Abstract of the Disclosure A preheating system for a Diesel engine including a preheating plug energized through a glow relay, and a charging switch for deenergizing the glow relay when the charging switch detects a starting of the engine, comprises a glow switch adapted to be closed at a moment an engine key is inserted into an engine key switch, and a timer switch for exciting the glow relay for a determined period of time after the closing of the glow switch. The preheating system further comprises a second glow switch, a glow plug preheating circuit from the second glow switch through contacts of a relay having a self- holding circuit to the glow plug, and means for sensing an overheating of the glow plug and interrupting the glow plug preheating circuit. The system according to the invention remarkably facilitates a start of the Diesel engine without requiring a particularly intentional operation of a driver and reduce the time required for the preheating. The system is useful and durable in use and inexpensive to manufacture.
