Abstract

Owing to highly developed industries and the use of fossil fuels, environmental problems becoming becoming pressing issues globally. Therefore, a study of automobile exhaust is urgently needed. Generally, air is sucked into the engine through the intake manifold. The aims of this study were to reduce the exhaust from used cars and increase the output by removing carbon deposits, which are considered a reason for the increasing exhaust and reduction of output, and the reduction of exhaust, variation of output and stability of idle speed were analyzed. The formation of carbon deposits within the suction manifold was investigated through a test device (KD147). In the intake manifold, the exhaust cleaning effect was confirmed.

산업이 고도로 발달함으로 인하여 화석연료의 사용이 많아짐으로 인하여 환경문제가 대두되고 있으며, 이에 자동차의 매연에 대한 연구가 필요하다. 일반적으로 공기는 흡기 매니폴드를 통하여 엔진에 흡입된다. 따라서 본 연구에서는 매연증가와 출력저하의 하나의 원인이 되는 카본 퇴적물을 세척하여 노후 된 자동차의 배출가스의 저감과 출력향상, 배기가스 저감량, 출력변화 그리고 공전속도의 안정성을 분석 검토하는데 그 목적이 있다. 흡기 매니폴드 내의 카본을 클리닝하였을 때의 자동차 매연의 발생정도를 검사장비(KD147)를 통하여 분석하였다. 흡기 매니폴드 클리닝으로 매연의 감소효과가 있음을 확인하였다.
