Diesel Injector Fuel Injector 0445120398 compatible with Bosch injector ASHOK LEYLAND TRUCK/BUS

Improper injection advance Angle will increase the fuel consumption of diesel engine, leading to rough work, high combustion temperature, the thermal load of components to increase, and even a series of adverse consequences such as cylinder pulling, cylinder beating, piston ring breaking, pneumatic inversion, accelerating cylinder liner cavitation.

The fuel supplied to the locomotive diesel engine must be very clean, otherwise it will cause the plunger pair of the fuel injection pump and the needle valve pair of the fuel injector to strain, even stuck. Locomotive 16V240ZJB and 16V240ZJC diesel injection pump plunger pair is 0. 006 ~ 0. 008mm, very precise. At present, the filter precision of RC-30W crude fuel filter in locomotive is 76μm. The filter element of RJ-30Z fuel fine filter used in diesel engine is made of 50μm filter paper with star structure. They have a short service life, need frequent cleaning and replacement, increase the user's maintenance work and cost, and the filtration accuracy of the fuel is far enough to meet the requirements of the injection pump and injector. According to statistics, in each section of Shenyang Railway Bureau, hundreds of fuel injection pumps and injector couples are stuck in the water resistance test of locomotive diesel engine every year, which increases the test time and cost of diesel engine, and also affects the production schedule. At present, the electronic injection system has been used in new locomotive manufacturers. The electronic injection system has put forward higher requirements for fuel cleanliness. In order to ensure that enough clean fuel is provided to the fuel injection pump and injector, besides the development of efficient and long-life fuel filter, the cleanliness of the whole fuel system and the cleanliness of the fuel input to the locomotive must be comprehensively treated.
