    摘要： An operation amount detecting unit 17 detects an operation amount of a throttle grip from a zero position. A basic throttle opening degree computing unit 18 computes a basic throttle opening degree corresponding to the operation amount. A throttle opening degree additional value computing unit 20 outputs as a target throttle opening degree a value obtained by adding the basic throttle opening degree with a throttle opening degree additional value corresponding to the operation amount when the operation of the throttle grip is performed within a small operation region corresponding to an idle operation. The throttle opening degree additional value computing unit 20 outputs as the target throttle opening degree the basic throttle opening degree when the operation of the throttle grip is performed without the small operation region.

    摘要： An engine control method, based on engine intake pressure, is operable to shorten a period from a start of cranking until a sequential fuel injection control is determined. Provisional and final stroke determinations are made for a plurality of cylinders from a synthetic manifold pressure waveform. The provisional stroke determination is made after a crankshaft is rotated 720 degrees after settlement of a crank reference position. The final stroke determination is made when the crankshaft rotates 1440 degrees after the provisional stroke determination. When the provisional stroke determination is made, fuel is injected into the cylinders based on a detected value of the engine intake pressure; and when the stroke determination is finally settled, the fuel injection and ignition of the engine are controlled based on the detected value of the engine intake pressure.

    摘要： When cranking starts by turning on a starter switch 14, the ignition timing is first corrected to a fixed value on a retard side. When an IACV 6 reaches a fully opened position, the ignition timing is corrected to the retard side once, and thereafter corrected to an advance side. The correction to the advance side is performed in accordance with a difference between the number of idling target steps and the current number of steps, and the amount of advance correction is reduced as the difference is reduced. Upon completion of the initialization of the IACV 6, the ignition timing correction amount is then restored to the initial value by increasing the amount of advance by a predetermined amount in a stepwise manner.

    摘要： A fuel injection control system provided with a throttle by wire (TBW) system detecting an operation condition of a throttle grip and controlling, via an actuator, a throttle valve. The control system detects the throttle valve opening and controls an injector. An increased quantity correction value is determined based upon of an output of a throttle valve opening sensor and an operation condition of the throttle grip. When an acceleration condition of a vehicle is detected according to the output of the throttle valve opening sensor, an increased quantity correction of fuel is performed. The increased quantity correction value is brought to an attenuation condition in which the increased quantity correction value is gradually decreased, or a stop condition in which the increased quantity correction value is made to zero, when the throttle grip is not in drive in an opening direction, even though an acceleration condition is detected.
