| description | A system includes a controller that is configured to respond to engine load being at a designated engine load point by operating an engine with a lower exhaust gas recirculation (EGR) amount and a more advanced fuel injection timing than any other steady-state engine load point when EGR and fuel injection are enabled. The controller is further configured to respond to engine load being within a range of engine load points around the designated engine load point by increasing the EGR amount and retarding fuel injection timing as load increases and as load decreases away from the designated engine load point. This may result in decreased fuel consumption while maintaining emissions below designated levels. |
