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

    摘要： A homogenous charge compression ignition engine is operated by compressing a charge mixture of air, exhaust and fuel in a combustion chamber to an autoignition condition of the fuel. The engine 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 will be ready for another transition to a new combination of engine speed and load.

    摘要： A fuel injection control system and method for delivering multiple fuel injections to a cylinder of an engine during a fuel injection event based upon engine operating conditions, the control system including an electronic controller coupled to an electrically controlled fuel injector, and a plurality of sensors coupled to the controller for inputting certain signals representative of certain engine operating conditions of the engine, the controller being operable to output a fuel injection signal to the fuel injector to deliver a first, a second, and a third fuel shot to the cylinder during a fuel injection event based upon the sensor signals. The controller also delivers each of the multiple fuel injection shots within defined cylinder piston displacement parameters during a particular piston stroke, within defined fuel apportionment limits, and within defined delay limits between each respective fuel shot so as to control exhaust emissions.

    摘要： An apparatus and method for multi-mode fuel injection is disclosed. A sleeve is disposed about a fuel injector tip movable between a first and second position and wherein the sleeve is capable of impinging the fuel spray as it enters into the combustion chamber. By impinging the fuel spray, different spray profiles or plumes can be obtained allowing the fuel injector to inject in different modes, including homogenous charge compression ignition.
