ABSTRACT:
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.
