System and method for controlling exhaust emissions and specific fuel consumption of an engiine

A system comprising:

• an engine comprising a plurality of combustion cylinders;
• a turbine coupled to the engine, and configured to expand a first portion of an exhaust gas generated from the plurality of combustion cylinders;
• an exhaust channel for feeding a second portion of the exhaust gas bypassing the turbine;
• a recirculation channel for recirculating a third portion of the exhaust gas to the plurality of combustion cylinders;
• and
• a control system configured to control at least one of:
• feed of the second portion of the exhaust gas via the exhaust channel;
• and
• recirculation of the 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.

A non-transitory computer readable medium encoded with a program, to enable a processor-based control unit to:

• control at least one of:
• feed of a first portion of an exhaust gas via an exhaust channel bypassing a turbine;
• and
• recirculation of a second 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 an engine is operated.
