摘要： A fuel control apparatus of an engine comprises fuel control means for controlling fuel supply means so that an amount of fuel supplied to the engine corresponds to an intake pressure on the basis of a signal outputted from intake pressure detecting means for detecting the intake pressure of an intake passageway, intake resistance changing means for changing a resistance of the intake air flowing through the intake passageway correspondingly to the operating condition of the engine, and correction means for correcting a supply amount of the fuel to be controlled by the fuel control means when the resistance of the intake air flowing through the intake passageway is changed by the intake resistance changing means.

摘要： Fuel injection increasing timing occurs differently from the timing of changing an intake air flow and an exhaust gas flow, wherein the fuel injection quantity is controlled by a detected intake pressure and an engine which increases the fuel injection quantity at accelerating comprises a system for changing an exhaust gas glow of an exhaust system by a sequential turbo control and changing an intake air flow of an intake system by a dynamic effect of an intake air. The fuel supply is delayed by the fuel injection quantity increase at accelerating. This delay and pressure difference of intake air and exhaust gas by changing intake air flow and exhaust gas flow work together to prevent the air fuel ratio from fluctuating greatly, and a good engine combustion is maintained.
