Abstract: One embodiment is a system comprising an engine including a dedicated EGR cylinder configured to provide EGR to the engine via an EGR loop, a non-dedicated cylinder, a plurality of injectors structured to inject fuel into the dedicated EGR cylinder and the non-dedicated EGR cylinder, and an electronic control system operatively coupled with the fueling system and the ignition system. The electronic control system is configured to evaluate engine operating parameters including an engine load and an engine speed. The electronic control system is responsive to variation of the engine operating parameters to control operation of the fueling system to vary combustion in the at least one dedicated cylinder between rich of stoichiometric and stoichiometric.

Abstract: Systems, devices, and method are disclosed for differentially cooling an internal combustion engine. A cooling system includes a first cooling circuit configured to lower a temperature of a cooling fluid to a first temperature where the first cooling circuit is configured to dispense a first portion of the cooling fluid to cylinder walls and non-cylinder or non-combustion surfaces of the engine. The cooling system also includes a second cooling circuit configured to lower the temperature of a remaining or second portion of the cooling fluid to a second temperature that is lower than the first temperature where the second cooling circuit is configured to dispense the remaining portion of the cooling fluid to cylinder or combustion surfaces within one or more cylinders of the internal combustion engine.

Abstract: A system and method of inducing an operational response change in an operating direct-injection internal combustion engine is provided such that the engine includes a cylinder into which liquid fuel injection is directly performed. The method starts by operating the direct-injection engine using a start of injection (SOI) protocol. At some point during operation, it is determined that a change is desired for a first parameter of engine operation that is at least partially a function of a charge provided to the cylinder (such as the torque output). In response an operational response in the engine is induced by altering the SOI protocol via a first SOI alteration that alters the volumetric efficiency of the cylinder and changes the first parameter.

Abstract: A system and method are disclosed for controlling an engine using pre-chamber ignition. According to at least one aspect of the present disclosure, the system includes a pre-chamber ignition system in communication with a combustion cylinder of the engine. The ignition system includes a pre-chamber having a pre-chamber injector, an igniter, and a pre-chamber port structured to introduce a purge gas into the pre-chamber. The system further includes an exhaust gas recirculation system to dilute a main charge introduced into the cylinder. The ignition system improves engine efficiency and lowers emissions.
