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.
