Abstract: A method of operating an internal combustion engine includes the steps of: igniting a diesel fuel and air mixture in a combustion cylinder using spark ignition; sensing knock in the combustion cylinder; adjusting a spark timing and a fuel injection amount in the combustion cylinder dependent upon the sensed knock; and igniting the diesel fuel and air mixture in the combustion cylinder using compression ignition.

Abstract: An internal combustion engine includes a turbocharger having a turbine, a first set of combustion cylinders, and a second set of combustion cylinders. A first particulate trap is in fluid communication between the first set of combustion cylinders and the turbine. A second particulate trap is in fluid communication between the second set of combustion cylinders and the turbine.

Abstract: An internal combustion engine includes a first set of combustion cylinders and a second set of combustion cylinders. A first exhaust manifold is associated with the first set of combustion cylinders, and a second exhaust manifold is associated with the second set of combustion cylinders. A turbocharger includes a turbine which is fluidly coupled exclusively with the first exhaust manifold. An EGR system fluidly interconnects the second exhaust manifold and an intake manifold.

Abstract: An exhaust gas recirculation (EGR) system is provided for an internal combustion engine having a combustion air intake circuit, an exhaust manifold, and an exhaust circuit for communicating engine exhaust to the environment. The EGR system includes an air-to-gas EGR cooler, an air supply conduit for supplying inlet air to the EGR cooler, an EGR supply conduit for communicating exhaust from the exhaust circuit to the EGR cooler, and an EGR outlet conduit communicating cooled EGR from the EGR cooler to the intake circuit. The EGR system also includes a venturi unit in the exhaust circuit, and an air outlet conduit communicating heated air from the EGR cooler to the venturi unit. Flow of exhaust through the venturi creates a pressure which draws cooling air through the EGR cooler. A valve controls flow through the outlet conduit as a function of a sensed temperature in the intake circuit.
