Diesel Injector In diesel engines, the material that injects fuel into the inside of the cylinder is called an injector. Although all injectors work on the same principles, the separation of mechanical and hydraulic injectors has started with the addition of electronic systems.
Injectors capable of withstanding high fuel pressures inject the fuel into the cylinder side with a very high pressure and atomizing (in the form of particles). The side on which the injectors spray the fuels is called injector nozzle.
The injector nozzles may have a single orifice or up to seven orifices. The amount of bore can be increased, but the total bore diameter that may be on behalf of that injector is clear and the diameter of the sum of the boreholes gives it. On average, a single hole has a diameter of about twenty microns.
The structural characteristics of diesel injectors, the components found, the way they work vary according to the types of diesel injectors. The engine power is known by the state of the fuel being injected, and the state of the fuel injected varies depending on the amount of accelerator pedal depressed. The time of the injection process, ie the spraying process, is very importantly determined by the load of the engine. The timing of the injection process, ie the injection advance, is largely determined by the speed of the engine.
Diesel injector operating mechanisms
Injectors inject the fuel contained in both diesel and gasoline engines. The injectors in gasoline engines are known to be opened and closed directly by a solenoid. With the coil which is a solenoid, the injector needle can be moved, ie opening and closing operation can be performed.
This is because the fuel pressure is not too high. The injectors in diesel engines operate at a very high pressure, so they cannot be opened and closed directly with the aid of any solenoid (electromagnet), such as injectors of gasoline-powered engines; instead, the injectors can be switched on and off by making a difference in the fuel pressure contained in the injector, i.e. by using the pressure force of the fuel to give the injector needle the driving force. In this case, the solenoid is used to create the difference in pressure power of the electromagnet. With the help of a road between the control room and the pressure chamber.
How do injectors work?
The operation of the diesel injector is mainly based on the Pascal principle. A different amount of force is provided by varying the cross-sectional area of the upper end of the pressure transfer rod of the injectors and the cross-sectional area at the bottom of the needle of the injector.
