DIVIDED EXHAUST MANIFOLD SYSTEM AND METHOD

摘要

A flow including air and exhaust gas is received at a boost pressure at a plurality of cylinders (103). Exhaust gas is expelled from a first subset of the plurality of cylinders (103) into a first divided exhaust manifold (103). Exhaust gas is expelled from a second subset of the plurality of cylinders into a second divided exhaust manifold (111). The first subset and the second subset are different. An exhaust gas recirculation (EGR) system receives at an EGR inlet (131 or 201 and 211) a part of the exhaust gas from the first divided exhaust manifold (109) and a part of the exhaust gas from the second divided exhaust manifold (111).
