Abstract: 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 the loop at a second junction arranged fluidly between the first and second valves. An intake air heat exchanger is arranged in the first passage and fluidly between the first valve and the first junction.

Abstract: A GDCI engine recirculates exhaust gases to a combustion chamber using desired early injection parameters for a steady state engine operation from a controller. An engine control system detects a load increase relative to the steady state engine operation, and insufficient recirculated exhaust gases to the combustion chamber are delivered in response to the detected load increase as a result of transport delays. A last fuel injection into the combustion chamber during an engine cycle with multiple fuel injections is delayed as compared to the steady state engine operation. Combustion phasing within the combustion chamber is retarded in response to the delayed injection.

Abstract: A GDCI engine control system includes a heated catalyst in an engine exhaust port that is in close proximity to a combustion chamber and is used to heat rebreathed exhaust gases. The engine more quickly reaches operating temperatures, and emissions are reduced during cold running.

Abstract: A cylinder deactivation system includes an intake cam follower assembly, an exhaust cam follower assembly, an exhaust cam, and a controller. The intake cam follower assembly is used to open an intake engine valve and is switchable to operate in one of an active state and a deactive state. The exhaust cam follower assembly is used to open an exhaust engine valve and is switchable to operate in one of a primary lift state and a secondary lift state. The exhaust cam includes a primary lift cam lobe and a secondary lift cam lobe and is used to actuate the exhaust cam follower assembly in the primary lift state and in the secondary lift state. The controller is used to open the exhaust engine valve during the deactive combustion cycle in advance of the opening of the intake engine valve that occurs during the subsequent active combustion cycle.
