Patent ID: 7565237

Claim:
A control system for achieving desired in-cylinder conditions of a diesel engine, capable of multiple combustion modes, such as conventional diesel combustion and at least one alternate combustion mode, the engine having a turbocharger and an exhaust gas recirculation (EGR) loop, comprising: a desired torque map for receiving at least an rpm value and for providing a desired torque value based at least in part thereon; a desired system state map for receiving the desired torque value and for providing a set of desired system state values based at least in part thereon; a supervisory controller for receiving the rpm value, the desired system state values, and a set of measured or estimated current system state values, and for providing a selected combustion mode based at least in part thereon; wherein the measured or estimated system state values are at least one or more of the following measured or estimated values: the intake manifold pressure, the pressure between a high pressure throttle between the intake manifold and the compressor of the turbocharger, the exhaust manifold pressure, the compressor power, and a fresh air value; and a first controller for receiving the selected combustion mode and the desired system state values, and for determining a first set of actuator values based at least in part thereon.
