<p>A turbine inlet arrangement for a turbocharger for an internal combustion engine having at least two cylinders, comprises a conduit connecting exhaust manifolds for gas from respective cylinders of the engine to an inlet opening (13) of a turbocharger turbine, the conduit comprising a pulse converter section (8) comprising two converter channels (2, 3) for exhaust gas each having a first end (4, 5) of relatively large cross sectional area and a second end of smaller cross sectional area (e.g. around 60-80 % smaller), each of the channels (2, 3) being arranged to taper smoothly along a section of its length, preferably a stabiliser section (10) comprising a channel of generally uniform cross-sectional area, and a diffuser section (12) having a cross-sectional area which increases in the direction of gas flow to the turbine inlet.</p> |
