Abstract: A method includes operating a spark ignition engine and flowing low pressure exhaust gas recirculation (EGR) from an exhaust to an inlet of the spark ignition engine. The method includes interpreting a parameter affecting an operation of the spark ignition engine, and determining a knock index value in response to the parameter. The method further includes reducing a likelihood of engine knock in response to the knock index value exceeding a knock threshold value.

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 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 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: Systems and methods for implementing regeneration of an aftertreatment component using exhaust gas recirculation is described. According to various embodiments, an engine system comprises an engine, a turbocharger, a fluid control valve, and a lean NOx catalyst. The engine has a first set cylinders fluidly coupled to an intake manifold and a second set of cylinders having fluidly isolated from the intake manifold of the engine. The fluid control valve is disposed between the first exhaust outlet and the exhaust conduit and is structured to selectively fluidly couple the first exhaust outlet to the exhaust conduit. Also, the lean NOx catalyst has an inlet structured to receive exhaust gases from the exhaust conduit at a position downstream of the turbine outlet and the fluid control valve.

Abstract: A method for energy ignition management of a spark-ignition engine includes receiving, by a controller, at least one ignition energy characteristic to affect control of at least one combustion cylinder. The method further includes controlling the at least one combustion cylinder via the controller. Controlling the at least one combustion cylinder via the controller includes adjusting the at least one ignition energy characteristic in response to at least one operating condition of the engine. The at least one ignition energy characteristic is a magnitude of one of a current or voltage of spark energy.

Abstract: A system includes an internal combustion engine having a number of cylinders. At least one of the cylinders is a primary EGR cylinder that solely provides EGR flow during at least some operating conditions. Operation of the primary EGR cylinder is controlled separately from the other cylinders to reduce internal residuals in the primary EGR cylinder.
