What is an automobile fuel nozzle? When does the nozzle need cleaning?

I believe many car owners have heard of the word nozzle. When we usually go to the garage, we often hear the mechanic say that the nozzle of the car is blocked and needs cleaning. Hearing these suggestions, we are also at a loss. Let me tell you what a car nozzle is and when it needs cleaning.

You can see from the name of the nozzle that the fuel is ejected. The main working principle is that when the ECU sends a signal to the nozzle, the current will flow into the coil in the nozzle ring, generating a magnetic field to suck up the valve needle of the nozzle valve and let the fuel be ejected from the nozzle valve. As for how much to spray, it depends on the technology of the car manufacturer. Generally, we hear that the air-fuel ratio of an automobile engine is also determined by how much fuel is sprayed from the nozzle.

If the goods we use are not good, the fuel nozzle will be easily blocked by carbon deposits, which will lead to poor fuel injection and make the vehicle shake or lack of power when driving. This is what we usually say that the fuel consumption of old cars will increase when the power tiger is relatively weakened, which is largely due to the blockage of the throttle. In severe cases, it will also cause the engine to be out of cylinder or the vehicle to be difficult to start or even unable to start. When this happens, we need to consider cleaning the fuel nozzle.

Generally speaking, it is recommended to clean the throttle of the car every 1 10,000 to 20,000 kilometers. If the vehicle is in good condition and the vehicle does not have the above problems, the cleaning time can also be extended to 30 thousand kilometers. After the old car has cleaned the gas nozzle, it can be felt that the vehicle is used more smoothly.

Cleaning the nozzle does not need to be disassembled and started, and the owner does not have to worry too much. He mainly uses fuel system cleaner to clean. If the engine is found to be weak, the fuel nozzle should be cleaned in time. Once the nozzle is seriously blocked, the damage to the engine is irreversible. What are the above automobile fuel nozzles and when do they need cleaning? I hope it helps you.
