How often do you clean the throttle nozzle?

Time for cleaning the throttle nozzle of Pacific Auto Network: If the car is in good condition and the oil quality is good, it can be done every 40,000-60,000 kilometers. Automobile fuel injector is a simple electromagnetic valve, which generates suction, the needle valve is sucked up, the nozzle hole is opened, and the fuel is ejected at high speed through the annular gap between the shaft pin at the head of the needle valve and the nozzle hole, forming a mist. Its quality determines the performance of the engine. If the nozzle is blocked, it will directly affect the performance of the car.

When the fuel nozzle becomes dirty, the car will have the following obvious performances:

1, the engine noise becomes louder, especially in low gear;

2. The throttle response is not sensitive, the driving is not smooth, and there is a lag phenomenon after stepping on the throttle. After stepping on the accelerator in neutral, the engine speed rises slowly;

3, idle jitter, especially when starting, it is easy to shake, and there is a slight lack of cylinder when upshifting at low gear and low speed.

Causes of nozzle blockage:

Because gasoline itself contains colloid and impurities, or dust and impurities brought in during storage and transportation, deposits similar to sludge are formed in automobile fuel tanks, oil intake pipes and other parts over time; Secondly, the unstable components in gasoline react at a certain temperature to form colloid and resin-like viscous bodies. When these viscous substances are burned in the nozzle, intake valve and other parts, the deposits will become hard carbon deposits. This situation will lead to accelerated engine wear, unstable idle speed, rising fuel consumption, weak acceleration and difficult starting.
