A Study on the Power Output and Exhaust Emission using the Fuel Vaporizing Device in Spark-Ignition Engine

기화혼합장치를 사용한 스파크 점화기관의 기관성능 및 배기성능에 관한 연구

The effect of the three types of fuel vaporizing device on the engine torque and exhaust emission was investigated. Among the three types of fuel vaporizing device designed for the experiments, a 88mm long device with mesh around the inside pipe showed stable lean mixture combustion up to 21:1 air-fuel ratio and reduced the exhaustion of CO and HC. Compared with the general trend in the decrease of engine torque it was observed that the decrease of engine torque in this lean mixture combustion with the new device was small.
