Diesel Injector Fuel Injector 095000-6491 Denso Injector for John Deere

But the current situation (the cleanliness of the new oil is not enough, the pollution of the oil transmission equipment, the cleanliness of the fuel tank is poor, the corrosion and corrosion of the fuel pipe), improve the fuel filtration accuracy will reduce the service life of the filter element, but reduce the filtration accuracy and seriously affect the work of the fuel injection pump and the fuel injector. Under the balance, it is necessary to ensure the clean fuel input to the locomotive (input by high precision filter filter pre-filtration), fuel tank and locomotive fuel pipe system clean enough, at the same time, the filter accuracy of the fuel filter and coarse filter fixed in a high precision. It is recommended that the precision of crude fuel filter should be 20μm, that of non-electric injection fuel fine filter should be 10μm, and that of electric injection fuel fine filter should be 5μm. Before the fuel is fed into the large tank of the locomotive, the fuel is filtered by a filter with a filtration accuracy of 5μm, preferably with a dewatering device.

Different engine due to combustion chamber structure ‚ optimal economy and power performance ‚ should have different injection pressure. Such as 4125 eight engine oil pressure of 125 + 5 kg/cm "‚ 490 engine is 175 kg/cm". A certain structure of engine fuel injector spray oil pressure is determined by test ‚ too high or too low hazard are considerable. The harm of low injection pressure ‚ (1) low injection pressure ‚ not only adverse ‚ fuel atomization and reduce ‚ range makes it cannot throughout the chamber; Impact with compressed air mix ‚ leading to incomplete combustion, exhaust smoke and carbon deposition. (2) due to the injection pressure spring pressure reducing ‚ advance to spray oil nozzle needle valve in the needle valve body stuck in the open position.
