ABSTRACT:
Upon the closing of the ignition circuit, this Diesel engine warm-up control system operates to establish a glow plug energizing circuit; to energize a "wait" indicator lamp and to produce a timed glow plug energization cycle signal. Upon the termination of this signal, the glow plug energizing circuit is maintained; the "wait" indicator lamp is deenergized and a "crank" indicator lamp is energized. The timed glow plug energization cycle signal is re-initiated upon engine crank to maintain the glow plugs energized for a controlled period of time after engine "start". A re-cycle feature which re-cycles the system in the event the engine does not start after crank, an automatic shutdown feature which deenergizes the glow plugs at the conclusion of the controlled period of time after the ignition circuit is closed in the event the engine is not cranked and a fast idle feature which provides engine fast idle during and for a predetermined time period after each cranking period at all engine temperatures are provided.
