Abstract
Two stroke internal combustion engine control compensates for diagnosed cylinder misfire conditions characterized by improper combustion, during a cylinder combustion event, of an air/fuel mixture in an engine cylinder by learning a required number of cylinder combustion events to periodically be skipped to allow for removal of residual combustion elements from the cylinder following improper combustion therein, and by periodically postponing cylinder combustion over the learned number of events. The learned number of events may vary across engine cylinders, across engine operating conditions, and further may vary as a function of each cylinder's misfire propensity and severity over various engine operating conditions.
