Abstract: A homogeneous charge compression ignition engine (10, 110) 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 (29). This provides the engine controller (29) with a look up table of what compression ratio and exhaust gas rates should be at each speed and load. The engine controller (29) also balances at least one of combustion phasing and energy release among a plurality of cylinders (14) in order to enable higher load operation.

Abstract: A homogeneous charge compression ignition engine (10, 110) operates by injecting liquid fuel directly in a combustion chamber (14), and mixing the fuel with recirculated exhaust and fresh air through an auto ignition condition of the fuel. The engine (10, 110) includes at least one turbocharger (22, 23, 122, 123) for extracting energy from the engine exhaust and using that energy to boost intake pressure of recirculated exhaust gas and fresh air. Elevated proportions of exhaust gas recirculated to the engine (10, 110) are attained by throttling the fresh air inlet (17) supply. These elevated exhaust gas recirculation rates allow the HCCI engine (10, 110) to be operated at higher speeds and loads rendering the HCCI engine (10, 110) a more viable alternative to a conventional diesel engine (10, 110).

Abstract: A multi cylinder homogeneous charge compression ignition engine (10, 110) includes actuators (81, 16) and an engine controller configured to reduce variations in combustion phasing and/or combustion energy release among the different engine cylinders (14). By sensing both the phasing and magnitude of the combustion energy release, the engine controller (29) generates control signals to combustion phase controllers and combustion energy release controllers for the engine cylinders (14). The control signals may be different from one another to reduce variations across the group of engine cylinders (14). A combustion energy release controller may be a direct injection fuel injector (16), and the combustion phase controller may be a variable intake valve actuator (81). Reducing variations in these aspects of the combustion events, allows the engine (10, 110) to operate at higher speeds and loads.

Abstract: A homogenous charge compression ignition engine (10, 110) is operated by compressing a charge mixture of air, exhaust and fuel in a combustion chamber (14) to an autoignition condition of the fuel. The engine (10, 110) may facilitate a transition from a first combination of speed and load to a second combination of speed and load by changing the charge mixture and compression ratio. This may be accomplished in a consecutive engine cycle by adjusting both a fuel injector control signal and a variable valve control signal away from a nominal variable valve control signal. Thereafter in one or more subsequent engine cycles, more sluggish adjustments are made to at least one of a geometric compression ratio control signal and an exhaust gas recirculation control signal to allow the variable valve control signal to be readjusted back toward its nominal variable valve control signal setting. By readjusting the variable valve control signal back toward its nominal setting, the engine (10, 110) will be ready for another transition to a new combination of engine speed and load.
