Diesel Injector Fuel Injector 095000-6472 Denso Injector for John Deere, Dongfeng

(1) The injection pressure is too low, which will make the fuel atomization poor, and the nozzle is easy to deposit carbon and is not easy to start. This causes a decrease in injection pressure. When the needle valve is stuck when it is closed, or the nozzle hole is blocked, the injection pressure will increase. These are the main causes of the "knock" of the cylinder.

(2) Diesel engine operation is "unstable" Under normal circumstances, there are problems with diesel sprayers, such as plugging or poor atomization of the nozzle hole, and uneven fuel injection in each cylinder of the diesel engine. As a result, problems such as the diesel engine cylinder not igniting have caused the diesel engine to run unsteadily, and even difficulties in starting the diesel engine.

(3) Intermittent Flameout of Diesel Engine When the needle valve is stuck in the process of diesel engine operation, the diesel engine cylinder will stall or intermittently stall because there is no oil injection or insufficient fuel injection. In addition, if the diesel engine has multiple injector failures, the stability of the diesel engine operation will be greatly affected, and the degree of instability will increase.

(4) Black smoke from exhaust pipe, increased fuel consumption In many cases, due to the failure of the injector, diesel fuel combustion is not sufficient, and a large amount of black smoke emissions occur.

 The oil supply time is not accurate: the oil supply is too early, and the temperature and pressure problem occurs in the cylinder; The fuel supply is too late, resulting in a certain combustion of some diesel in the exhaust pipe; b. Fuel atomization is poor, and the fuel return oil path is blocked. Moreover, due to oil leakage, wear and blockage of the injection hole, etc., the injector has greatly aggravated the insufficient combustion of diesel, and the problems of increased fuel consumption and reduced power are very significant.
