Abstract
PURPOSE: To provide a constantly fixed fuel injection pressure difference and precisely control an injection amount by providing a fuel injection valve between two orifices which are disposed in a bypass passage.
CONSTITUTION: A bypass passage 15 bypassing a throttle valve 14 runs aside a suction pipe 13 communicated with an engine 12 and contains an orifice 16 and a sonic orifice 17. A fuel injection valve 18 which is opened or closed by a control circuit 22 is disposed in the passage 15 between the orifices 16, 17. By opening the valve 18, a fuel of a certain pressure is injected into the passage 15 via a fuel pump 19 and a pressure regulator 20. Thereby, a pressure P2 in a line between the orifices 16, 17 is constantly different from a pressure P3 in the passage 15 and the resultant pressure difference is carried into the control circuit 22 to control the valve 18.
