Development of New Electronically Controlled Fuel Injection System ECD-U2 for Diesel Engines 910252

To meet the 1990s' requirements for diesel engines, the realization of innovative fuel injection system has been expected. Thus the fuel injection system named ECD-U2 was newly developed. ECD-U2 is the electronic unit injector system with high pressure common rail of which features are explained as follows;
Fully electronic and flexible control in fuel quantity and injection timing. Adjustable injection rate shape Optimum injection pressure control Superior packageability and low drive torque loss.
In this paper, design strategies, actual hardware configurations and some test results of ECD-U2 are described.
