摘要： A method of controlling pre-primary ignitions of an internal combustion engine includes accessing data corresponding to an exhaust gas recirculation error and data corresponding to at least one of a rotational speed of the engine, a throttle position of a throttle, and a combustion mode of the engine. A voltage of the electrical power to be applied to an ignition source and a number of pre-primary ignitions to be applied are calculated based on the data corresponding to the exhaust gas recirculation error and the data corresponding to at least one of the rotational speed of the engine, the throttle position, and the combustion mode of the engine.

摘要： An internal combustion engine includes a combustion chamber defined by a cylinder bore in a cylinder block, a cylinder head and a piston. A groundless barrier discharge plasma igniter including an electrode is embedded in a casing fabricated from a dielectric material and is disposed in a mounting boss. The groundless barrier discharge plasma igniter has a tip portion that protrudes through an opening in the cylinder head into the combustion chamber. A controller having an electrical ground connection to the cylinder head is configured to apply a high frequency electrical pulse to the groundless barrier discharge plasma igniter. An electrical ground path is formed between the mounting boss and the cylinder head. A plurality of plasma discharge streamers is generated on the casing between the tip portion and the mounting boss when the controller applies the high frequency electrical pulse to the groundless barrier discharge plasma igniter.

摘要： An internal combustion engine includes a fuel injection system including a fuel injector disposed to inject fuel into the combustion chamber, and a plasma ignition system including a groundless barrier discharge plasma igniter that protrudes into the combustion chamber. A controller includes an executable instruction set to control the engine in a compression-ignition mode when the output torque request indicates a low load condition, including instructions to control a variable valve actuation system and control the plasma ignition system to execute plasma discharge events subsequent to controlling the fuel injection system to execute a fuel injection event, wherein the fuel injection event achieves a cylinder charge having a lean air/fuel ratio.
