Phase detection system for internal combustion engine comprises injection cut-out by verifying or rejecting assumed phase angle at start using position derived from misfire detection

摘要

The method involves starting the engine with an unknown phase angle by assuming a phase angle, cutting out a number of injections at one or more cylinders, verifying or rejecting the assumed phase angle at the start using the position derived from the misfire detection and maintaining operation of an engine if the angle is rejected using doubled ignition output or re-synchronization.
