摘要： A method for operating an engine at idle that reduces NOx and controls smoke and hydrocarbon emissions. An idle delivery quantity of fuel is determined and divided into a first quantity of fuel and a second quantity of fuel in approximately equal quantities. During a compression stroke of an engine piston, the first quantity of fuel is injected into an engine cylinder. Adjusting at least one of timing and quantity of the injection of the first quantity of fuel reduces, at least in part, NOx emissions. At a timing angle of at least thirty degrees after the first quantity of fuel is injected and after the first quantity of fuel has been burned, there is an injection of the second quantity of fuel. Adjusting at least one of timing and quantity of the injection of the second quantity of fuel reduces, at least in part, smoke emissions.

摘要： A homogeneous charge compression ignition engine is set up by first identifying combinations of compression ratio and exhaust gas percentages for each speed and load across the engines operating range. These identified ratios and exhaust gas percentages can then be converted into geometric compression ratio controller settings and exhaust gas recirculation rate controller settings that are mapped against speed and load, and made available to the electronic engine controller. This provides the engine controller with a look up table of what compression ratio and exhaust gas rates should be at each speed and load. The engine controller also balances at least one of combustion phasing and energy release among a plurality of cylinders in order to enable higher load operation.

摘要： An HCCI engine has the ability to operate over a large load range by utilizing a lower cetane distillate diesel fuel to increase ignition delay. This permits more stable operation at high loads by avoidance of premature combustion before top dead center. During low load conditions, a portion of the engines cylinders are deactivated so that the remaining cylinders can operate at a pseudo higher load while the overall engine exhibits behavior typical of a relatively low load.
