Abstract

A combustion process for a reciprocating piston internal combustion engine with applied ignition and operating with hydrogen injection as well as an internal combustion engine capable of carrying out the process, in which the air is supplied independently of the hydrogen and an air ring rotating about the cylinder axis is produced which has a density increasing radially outwardly; the injection of the hydrogen into the air ring thereby takes place into the central area of the air ring while ignition takes place within the transition area between the central hydrogen core and the externally rotating air ring.
