소형 고속 SI 엔진에서 SCV의 연비저감 효과에 관한 연구 = A Study on the Decrease Fuel Consumption of SCV in a High Speed Small SI Engine

다국어 초록 (Multilingual Abstract)

As an engine has a wide range of RPM (3000~12000 RPM), variable control system is necessary in order to increase engine performance. SCV has been frequently referred to as a possible way to increase engine performance at low RPM. The purpose of this study is to investigate on the influence of SCV, specially at the range of lower revolution, in a high-speed small engine. Experiments were conducted on 4 Valves SOHC/air-cooling single cylinder engine and SCV shapes have been tested for swirl intensity, the performance of power, fuel consumption and emission. As a result, we find to use SCV range be below 5000 RPM which fuel consumption decreased 9%.
