INTERNAL COMBUSTION ENGINE SWIRLING DEVICE

摘要

mechanical engineering; intake systems of internal combustion engines. SUBSTANCE: according to invention swirling device for internal combustion engine has housing made in form of volute with inlet and outlet guide cylindrical channel, and cover. Inner surface of cover is made in form of cone coaxial with outlet guide cylindrical channel. Inner side surface of housing and surface of cover cone form a clearance changing into outlet guide cylindrical channel. Thanks to it maximum efficiency of swirling of fresh charge is provided and stable swirl is maintained before beginning of combustion in cylinder. EFFECT: improved efficiency of fresh charge swirling before intake. 2 dwg
