Engine exhaust system

摘要

The exhaust gas system (1) for the internal combustion engine has a pipe bringing exhaust gas (5) to a turbine (2) for turbocharger. The expanded gas (6) passes through a section (3) with curved vanes (15) in the outlet from the turbine (13). The angle of the vanes increases from their leading edges (18) to their trailing edges (20) to promote swirl of exhaust gas entering e.g. a catalytic converter (4).
