Abstract

A five-cylinder turbocharged internal combustion engine has an exhaust manifold (6-10) connected to a turbine housing (13). Four exhaust manifold conduits (7, 8, 9, 10) lead in pairs to the inlets (11, 12) of a twin-entry turbine (14). The fifth exhaust manifold conduit (6) is drawn past the turbine housing and opens into an exhaust pipe (18) on the downstream side of the turbine housing.
