New Crdi Fuel Diesel Injector 33800-4X400 Ejbr03902D for Hyundai KIA

Diodes are added to the output terminal and circuit of the injector to ensure that high-voltage induced electromotive force is generated when the injector is turned on and off to act as a freewheeling clamp to protect the internal chip from being damaged. The design can be successfully applied to the high-pressure common rail technology, which can not only improve the power and fuel economy of the direct injection diesel engine, but also improve the emission performance. This requires the common rail injector to have the characteristics of high-speed response,
And its high-speed response characteristics are realized through the special design of the solenoid valve. A drive circuit for a fuel injector of a high-pressure common-rail diesel engine comprises a lightning protection circuit, a high-frequency filter circuit, a high-side drive circuit, a low-side drive circuit, and a current acquisition feedback circuit. Fuel injector control is the core part of high pressure common rail diesel engine management system, the response speed of opening and closing of fuel injector directly determines the accuracy of fuel injection. The design can realize the circuit and control precision. Through the realization of fuel saving and precise control, the precise control has been successfully realized. Through the nozzle structure of the injector and the consistency of the cycle fuel injection volume, it is a typical application of the electronic controller on the diesel engine. It can realize Fuel injection optimization for diesel engines with different temperature and stress fields.
