    摘要： An internal combustion engine with a vertically extending intake duct leading to the collecting portion of the intake manifold and a throttle valve in the intake duct has a main fuel injector and an auxiliary fuel injector arranged in the intake duct downstream of the throttle valve. An amount of fuel which is proportional to the amount of the sucked air is intermittently injected into the intake duct from the main fuel injector. At least a fixed small amount of fuel is in effect continuously injected from the auxiliary fuel injector, with additional amounts being temporarily supplied during engine startup and acceleration.

    摘要： A fuel supply system includes a pressure regulator (16) regulating the pressure of fuel supplied from a fuel pump (14). A valve device (18) is associated with the pressure regulator (16) for controlling the pressure of the fuel regulated by the pressure regulator (16). The valve device (18) supplies a part of the fuel as a control fluid to the pressure regulator (16). The part of the fuel supplied from the valve device (18) as the control fluid is not discharged into a fuel tank (12) when the pressure regulator (16) regulates the pressure of the fuel to have a higher value.

    摘要： A fuel injection apparatus has a delivery pipe 7, an injector 8, fixing hooks 56 and fixing hook grooves 38. The delivery pipe 7 has an electric signal line and a connector 34, the connector 34 being placed at an end of the electric signal line. The injector 8 has an O-ring 52 and an injector side terminal 54 and is mounted to the delivery pipe 7, the O-ring 52 having a center P and sealing a gap between the delivery pipe 7 and the injector 8. The injector side terminal 54 is electrically connected with the connector 34. The fixing hooks 56 and the fixing hook grooves 38 prevent the injector side terminal 54 from sliding with respect to the connector 34 in the direction of an axis of the injector 8. The contacting points between the fixing hooks 56 and the fixing hook grooves 38 are positioned on a line L. The line L passes through the center P of the O-ring 52 and is perpendicular to the axis of the injector 8.

    摘要： A fuel injector for an internal combustion engine includes a valve body which has a nozzle at one end. A stopper plate is located at the other end of the valve body and has a path for communicating between the upstream and the downstream sides of said stopper plate itself. A needle valve is slidably disposed in the valve body for opening and closing the nozzle. A lift stopper is fixed to the needle valve for limiting the stroke of the needle valve in association with the stopper plate and has at least one path for communicating between the upstream and downstream sides of the lift stopper itself. A first needle guide is fixed to the needle valve at the downstream side of the lift stopper and has at least one path for communicating the upstream and the downstream sides of the first needle guide itself. A second needle guide is fixed to the needle valve at the upstream side of the lift stopper and has at least one path for communicating the upstream and the downstream sides of the second needle guide itself. The second needle guide guides the needle valve so that the needle valve is correctly moved, along the center axis, in association with the first needle guide.

    摘要： An air-fuel ratio control system for an internal combustion engine which includes a carburetor in which the air-fuel ratio is set on the lean side rather than at a controlled air-fuel ratio. Fuel injection valves are provided for injecting additional fuel so that the air-fuel ratio is controlled to a correct value. A control circuit is provided for basically controlling the fuel injection rate in accordance with the RPM of the engine and the air intake pressure. The control circuit also corrects and controls the fuel injection rate in accordance with transient operating conditions of the engine.
