What happens if the fuel injector is blocked?

Fuel injector is one of the key components of EFI engine, and its working condition will directly affect the performance of the engine. Nozzle blockage will seriously affect the performance of the car.

The working quality of the fuel injector plays a vital role in the power of each engine. Poor fuel will lead to poor fuel injectors, serious carbon deposition in cylinders, accelerated wear of cylinders and piston rings, unstable idle speed, rising fuel consumption, weak acceleration, difficult start-up and excessive emissions; Serious will completely block the fuel injector and damage the engine. Therefore, it is necessary to clean the nozzle regularly. Long-term non-cleaning or frequent cleaning of the nozzle will have a bad influence.

When the injector is slightly blocked, it also has a certain impact on the vehicle condition. Sometimes, there will be such a fault: when the first gear starts, the car shakes a little, and when it accelerates in the high gear, this phenomenon disappears again. If all kinds of sensors on the vehicle work normally, the throttle body is clean and the circuit is normal, it is likely that the fuel injector is slightly blocked. However, when accelerating in high gear, slight gum may be sprayed away (dissolved) again, and the performance of the car will be restored. This slight blockage of the fuel nozzle usually does not require cleaning. Because slight gum can be dissolved. Therefore, frequent high-speed running can reduce the formation of carbon deposits. If the injector is not cleaned for a long time, the blockage will become more and more serious, resulting in poor fuel injection, poor fuel injection angle and atomization, poor engine work at idle speed, acceleration or full load, reduced engine power, increased fuel consumption, increased emission pollution and even failure of the engine. Therefore, the nozzle should be carefully cleaned and inspected regularly to ensure its good work.
