as the part is not damaged, it does not need to be replaced.

4. The fuel injector does not need to be replaced. Under the condition that the vehicle is in good condition, when the vehicle is idling normally, it does not need to be replaced, and it can be cleaned regularly.

5. The nozzle is not a part that needs to be replaced regularly. As long as this part is not damaged, it does not need to be replaced. If the nozzle is damaged, it needs to be replaced. The nozzle belongs to the fuel supply system of the car engine and can inject fuel. There are three types of fuel injection for automobile engines, namely hybrid injection, in-cylinder direct injection and multi-point electric injection.
