Abstract

A method and device for controlling the heating of the glow plugs in a diesel engine, wherein the engine temperature is determined, independently of initialization of the engine control system and following a signal for starting the engine, by a sensor communicating with the glow control system. A glow command is generated if the engine temperature is below a predetermined value. Commencement of the heating procedure is automatically determined by the glow control system independently of initialization of the engine control system, and heating of the glow plugs can start prior to completion of initialization of the engine control system. The time required for the completion of initialization of the engine control system can be saved during heating of the glow plugs.
