Abstract
A method includes combusting air within a plurality of cylinders of an internal combustion engine by injecting a fuel into the plurality of cylinders. The method further includes expanding a first portion of an exhaust gas generated from the plurality of combustion cylinders via a turbine. The method further includes controlling at least one of feeding a second portion of the exhaust gas via an exhaust channel bypassing the turbine; and recirculating a third portion of the exhaust gas to the plurality of combustion cylinders via a recirculation channel, as a function of an intake manifold air temperature and pressure at which the engine is operated.
