Abstract

In order to provide a mixture-compressing two-stroke Otto engine with fuel injection into the cylinder space, in which it is in particular intended to make a homogeneous mixture formation possible, it is proposed that the combustion space (19) possesses essentially the configuration of a hemisphere and, with its combustion space axis (21), is, from the cylinder axis (20) relative to the side of the cylinder (11) located opposite the exhaust duct (14), disposed so as to be offset, the injection nozzle being disposed relative to the combustion space (19 in such a way that the upper portion of the jet cone (22) penetrates a predominant volume proportion of the combustion space (19), while the lower portion of the jet cone extends underneath the cylinder bottom plane (25) approximately obliquely to the cylinder axis (20), but outside the combustion space (19).
