| Abstract;Demands for reducing exhaust emission and enhancing fuel economy have been increasing in accordance with growing concerns regarding global environmental issues. An electronically controlled fuel injection system which precisely controls the air-fuel ratio has been adopted to effectively meet the demands. Technologies for miniaturizing and achieving a high-efficiency system have been established for fuel injectors, the fuel pump and ECU (Electrical Control Unit). For the fuel injector, a spray form and magnetic circuit was optimized through computer simulation. As the result, a fuel injector with good installation ability for engine displacements ranging from 50cm'3' to 900cm'3' was realized. For the fuel pump, the maximized motor efficiency along with an optimized pump rotor shape reduced current consumption by 25%. For the ECU, the development of a circuit-integrated custom IC and the standardization of a housing achieved a compact, light, inexpensive design. (author abst.) |
