摘要： A fuel supply apparatus is adapted to control a pump which discharges fuel from a tank to a fuel passage, thereby regulating the pressure of fuel to be supplied to an engine. The tank includes a plurality of storage chambers, in a specific one of which the pump is placed. A part of the fuel discharged to the fuel passage is returned to the specific storage chamber through a branch passage. A storage chamber other than the specific storage chamber is in communication with the branch passage through a communication passage. A jet pump is operated to transfer the fuel from the storage chamber other than the specific storage chamber to the specific storage chamber through the communication passage by the action of the fuel flowing through the branch passage. An electronic control unit (ECU) controls an electromagnetic valve disposed in the branch passage to regulate the quantity of return flow, thereby delivering the fuel in a quantity corresponding to a consumption quantity of fuel to be sequentially consumed in the engine, to the engine through the communication passage.

摘要： In an ignition device for an engine 1, a spark plug 14 is operated to emit sparks with respect to the fuel-air mixture, so that the fuel-air mixture is ignited. A protrusion 19 provided on a flywheel 6 mounted on a crankshaft 5 is revolved with the rotation of the crankshaft 5. A magnet pickup 21 detects the passage of the protrusion 19. When the protrusion 19 passes near the magnet pickup 21, the magnet pickup 21 outputs a detection signal, in a pulse manner, having a peak value in response to the passing speed of the protrusion. When the detection signal outputted from the magnet pickup 21 exceeds a predetermined threshold value, the electronic control unit (ECU) 18 operates to activate the spark plug 14 through an ignition coil 15 so that the ignition timing is advanced or delayed in accordance with the difference in rotational speed of the shaft 5, i.e., of the engine 1.

摘要： A variable venturi type carburetor having a suction piston adapted to be moved toward and away from an opposing wall of the intake barrel in response to a change in the intake air flow rate so as to change the area of the venturi portion. The carburetor has a throttle valve with a tube-formed fuel introduction port through which the space defined at both sides of the throttle valve are communicated with each other. The fuel introduction port is so arranged that its upstream side end opening facing the suction piston is directed toward the wall to which the fuel discharged from the main jet is attached when the opening degree of the throttle valve is small.

摘要： Disclosed herein is an improvement in a variable venturi carburetor for an internal combustion engine including a fuel discharging main nozzle arranged in a venturi portion and a suction piston arranged in an opposite side of the main nozzle for reciprocating in response to the variation of negative pressure of air induced to the engine generated at the venturi portion and varying an area of an induction passage of the venturi portion. The improvement includes that a fore-most end of the main nozzle is projected into the venturi portion and a fuel guide member is arranged at a lower portion of the projecting portion of the main nozzle. The fuel guide member serves to guide a flow of liquid fuel when the flow rate of air flowing through the venturi portion is low and the liquid fuel is discharged through the main nozzle.
