ELECTRONIC ENGINE CONTROL MODULE INCORPORATING GLOW PLUG ANDGLOW PLUG LAMP CONTROL

摘要

The engine control module incorporates strategy which controls and modulates glow plug activation and also controls activation of a glow plug indicator lamp mounted in the cab of the vehicle. The control functions are separate in action but both are based on first sensing input power. If power is out of a predefined range strategy is provided for maintaining the glow plugs off. Both are secondly based on sensed engine coolant temperature, with out of range coolant temperatures causing activation of the glow plugs so long as input power is within range.
