摘要： Various methods and systems are provided for operating an internal combustion engine, the engine having a plurality of cylinders including one or more donor cylinders and one or more non-donor cylinders. In one example, a method includes, during an exhaust gas recirculation cooler heating mode, operating at least one of the donor cylinders at a cylinder load sufficient to increase an exhaust temperature for regenerating an exhaust gas recirculation cooler, and operating at least one of the non-donor cylinders in a low- or no-fuel mode.

摘要： Methods and systems are provided for operating an internal combustion engine having an exhaust system and a plurality of cylinders that utilize fuel and/or oil for combustion and engine lubrication purposes. In one example, a method comprises, while the engine is operating in a low-load mode or an idle mode, successively operating distinct subsets of said cylinders at a cylinder load sufficient to increase an exhaust temperature for burning unburned fuel and/or oil deposited in the cylinders or engine exhaust system. Herein, each successively operated subset comprises at least one but fewer than all of the plurality of cylinders, and the cylinders that are not currently being operated in a subset are operated in a low- or no-fuel mode.
