摘要：The invention relates to an internal combustion engine, in particular a spark-ignition engine, in particular of a motor vehicle, having a crankshaft, having at least oneworking cylinder (10) which, together with a piston and a cylinder head, forms acombustion chamber, and having a cylinder head which, with a side facing towards thecombustion chamber, defines a combustion chamber plane arranged perpendicular to acentral longitudinal axis of the working cylinder (10), wherein each working cylinder (10) isassigned in each case one inlet duct (12) with an inlet valve (13) which selectively connectsthe inlet duct (12) to the combustion chamber, an outlet duct (14) with an outlet valve(15) which selectively connects the outlet duct (14) to the combustion chamber, anignition device (16) which projects into the combustion chamber and a fuel injector (18)which projects into the combustion chamber, wherein a y direction (20) is aligned parallelto a longitudinal axis of the crankshaft, that is to say in the longitudinal direction of theinternal combustion engine, an x direction (22) is aligned perpendicular to the y direction(20) and parallel to the combustion chamber plane, that is to say in the transversedirection of the internal combustion engine, and a z direction (24) is aligned

perpendicular to the x direction (22) and to the y direction (20), wherein points ofintersection of respective central axes of the inlet valve (13) and of the outlet valve (15)with an x-y plane, which is spanned by the x direction (22) and the y direction (20) andwhich lies in the combustion chamber plane, are arranged diagonally opposite on a firstcombustion chamber diagonal (26) which lies in the combustion chamber plane, andpoints of intersection of respective central axes of the ignition device (16) and of the fuelinjector (18) with the x-y plane are arranged diagonally opposite on a second combustionchamber diagonal (28) which lies in the combustion chamber plane. Here, the fuel injector(18) is arranged in such a way that a longitudinal axis (30) of the fuel injector (18) enclosesan angle ß (32) of greater than 30˚ with the x-y plane, and an angle α (34) of less than 30˚with an x-z plane which is spanned by the x direction (22) and the z direction (24).
