Abstract
The invention relates to a spark-ignition engine having direct fuel injection, the fuel injector (2) and the spark plug (3) being arranged centrally on the upper side of the combustion chamber (1). The fuel injector produces an asymmetrical injection volume, so that the electrodes of the spark plug (3) are not directly affected by liquid fuel. The electrodes are, however, situated in a region reached by evaporating fuel.
