<p>PURPOSE:To prevent danger due to the heat generation in the resistance of a glow plug circuit as well as low efficiency caused by the reduction of viscosity of fuel and lubricating oil by inserting a resistance into the viscous fluid passage of an engine, and providing a device for heating the resistance in responce to a signal when the engine temperature is less than a prescribed value. CONSTITUTION:A heat plug 20 is attached to a bracket 25 such that a dropping resistor 16 serving as a heat generating part is inserted into a fuel inlet passage 23. To the resistor 16 a current is conducted for a prescribed period of time and its heat is radiated after an ignition switch is turned On to cold-start an engine, so that the fuel upstream of an element 26 is heated during plus period to reduce the viscosity of the fuel. Accordingly, the viscoisty resistance of the fuel passing through the element 26 is reduced, and it is prevented that air bubbles are, in the case of the high viscosity of the fuel, produced within the fuel near the downstream of the element. Accordingly, fuel distribution in mixed gas is made uniform to provided its good combustion, the properties of the cold starting of an engine are imrpoved, and it is made possible to prevent the exhaust properties from being deteriorated and to improve the fuel cost.</p> |
