실차용 엔진 토크미터 개발 및 연비 인자 분석

The mechanical energy of engine is lost by engine friction and in driving the engine's auxiliary components, and then transmitted to transmission. Thus, it is very important to know the exact value of engine friction and the driving torque of engine's auxiliary components in order to reduce fuel consumption of engine by reducing these losses. And, it is also helpful to know the braking torque of engine in vehicle so as to improve vehicle's driving performance. For these reasons, present study developed engine torquemeter for in-vehicle application, and measured braking torque of engine in vehicle and analyzed fuel consumption contributions of engine's auxiliary components.
