Brennkraftmaschine mit Saugmodul

Die vorliegende Erfindung betrifft eine Brennkraftmaschine (1) mit einem Motorblock (2), der mehrere Zylinder (3) enthält, mit einem Zylinderkopf (6), der am Motorblock (2) befestigt ist und zu den Zylindern (3) führende Frischluftkanäle (7) enthält, und mit einem Saugmodul (9), das am Zylinderkopf (6) befestigt ist und das eine Frischlufteinlassöffnung (10) sowie mehrere, mit den Frischluftkanälen (7) fluidisch verbundene Frischluftauslassöffnungen (11) aufweist. Eine vereinfachte Montage ergibt sich, wenn eine Ausrichteinrichtung (20) zum Ausrichten des Saugmoduls (9) relativ zum Zylinderkopf (6) beim Anbauen des Saugmoduls (9) am Zylinderkopf (6) vorgesehen ist. An internal combustion engine may include at least one engine block having a plurality of cylinders and at least one flange component. At least one attachment part may be secured to the at least one flange component. An alignment device may be constructed and arranged to align the at least one attachment part relative to the at least one flange component when the at least one attachment part is attached to the at least one flange component. The alignment device may include at least a first alignment unit, a second alignment unit, and a third alignment unit, which may be spaced apart from one another. At least one of the first alignment unit, the second alignment unit, and the third alignment unit may be constructed and arranged to align the at least one attachment part to a cylinder head in relation to a first aligning direction perpendicular to an attaching direction, when the at least one attachment part is attached to the cylinder head. At least one of the first alignment unit, the second alignment unit, and the third alignment unit may be constructed and arranged to align the at least one attachment part to the cylinder head in relation to a second aligning direction perpendicular to the attaching direction and inclined to the first aligning direction. The at least first alignment unit, the second alignment unit, and the third alignment unit may each be constructed and arranged to align the at least one attachment part to the cylinder head exclusively in one of the first aligning direction or the second aligning direction.
