Abstract
An engine preheating system preheats an engine such as a diesel engine efficiently and quickly with heating members such as self-temperature-controlling glow plugs. When the engine is to be preheated quickly, a voltage to be applied to the heating members is increased by electric energy stored in a capacitor capacitors, and a large current is supplied to the heating members to preheat the engine in a short period of time.
