Patent number: 6250079Abstract: A turbo-charged internal combustion engine with a twin-entry exhaust turbine and with a valve arrangement (20) disposed in the turbine housing (11). By means of the valve arrangement (20) the exhaust channels (9, 10) in the turbine housing can be short-circuited. The valve arrangement also functions as a waste-gate valve by virtue of the fact that its valve element (26), in one position, permits exhaust to by-pass the turbine housing through a shunt (18).Type: GrantFiled: June 14, 2000Date of Patent: June 26, 2001Assignee: AB VolvoInventors: Lennarth Zander, Ingemar Martinsson, Kent Giselmo
