Racing Car의 ECU 제어에 의한 가속성능 향상에 관한 연구

Abstract

The fuel injection amount and timing along with the ignition timing for the gasoline engine of a racingcar were adjusted using an electronic control unit (ECU), and the engine performance was evaluated throughan acceleration test. The fuel map for the fuel injection amount and ignition map for the ignition timingwere derived. Using the transient throttle control, the air–fuel ratio could be maintained at a constant valueeven in the case of a sudden throttle operation. In the flat shift, ignition blocking was more effective thanfuel blocking. In a 75 m acceleration test, the required duration without and with ECU control was 4.47 sand 3.99 s, respectively. Notably, the acceleration could be improved by approximately 10.7% when the ECUcontrol was implemented.
