<P>PROBLEM TO BE SOLVED: To improve the responsiveness to a short time switching operation of a vehicle's throttle valve. <P>SOLUTION: With respect to a vehicle which has fuel injection valves 10, 11 respectively at the upstream and downstream of the throttle valve, a fuel injection control system 41 has a fuel injection calculating part 57 which calculates the fuel injection amounts of both the upstream fuel injection valve 10 and downstream fuel injection valve 11. When the vehicle is in the midst of acceleration, an additional injection calculating part 54 arranges to have additional injection made from the downstream fuel injection valve 11. Meanwhile, when the vehicle is under deceleration, a deceleration compensation calculating part 56 brings the downstream fuel injection valve 11 to reduce its injection quantity, or prohibit an additional injection. <P>COPYRIGHT: (C)2012,JPO&INPIT |
