Beschreibung
Zusammenfassung:	An internal combustion engine for a vehicle is provided, having at least one cylinder with a first gas exchange inlet valve, a second gas exchange inlet valve, a first gas exchange outlet valve, a second gas exchange outlet valve, and a piston with a piston crown which has a plurality of valve seat pockets. In each case one valve seat pocket is provided for the first gas exchange inlet valve, the second gas exchange inlet valve, the first gas exchange outlet valve and the second gas exchange outlet valve, and the plurality of valve seat pockets have at least partially different depths. Alternatively, one valve seat pocket is provided for the first gas exchange inlet valve and the first gas exchange outlet valve, and no valve seat pocket is provided for the second gas exchange inlet valve and/or for the second gas exchange outlet valve.
