Each unit of this product is assigned a 30-digit alphanumeric identification code, which corresponds to information about the individual characteristics of the injector. When installing a new injector, the code printed on its body is entered into the ECU using control and diagnostic equipment. Such individualization allows you to configure the control of injectors with the most successful set of ECU output parameters.
Operating principle
Fuel is supplied to the injector under high pressure. Significant mechanical force is required to open the spray valve.
Fuel pressure is used as the energy source to open the spray valve.
The injector has two cavities into which fuel is supplied under pressure. In these cavities, the fuel presses on special end surfaces of the control piston. The forces developed by the fuel on both sides are balanced. When a control signal is supplied to the winding, the electromagnet opens a special hole through which the fuel flows from the upper control chamber into the drain line. The balance of forces acting on the control piston is disturbed, and the piston, moving upward, opens the spray valve. After the signal is removed from the electromagnet, the chambers are restored, and the piston, under the action of the return spring, closes the spray valve.
