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 ).
