Abstract
PURPOSE: To quicken the starting of an engine by energizing a heater of an internal combustion engine up to fixed temperature for a short time, and to improve the durability of the hearer by reducing power applied to the heater when the heater reaches fixed temperature.
CONSTITUTION: When a key which is switched on at a preheating location in order to assist the starting of an engine, electricity from a battery B passes through contacts a, c and is directly conducts to a heater H, and the heater H is given power greater than conventional devices and the temperature rises for a short time. When the temperature of the heater H reaches fixed value, resistance value increasing with the temperature rise is detected by means of a voltmeter V, an ammeter A and a detector D, a relay M1 is operated and the contact c is opened. Thus, voltage is applied to the heater H through resistance R1, and the power of the consumption of the heater H is lowered. If K.S is connected to a contact b when starting the engine, a contact d is closed by means of a relay M2, and fixed power is conducted to the heater H.
