An exhaust manifold includes a first pipe for channeling a first portion of the engine exhaust and a second pipe for channeling a second portion of the engine exhaust. The first and second pipes are connected to an inlet of the turbine. A cross pipe, as part of an exhaust gas recirculation (EGR) conduit, is open between the first and second pipes and at one end to the remaining portion of the EGR conduit. A valve can be arranged within the cross pipe and ca be operable in a first mode of operation to block flow between the first and second pipes and allow flow between the first pipe and the remaining portion of the EGR conduit and to allow flow between the first and second pipes and the inlet of the turbine. The valve is operable in a second mode of operation to allow flow between the first and second pipes, and to reduce or block flow between the second pipe and the turbine inlet. | 02-18-2010 |
