Hot Selling Diesel Fuel Injector 095000-8740 for Denso Diesel Injector Engine Spare Parts for Toyota Hilux

Injector is a diesel engine fuel supply system to achieve the important parts of fuel injection, its function is based on the characteristics of the diesel engine mixture formation, the fuel atomized into fine oil droplets, and will be sprayed to specific parts of the combustion chamber.

The injector should meet the requirements of different types of combustion chambers on the atomization characteristics. Generally speaking, the injection should have a certain penetration distance and spray cone angle, as well as good atomization quality, and no dripping occurs at the end of the injection.

The role of the injector is in the fuel pressure is constant, according to the engine ECU issued by the injection pulse signal, timed quantitative fuel injection intake manifold.

Automotive diesel engines are widely used closed injectors. This injector is mainly composed of injector body, regulator and injector nozzle and other parts. Closed injector nozzle is composed of needle valve and needle valve body of a pair of precision coupling, its clearance is only 0.002 ~ 0.004mm. for this reason, in the finishing process, but also need to be paired grinding, so in use can not be interchanged. General needle valve made of thermally stable high-speed steel, while the needle valve body is made of impact-resistant high-quality alloy steel.

According to the different structural form of the injector nozzle, the closed injector can be divided into two types of orifice injector and axial needle injector, which are used in different types of combustion chambers. The role of the injector is to inject fuel into the intake manifold at regular intervals under constant fuel pressure, according to the injection pulse signal from the engine ECU.
