PURPOSE:To stop an engine automatically when warming-up is finished by connecting in series a make contact which opens when cooling water temperature reaches a specified value and a break contact which makes the circuit ineffective when warming up is finished and connecting said circuit with an ignition switch in parellel. CONSTITUTION:When an ignition switch 1 is turned on and an engine is started 6, the engine enters a warming up state and a negative pressure switch 3 is turned on by the suction negative pressure of the engine when the engine reached an idling revolution number. Therefore, a current flows passing battery 7 negative pressure switch 2 temperature switch 3 reverse flow preventing diode D1 engine ignition system 5 and vehicle electrical equipment 4 earth and the engine continues the starting state even if an ignition key is pulled off the key groove. When the temperature of engine cooling water rises as warmed up and reaches a specified value, the temperature switch 2 is turned off, the engine ignition system 5 is cut out and the engine stops. |
