The piston head comprises an asymmetrical piston cavity (7). A non-rotational symmetric elevation (8) extends in the interior of the piston cavity. Independent claims are also included for the following: (1) a method for manufacturing a gas Otto engine; and (2) a method for operating a gas Otto engine.",
