| 发明名称 | Methods and systems for exhaust gas recirculation cooler regeneration | ||
| 摘要 | Various methods and systems are provided for regenerating an exhaust gas recirculation cooler. One example method includes, initiating an EGR cooler regeneration mode, wherein the EGR cooler regeneration mode comprises changing a fuel distribution of a donor cylinder group relative to a non-donor cylinder group of an engine, and increasing at least one of engine speed or load of the engine. | ||

| 主权项 | 1. A method, comprising: initiating an EGR cooler regeneration mode, wherein the EGR cooler regeneration mode comprises: changing a fuel distribution of a donor cylinder group relative to a non-donor cylinder group of an engine; andincreasing at least one of engine speed or load of the engine,wherein changing the fuel distribution comprises adjusting the fuel distribution to decrease a fuel injection quantity to one or more cylinders of the donor cylinder group from the non-donor cylinder group to decrease a temperature of the EGR cooler if the temperature of the EGR cooler is less than a threshold temperature. | ||
