A piston for an internal combustion engine, such as a high-pressure direct injection (HPDI) diesel/gas internal combustion engine. The piston has a piston recess, in particular an omega piston recess. The piston has a piston crown face which is provided so as to extend annularly about a centre axis (M) of the piston. The piston has a plurality of piston stages, which are provided so as to extend annularly about the centre axis (M) and which are arranged between the piston crown face and the piston recess. The piston geometry can lead to an increase of the degree of engine efficiency with a simultaneous reduction of the exhaust emissions.
