Abstract:
In order to optimize combustion in a four-stroke spark-ignition engine with direct fuel injection, the conditions of charge flow are improved by providing the top surface of each piston with two longitudinal guiding ribs located at a distance from each other and a cross-guiding rib running transversely thereto, thus providing an H-shaped configuration.
