Auto Diesel fuel Injector Diesel Fuel Injector Nozzle L239PBC for Delphy BEBE4D13001 BEBE4D13101 Diesel Fuel Nozzle Diesel fuel Nozzles For diesel Engine, Diesel fuel nozzle actually is a simple solenoid valve, it can produce suction, drawn up the needle and open the spray holes when the solenoid coil is energized, the Fuel can high-speed spray throught the annular gap between the head of nozzle and needle shaft, to form a mist, which will help combustion.

Nozzle itself is a normally closed valve (normally closed valve means when there is no input control signal, the valve has been turned off; while the valve is normally open when there is no input control signal, the valve has been turned on by a down movement of the needle valve to control the valve opening and closing.) When the ECU issued a fuel injection command, the voltage signal causes the coil current flowing through the nozzle, nozzle the valve by the field generated, so that so that the fuel can be ejected from the nozzle hole when valve opens well. The biggest advantage is that jet fuel to the fuel supply control is very precise, so that the engine can have the correct air-fuel ratio in any state, not only keeping the engine running smoothly, but also be able to meet its emission norms of environmental regulations.

Mechanics of Diesel Fuel Injectors

Basic diesel fuel injectors contain a fuel supply line, an intake valve, an exhaust valve and the fuel injection apparatus. Each cylinder is attached to its own fuel supply line, all of which run from the fuel tank to the engine. Fuel is transferred through these fuel supply lines to the fuel injector device attached to each cylinder. Along the way, the fuel passes through a filter that removes residue and impurities. When the diesel fuel reaches the injector device, it becomes highly pressurized. The fuel injector is attached to a small pump, which forces air into the injector and pressurizes the diesel fuel. The injector then sprays the diesel fuel through a small nozzle into the cylinder's combustion chamber. The nozzle contains a series of small holes, which ensure even distribution of the diesel fuel into the cylinder's combustion chamber. An air intake valve sucks air into the chamber, which mixes with the vaporized diesel fuel and intensifies the combustion. An exhaust valve removes the resulting emissions from the combustion chamber, and a return fuel line removes any excess fuel from the combustion chamber and returns it to the fuel tank.
