The present invention relates to an internal combustion engine (1) having a control apparatus (C). An air-fuel mixture with a combustion air ratio (), which may be adjusted by the control apparatus, is burned within the internal combustion engine. The control apparatus (C) comprises: a power output control circuit which adjusts a lambda value () to control the actual output (P_g) of the internal combustion engine (1) to be a reference power output (P(^d_g)) of the internal combustion engine (1); and an NOx discharge control circuit controlled through a functional relation (2) to operate an actuator, which influences the air supply pressure as an alternative parameter for NOx discharge, by air supply pressure to set an air supply pressure reference value (p(^d_im)) for each reference power output (P(^d_g)) of the internal combustion engine. The present invention is to provide an internal combustion engine having a control apparatus, which is able to observe a target value in relation to NOx discharge, to prevent shortcomings, and to specifically have proper transient behavior. 조절 장치(C)를 갖는 내연기관(1)으로서, 조절 장치에 의해 조정 가능한 연소 공기비(λ)를 갖는 공기-연료 혼합물이 내연기관 내에서 연소되고, 조절 장치(C)는 - 람다값(λ)을 조정하여 내연기관(1)의 실제 출력(P)을 내연기관(1)의 기준 파워 출력(P)으로 조절하도록 구성된 파워 출력 조절 회로, 및 - 급기 압력 기준값(p)이 내연기관의 각각의 기준 파워 출력(P)에 대해 설정될 수 있도록, NOx 배출에 대한 대체 파라미터로서 급기 압력에 영향을 미치는 액추에이터를 급기 압력에 의해 작동시키기 위해 함수관계(2)를 통해 조절되는 NOx 배출 조절 회로를 포함하는 내연기관(1)이 개시된다.
