How To Know If The Injector Is Clogged

Methods for judging whether the injector is clogged include observing the color of the exhaust pipe, checking the working status of the injector, checking the injection effect and using professional testing equipment.

Observe the color of the exhaust pipe: Under normal circumstances, the exhaust gas discharged from the exhaust pipe should be colorless or light blue. If the exhaust gas discharged from the exhaust pipe presents white smoke, it means that the injector is clogged, resulting in incomplete combustion. If the exhaust gas is black smoke, it means that the mixture is too rich and the injector is seriously clogged.

Check the working status of the injector: You can judge whether the injector is clogged by checking the working status of the injector. If the injector works normally, the injection amount and injection time are accurate, indicating that the injector is not clogged. If the injection amount or injection time is abnormal, it means that the injector is clogged and needs to be cleaned or replaced.

Check the injection effect of the injector: You can judge whether the injector is clogged by checking the injection effect of the injector. If the injection effect is uneven or the injection is insufficient, it means that the injector is clogged. At this time, the injector needs to be cleaned or replaced.

Use professional testing equipment: You can use professional testing equipment to detect whether the injector is clogged. This method is more accurate, but it requires professional equipment and technicians. It is recommended to go to a regular auto repair shop for testing and repair.

In addition, you can also check whether the injector is leaking, observe the engine start-up, check the amount of fuel injected by the injector, check the needle valve lifting movement of the injector, and check the needle valve seal of the injector to determine whether the injector is clogged. Symptoms of injector clogging include engine shaking, unstable idle speed, weak car, reduced power, louder engine noise, slight missing cylinder feeling when shifting at low speed, fuel consumption, unqualified exhaust gas, and engine fault light on.
