  • Patent number: 10012153
    Abstract: A method for controlling an engine includes the steps of, in response to a transient operating event, determining a first amount of exhaust gas recirculation (EGR) that if provided to an intake of the engine would avoid turbocharger compressor surge in a turbocharger, determining a second amount of EGR that if provided to the intake would avoid turbocharger compressor choke in the turbocharger, and determining a third amount of EGR that if provided to the intake would avoid engine smoking, and adjusting EGR provided to the intake of the engine in accordance with the determined first, second, and third amounts.

  • Patent number: 9920715
    Abstract: Various methods and systems are provided for adjusting a flow of exhaust gas in an exhaust gas recirculation system. In one embodiment, a method for an engine comprises controlling a flow of exhaust gas through an exhaust gas recirculation system of an engine system based on a choke level of a turbocharger. For example, the flow of exhaust gas in the exhaust gas recirculation system may be reduced to within a threshold of a choke level of the turbocharger, in response to an ambient condition.

  • Patent number: 9422879
    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.

  • Publication number: 20160230712
    Abstract: Various methods for controlling EGR rate are disclosed. In one embodiment, a method comprises routing at least a portion of exhaust from a first exhaust manifold to an intake manifold, and not to atmosphere, the first exhaust manifold exclusively coupled to a first cylinder group. The method further includes routing exhaust from at least one additional exhaust manifold coupled to a corresponding at least one additional cylinder group to atmosphere, and during a first engine operating condition where an engine fuel demand is below a threshold demand, not injecting fuel to each of a subset of cylinders in the first cylinder group while injecting fuel to a subset of all cylinders coupled to the at least one additional exhaust manifold, where a number of cylinders of the subset of cylinders in the first cylinder group decreases in response to an increase in a target EGR rate.
