How to clean Mitsubishi Pajero 09 injector?

When the nozzle is blocked, it can be dredged with a needle, and it should be carefully cleaned after dredging. The large plane of needle valve body is in poor contact with the plane of injector body, or the cylindrical surface of needle valve is seriously worn. If the large plane of needle valve body is in poor contact with the plane of injector body, chromium oxide can be coated on the flat plate for figure 8 grinding; If the cylindrical surface of the needle valve is seriously worn, the needle valve couples should be replaced in pairs. Precautions should be cleaned regularly. Failure to clean the nozzle for a long time or frequent cleaning will have adverse effects. As for the cleaning time, it depends on the condition of the car and the quality of fuel added at ordinary times. Generally speaking, it is recommended that most users clean it once every 20,000 ~ 30,000 km. The car is in good condition and the fuel quality can be extended to about 40,000 ~ 60,000 kilometers. The fuel injector is slightly blocked, and sometimes there will be such a fault: when the vehicle starts in first gear, the car will shake a little, and when it accelerates in high gear, this phenomenon will disappear again. Assuming that all kinds of sensors on the vehicle are working normally, the throttle valve has been cleaned 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 can usually be avoided. Slight gums can dissolve. Therefore, in daily driving, you should always run at high speed to reduce the possibility of carbon deposition. If the fuel injector is not cleaned for a long time, the blockage will be more serious when the gasoline quality is poor or the vehicle runs for a long time, resulting in poor fuel injection, poor fuel injection angle and atomization, poor engine performance at idle speed, acceleration or full load, reduced engine power, increased fuel consumption, aggravated emission pollution, and even made the engine unable to work. Therefore, the nozzle should be carefully cleaned and inspected regularly to ensure its good work.
