Beschreibung
Zusammenfassung:	PURPOSE: To improve mainly exhaust gas characteristics, in setting a controlled variable of an adjusting element which decides a recirculation rate of exhaust gas, by setting the amount of lift from a rotational speed and the amount of fuel, setting the controlled variable from the amount of lift, and correcting them according to the operational conditions. CONSTITUTION: The amount of fuel to be injected is set by an amount setting part 160 based on the respective output signal from an accelerator pedal position sensor 168 and another sensor 164. The amount signal is inputted into an amount controlling part 150, thereby being converted into a control signal for the second adjusting element 120. The amount of fuel supplied to an internal combustion engine 100 is adjusted according to the position of the second adjusting element 120. On the other hand, the amount signal is inputted into an exhaust gas recirculation controlling part 140, therefore the control signal for the first adjusting element 110 is calculated based on (injected amount of fuel), the amount of intake from, for example, an air flow meter 130, and an exhaust gas lambda value from a lambda sensor 135. The first adjusting element 110 controls the rate of exhaust gas to be recirculated to an intake duct.
