摘要： Methods and systems are provided for adjusting a location of a fuel injection in response to a substitution rate and a desired EGR flow. In one example, a method may include injecting a first fuel to a combustion chamber via a direct injector positioned to inject directly into the combustion chamber, injecting a second, different, fuel to the combustion chamber via an exhaust port injector positioned to inject toward an exhaust valve of the combustion chamber, and combusting the first and second fuels together in the combustion chamber.

摘要： A system is provided that includes a controller configured to determine one or more propulsion-generating vehicles in a group of propulsion-generating vehicles that have an increased risk for damage to an engine system based on operation at a fueling level that is less than a designated threshold fueling level for at least a designated time period. The controller is further configured to determine respective power outputs for the propulsion-generating vehicles in the group such that the one or more propulsion-generating vehicles having the increased risk for damage to the engine system do not operate below the designated threshold fueling level for longer than the designated time period.

摘要： Methods and systems are provided for a turbocharger. In one example, a method includes adjusting one or more of a wastegate position and a position of vanes with operation of a turbocharger to reach a desired turbocharger speed via a controller. The method further includes adjusting engine operating parameters to reach the desired turbocharger speed.

摘要： 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.
