Verfahren zum Verbessern einer HCCI-Verbrennungssteuerung bei leichter Last unter Verwendung einer Messung von Zylinderdrücken

摘要

A method for controlling an amount of fuel reforming in an internal combustion engine configured to selectively operate in a homogeneous charge compression-ignition combustion mode with an exhaust recompression strategy includes monitoring in-cylinder pressures during a current combustion cycle, utilizing the monitored in-cylinder pressures to project reforming required in a next combustion cycle, and controlling the next combustion cycle based on the projected reforming required in the next combustion cycle.
