Abstract

An internal combustion engine with spark ignition and a piston that includes a substantially U-shaped asymmetrical piston depression with a depression floor that tapers towards an edge of the piston and that changes in a continuously rising manner into a depression wall, and an expanding squeezing chamber, the arrangement being adapted to promoting a swirling rather than a turbulent flow of injected fuel.
