Abstract

Die Erfindung betrifft eine Brennkraftmaschine (1) mit mindestens einem Abgasturbolader (6), mit einer Ladeluftleitung (2), in welcher ein Ladeluftkühler (4) und eine Düse-Diffusoreinheit (3) angeordnet ist, und einer von einer Abgasleitung (7) abzweigenden Abgasrückführleitung (16), welche im Bereich einer Querschnittsverengung (17) in die Düse-Diffusoreinheit (3) einmündet, wobei die Düse-Diffusoreinheit (3) über einen ein Steuerorgan aufweisenden Hauptluftstrang (9) umgehbar ist. Zur Realisierung einer möglichst kompakten und raumsparenden Brennkraftmaschine (1) mit einer Düse-Diffusoreinheit (3) ist vorgesehen, daß die Längsachse (3a) der Düse-Diffusoreinheit (3) im wesentlichen parallel zur Kühlebene (4a) des Ladeluft-Kühlers (4) angeordnet ist.The invention relates to an internal combustion engine (1) with at least one exhaust gas turbocharger (6), with a charge air line (2), in which a charge air cooler (4) and a nozzle diffuser unit (3) is arranged, and one branching from an exhaust line (7) Exhaust gas recirculation line (16) which opens into the area of a cross-sectional constriction (17) in the nozzle diffuser unit (3), the nozzle diffuser unit (3) being circumventable via a main air duct (9) having a control element. In order to implement a compact and space-saving internal combustion engine (1) with a nozzle diffuser unit (3), it is provided that the longitudinal axis (3a) of the nozzle diffuser unit (3) is essentially parallel to the cooling plane (4a) of the charge air cooler (4) is arranged.
