Abstract: A fuel injection control apparatus for engines used in vehicles, particularly, a golf-cart is disclosed. An engine 1 is operated by means of an accelerator pedal 15 and is assisted with its startup by a starter 7. An injector 17 is controlled to inject fuel pumped by a fuel pump 19 into an air-intake passage 2. A controller 40 controls the starter 7, the injector 17, and the fuel pump 19, and others. Upon depression of the accelerator pedal 15 to start up the engine 1, the controller 40 actuates the starter 7 and simultaneously actuates the injector 17 only one time for initial injection. Specifically, the controller 40 controls such that the initial injection and the ignition associated therewith are performed even if no pulse signal is input from a crank angle sensor 33.

Abstract: An automatic speed control apparatus for controlling the running speed of a vehicle at a constant set speed includes an auxiliary intake passage providing direct communication between portions of a main intake passage upstream and downstream from a throttle valve so as to bypass the throttle valve, an auxiliary intake air valve adapted for controlling the flow rate of air in the auxiliary intake passage, and a fuel supply cut-off means for suspending the supply of fuel to the engine from a moment at which a fuel supply cut-off condition is met, which requires the throttle valve to be set at the minimum opening position and the engine speed to be higher than a predetermined fuel supply cut-off engine speed, until the moment at which a predetermined fuel supply recovery condition is met. An actuator for actuating the throttle valve is controlled so as to vary the degree of opening degree of the throttle valve and enable the vehicle to run at the constant set speed.
