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

Abstract

<div class="htmlview paragraph">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;</div> <div class="htmlview paragraph"> <div class="quote"> <div class="htmlview paragraph">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.</div> </div> </div> <div class="htmlview paragraph">In this paper, design strategies, actual hardware configurations and some test results of ECD-U2 are described.</div>
