Abstract: An internal combustion engine is operated in accordance with a Miller cycle. The engine includes a piston disposed in the engine cylinder and configured to reciprocate between a top dead center position and a bottom dead center position of the engine cylinder. An air intake valve is coupled to the cylinder. The air intake valve is closed when the piston is about the bottom dead center position in the engine cylinder. An exhaust valve is coupled to the engine cylinder. The exhaust valve is opened for a predetermined time period when the piston is about the bottom dead center position of the engine cylinder after closing the intake valve so as to exhaust a predetermined quantity of fresh charge from the engine cylinder via the exhaust valve.

Abstract: Various methods and systems are provided for regeneration of an exhaust gas recirculation cooler. One example method includes adjusting cooling of exhaust gas by an exhaust gas recirculation cooler to maintain a manifold air temperature during an idle condition of an engine. The method further includes initiating regeneration of the exhaust gas recirculation cooler during the idle condition when an effectivity of the exhaust gas recirculation cooler falls below a threshold effectivity prior to or during the idle condition.

Abstract: A method of operating an engine comprises introducing into a cylinder volume a non-compression-combustible fuel, such as natural gas, a compression-combustible fuel, such as diesel, and an oxidant and mixing the components for greater than about 275 microseconds, prior to compression combusting the compression-combustible fuel. The mixing may be done such that the two fuels are at least partially homogenized in the cylinder volume. By mixing, or premixing, the two fuels prior to combustion, the compression-combustible fuel is then simultaneously combusted via compression at multiple ignition points in the volume. The second, non-compression-combustible fuel is ignited in response to the combustion of the first fuel. An engine that enables the various methods is also disclosed.
