New Injector Nozzle Dlla139p2229 0433172229 for Fuel Injector 0445110418

The fuel injector plays an important role in the fuel supply system of the diesel engine, and its working capacity is directly related to the running stability, power performance, fuel saving and environmental protection ability of the diesel engine. With the continuous upgrading of modern mechanical technology, the technical system of diesel engines is becoming more and more reasonable, especially the application of digital electronic control technology has greatly improved the working performance of diesel engine oil supply system. In daily use, the fuel injector is one of the most frequently worked parts, and its working quality and service life are affected by many external factors. Only by correctly understanding the precautions for the use of diesel engine fuel injectors can it be beneficial to ensure that the diesel engine operates in good condition. Operate under the state of fuel injection, so as to exert the best performance and maintain a good service life.
The fuel injector of a diesel engine is a combination of mechanical and electrical control components, and its working process is controlled by electrical technology. Normally, when there is no electrical control signal input, the fuel injector is in a normally closed state. When the electrical system controls the electromagnetic coil When energized, the magnetic field generated by the electromagnetic coil will generate suction to the needle valve. After the needle valve is sucked up, the nozzle hole of the fuel injector will be opened, and diesel will be ejected from the nozzle hole quickly under the action of high pressure. Due to the position design of the nozzle hole It has a ring structure, and the sprayed oil mist is in the form of a uniform mist, thus ensuring the sufficient combustion of the diesel engine. The fuel injectors of modern diesel engines are all controlled by ECU, which can ensure the accuracy of fuel injection timing and fuel injection volume, and maintain the correct air-fuel ratio of the diesel engine system, which is conducive to the continuous and stable operation of the diesel engine and has good emission and environmental protection.
