Abstract
PURPOSE: To improve starting property of an internal combustion engine, by providing a timer circuit for controlling perheating of a thermostat by passing electric current to the thermostat for a time period required for cranking the engine and then stopping current supply in a preheating system of the engine.
CONSTITUTION: When a key switch 2 is turned to the preheating position, a transistor 12 conducts and a "preheating" indicating lamp 4 is lighted. In this state, when the voltage of a capacitor 6 is raised to a predetermined level, lamp 4 is turned OFF, thus indicating completion of preheating. Here, if the switch 2 is turned to the starter position, a capacitor 16 begins to discharge and current is supplied to a heater coil 3 of a thermostat since a power transistor 23 is in conduction. Afte passing of a certain time when the voltage of capacitor 16 is lowered by discharge, a transistor 21 is de-energized and current supply to heater coil 3 is stopped.
