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