PURPOSE:To prevent the deterioration of combustion performance mainly on highlands by permitting an engine to be kept in high revolution state by correcting the fuel injection amount towards reduction in the acceleration range frequently used in the traveling in the urban districts and suburbs. CONSTITUTION:A fuel injection amount correcting system B is provided for a fuel injection control system A equipped with an injection control means 13 for determining the fundamental injection amount on the basis of each output signal of an engine revolution speed detecting means 11 and an accelerating-pedal opening-degree detecting means 12. In said correcting system B, each output signal of a means 14 for calculating the variation speed DELTAalpha of the accelerator opening-degree signal alpha and a means 15 for generating the acceleration standard value DELTAalphax corresponding to the operation state is compared in a judging means 16, and acceleration state is judged, and the fuel injection amount is corrected by a correcting means 18 in accordance with the result of judgment and the output signal of an atmospheric-pressure detecting means 17. The fuel injection amount is reduction-controlled in the acceleration range frequently used in the traveling in the urban districts and suburbs. |
