Cyclic Dispersion in the Homogeneous-Charge Spark-Ignition Engine—A Literature Survey 810020

This literature survey was undertaken to assess the state of the art relative to cyclic dispersion in combustion and its effect on the subsequent pressure development in the cylinder of a homogeneous-charge spark-ignition engine. The scope of this survey ranges from papers written about 25 years ago, corresponding to the beginning of systematic investigations of this phenomenon, to more recent papers. The earlier papers described survey-type experiments in which controllable engine and operating variables were changed, generally one at a time. More recent papers have dealt with the relations between in-cylinder flows, and cyclic combustion and pressure variations. In this survey, these papers are reviewed and the findings are summarized.
