Abstract

PURPOSE: To supply uniform mixture to an engine even under an operation condition that the negative pressure of a Venturi is low, by heating fuel intermittently injected by means of a magnet valve and by changing fuel into vapor under the condition that the negative pressure of the Venturi is low.
CONSTITUTION: An angle of revolution of a crank-shaft detected by means of a detector 10 for the angles of revolution and the pressure of an intake manifold 16 detected by means of an intake pressure sensor 9 are checked by means of an electrical control circuit 11, and time limit pulses corresponding to the operation conditions of an engine are transmitted to a magnet valve 7. Fuel measured by means of the magnet valve 7 is injected to a Venturi portion 4 from a nozzle 44. Fuel injected is converted into vapor by heating a PTC heater 15 by means of a power source control circuit 11a under an operation condition that the negative pressure of a Venturi is low. The heating of the PTC heater 15 becomes unnecessary because a heating plate 13 turns fuel liquid-drops into vapor by exhaust heat when the warming-up of the engine is completed.
