ENGINE MOVEMENT DETECTION SYSTEMS AND METHODS

摘要

A control system for an internal combustion engine is provided. The control system includes an engine movement module that selects from N engine rotation modes based on camshaft movement and crankshaft movement, where N is an integer greater than two, and where at least one of the N rotation modes is an assisted spinning mode. A diagnostic module enables one or more engine diagnostic modes based on the selected engine rotation mode.
