The engine comprises a multi-cylinder direct-injection engine, the engine operative in repetitive cycles each cycle comprising intake, compression, expansion, and exhaust strokes. The method comprises adapting a plurality of fuel injectors to directly inject a first and a second mass of fuel into the cylinders during each cycle.

Abstract: Exhaust gas temperature is increased to improve the effectiveness of an after-treatment system having an activation temperature by deactivating one or more engine cylinders to increase the exhaust gas temperature from the remaining cylinders (during acceleration) or to decreasing exhaust gas flow rate (during deceleration or idling). In the system of the invention, a controller effects the deactivation and reactivation of cylinders and/or decrease and increase of exhaust gas flow in response to one or more sensors providing input of exhaust gas temperature or information from which exhaust gas temperature can be approximated. By achieving and maintaining the activation temperature, the present invention improves the effectiveness of after-treatment devices thereby lowering regulated emissions to desired levels.

Abstract: An internal combustion engine is equipped with an EGR system that includes an EGR heat exchanger. A method for monitoring the EGR heat exchanger includes monitoring an EGR gas inlet temperature to the EGR heat exchanger, an EGR gas outlet temperature from the EGR heat exchanger, a coolant temperature and a mass EGR flowrate through the EGR heat exchanger for a present engine operating point. An actual thermal effectiveness of the EGR heat exchanger for the present engine operating point is determined. A maximum heat transfer coefficient for the EGR side of the EGR heat exchanger is determined for the present engine operating point. The EGR heat exchanger is regenerated when the actual heat transfer coefficient differs from the maximum heat transfer coefficient for the present engine operating point.

Abstract: A vehicular heat exchanger processes a exhaust gas recirculation flow. A method to manage combustion by-product contaminant deposits within the heat exchanger includes repeatedly cycling a flow control device controlling the exhaust gas recirculation flow through the heat exchanger from an original position to an intermediate position and back to the original position. The original position is determined based upon a required exhaust gas recirculation flow into an intake manifold.
