Diesel Injector Fuel Injector 095000-6632 Denso Injector for Nissan Quan MD90 MD92 9.2D

The space at the front of the needle valve body is called the oil chamber, the oil chamber should be as small as possible, because the needle valve injection after the end of the seat, the fuel in the oil chamber due to high temperature expansion and evaporation, with a certain pressure, there is a part of the fuel into the combustion chamber, this part of the fuel it does not get good atomization, in time it is in late combustion, combustion is not complete, the result of diesel engine work black smoke. Harmful components such as carbon monoxide (CO), carbohydrogenated compounds (HC), nitrogen oxides (NOx) and particulates in the exhaust gas will seriously pollute the surrounding environment.

The power performance, economy, emission, noise, reliability and durability of diesel engine depend on the state of fuel injection into the combustion chamber, which is directly related to the type of fuel injector matching the combustion chamber of diesel engine.

The nozzle couple should be checked and screened item by item according to the requirements of technical indicators before use, which is conducive to the flow of the injector, the stability of the work and the service life.

The spray Angle can be changed by changing the Angle of the shaft needle of the nozzle. The general principle is: pay attention to the noise of the use of large spray horn; Pay attention to the power output of the use of 0° ~ 4° small spray Angle.

When using orifice nozzle, in order to make the fuel spray evenly into the combustion chamber space, the orifice nozzle should be used.
