가솔린 터보차저 엔진 벤틸레이션 시스템 개발

A wide variety of engine ventilation system concepts are used to circulate blow-by gases inside of engine for gasoline engines. For turbocharged gasoline engine, the complexity rises due to additional connection to turbocharger. One difficulty with engine ventilation is that many hardware concepts are possible and do exist in many Automotive companies and the industry does not seem to converge to one best practice regarding type of blow-by control devices and usage of fresh air. This research focus on the systematic comparison for specifications, system characteristics, advantages, and disadvantages of various ventilation system. The purpose of this study is to define important criteria necessary to meet system requirements and to decide the best system architecture of gasoline turbo engines. In order to decide optimal ventilation system for turbocharged gasoline engine, Pugh concept selection matrix is utilized to list the various concepts and evaluate them based on requirement.
