Abstract

A system for a multi-cylinder compression ignition engine includes a plurality of heaters, at least one heater per cylinder, with each heater configured to heat air introduced into a cylinder. Independent control of the heaters is provided on a cylinder-by-cylinder basis. A combustion parameter is determined for combustion in each cylinder of the engine, and control of the heater for that cylinder is based on the value of the combustion parameter for combustion in that cylinder. A method for influencing combustion in a multi-cylinder compression ignition engine, including determining a combustion parameter for combustion taking place in a cylinder of the engine and controlling a heater configured to heat air introduced into that cylinder, is also provided.

Adaptive individual-cylinder thermal state control using piston cooling for a GDCI engine

Patent Roth, Gregory T; Husted, Harry L; Sellnau, Mark C

A system for a multi-cylinder compression ignition engine includes a plurality of nozzles, at least one nozzle per cylinder, with each nozzle configured to spray oil onto the bottom side of a piston of the engine to cool that piston. Independent control of the oil spray from the nozzles is provided on a cylinder-by-cylinder basis. A combustion parameter is determined for combustion in each cylinder of the engine, and control of the oil spray onto the piston in that cylinder is based on the value of the combustion parameter for combustion in that cylinder.

Fast GDCI heated air intake system

Patent Sellnau, Mark C.

A GDCI engine control system includes a fast electric heater located within a pocket in a cylinder head. The pocket is in fluid communication with multiple intake ports. A heater control system includes a capacitor that is configured to provide a voltage that is greater than battery voltage to more quickly heat the intake air during a cold start. Subsequently a lower voltage can be supplied to the heater.

GDCI intake air temperature control system and method

Patent Moore, Wayne R.

A GDCI engine control system provides rapid heating of intake air to the combustion chamber when the engine is cold. The engine uses an intake air pathway that includes a compressor having a compressor inlet and a compressor outlet. A loop fluidly connects the compressor outlet to the compressor inlet. First and second valves are arranged in the loop and are arranged near the compressor outlet and the compressor inlet respectively. First and second passages converge at a first junction, and the first passage fluidly connects the first valve and the first junction. The second passage fluidly connects to themore »« less

Advanced engine management of individual cylinders for control of exhaust species

Patent Graves, Ronald L [Knoxville, TN]; West, Brian H [Knoxville, TN]; Huff, Shean P [Knoxville, TN]; ...

A method and system controls engine-out exhaust species of a combustion engine having a plurality of cylinders. The method typically includes various combinations of steps such as controlling combustion parameters in individual cylinders, grouping the individual cylinders into a lean set and a rich set of one or more cylinders, combusting the lean set in a lean combustion parameter condition having a lean air:fuel equivalence ratio, combusting the rich set in a rich combustion parameter condition having a rich air:fuel equivalence ratio, and adjusting the lean set and the rich set of one or more cylinders to generate net-lean combustion.more »« less

Cylinder To Cylinder Balancing Using Intake Valve Actuation

Patent Duffy, Kevin P [East Peoria, IL]; Kieser, Andrew J [Morton, IL]; Kilkenny, Jonathan P [Peoria, IL]

A method and apparatus for balancing a combustion phasing between a plurality of cylinders located in an engine. The method and apparatus includes a determining a combustion timing in each cylinder, establishing a baseline parameter for a desired combustion timing, and varying actuation of at least one of a plurality of intake valves, each intake valve being in fluid communication with a corresponding cylinder, such that the combustion timing in each cylinder is substantially equal to the desired combustion timing.
