Genuine new fuel injector valve assembly overhual kit F00RJ03288

(5) The fuel filter is blocked, resulting in supply shortage or interruption, self-extinguishing. (6) The piston pin is stuck with the connecting rod liner. (7) Diesel engine shaft burning and other failures. (8) The needle valve of the injector sticks and is stuck. (9) The fuel injection pump is not working normally, so that the oil supply is insufficient or no oil supply. (10) The fuel system enters the air, and produces "gas plug" in the oil circuit, so that the diesel engine oil supply is uneven, and the engine flares out when it is serious. (11) In the process of fuel storage and use, there is water into the fuel, if the water is more, easy to cause flame out. In short, the failure phenomenon of diesel engine is different due to different factors. Therefore, when the diesel engine is working normally, we should pay attention to observe the smoke exhaust condition, listen to whether there is abnormal sound in each part, touch the temperature of the diesel engine is too high, once abnormal occurs, we should check in time and make accurate diagnosis to prevent major accidents. In addition, in the use of the diesel engine to strengthen the maintenance and repair of various parts, in time to eliminate hidden trouble.

Common rail injector is the most critical and precise assembly in electronic control common rail system. With the improvement of modern diesel engine for the injection accuracy and response performance of common rail injector, it is necessary to optimize the structure and parameters of common rail injector constantly. The deep research on the working process of common rail injector is the basis of optimization, and its hydraulic process is one of the objects of study.
