Abstract: Various methods and systems are provided for adjusting an air-fuel ratio for combustion in an engine. In one embodiment, a method for an engine (e.g., a method for controlling an engine system) comprises responding to a sensed change in a load on the engine, or indications of engine knock or misfire, by one or more of: altering a speed of the engine, adjusting a fueling flow rate into at least one cylinder of the engine, and adjusting a position of a valve in a bypass passage configured to direct compressed intake air away from cylinders of the engine to obtain a determined air-fuel ratio; and thereby maintaining an air-fuel ratio in a determined range.

Abstract: A method involves comparing a determined operating parameter of an engine, with a predefined operating parameter. The method further involves controlling a fuel source and an ignition source of the engine so as to operate at least one engine cylinder in a skip fire mode for at least one cycle of a crank shaft when the determined operating parameter is greater than the predefined operating parameter. The controlling involves transitioning the fuel source from a normal mode to the skip fire mode for the at least one cycle of the crank shaft either before transitioning the ignition source from the normal mode to the skip fire mode or when the ignition source is operated in the normal mode.

Abstract: Various systems and method for controlling exhaust gas recirculation (EGR) in an internal combustion engine are provided. In one embodiment, a method includes injecting fuel to a subset of cylinders that includes less than all cylinders of a first cylinder group to obtain a target EGR rate. The first cylinder group provides exhaust gas through an exhaust gas recirculation (EGR) passage structure fluidly coupled between the first cylinder group and an intake passage structure. The method further includes injecting fuel to at least one cylinder of a second cylinder group. The second cylinder group provides substantially no exhaust gas through the EGR passage structure.
