Abstract

The control system establishes an engine warm-up protocol based, at least in part, on elapsed time from engine start. The control system provides a reduced reliance on engine temperature as a basis for determining an appropriate engine idle speed. The control system thus reduces the likelihood of unstable idling conditions when, for example, inadequate cooling water or extremely cold cooling water is being supplied to the engine.
