Engine cylinder event fill-in (phylinder)

摘要

A fill-in apparatus for an engine that injects a pseudo cylinder signal when an ignition event is missing from a cylinder. The pseudo cylinder signal is injected if no ignition event occurs at an end of a time period designated for that cylinder. An algorithm can be used to determine an engine period, determine a cylinder time, determine a predictive window, and analyze the cylinder ignition event to see if the fill-in signal is needed.
