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: A system for diagnosing engine braking performance of an engine comprising a plurality of cylinders comprises an exhaust manifold pressure sensor configured to detect an exhaust manifold pressure corresponding to exhaust gas emitted from a plurality of cylinders. A controller is configured to determine an exhaust manifold pressure value corresponding to at least one cylinder of the plurality of cylinders that is being used for engine braking, from an exhaust manifold pressure sensor signal received from the exhaust manifold pressure sensor. The controller is also configured to determine an engine braking value based on the exhaust manifold pressure value.

Abstract: A internal combustion engine system includes a gasoline internal combustion engine having a set of donor cylinders and a set of non-donor cylinders. The donor cylinders provide a proportion of the exhaust gas to an exhaust gas recirculation system and the remainder of the exhaust gas to an exhaust gas aftertreatment system including a particulate filter. The non-donor cylinders also provide exhaust gas to exhaust gas aftertreatment system. An engine controller can determine whether the particulate filter needs regeneration, and in response, retard a spark timing of the non-donor cylinders by an amount that is different from an amount or retardation of the donor cylinders.

Abstract: An internal combustion engine includes a number of cylinders and a controller operably connected to interpret operating parameters related to the operation of the number of cylinders. A cylinder torque adjustment for each cylinder is determined from the operating parameters to provide a torque balancing response that reduces noise, vibration and/or harshness in engine operation.
