1. A piston for an internal combustion engine, the piston being configured to reciprocate along a centre axis of the piston during operation in an engine,
wherein the piston comprises a number of fuel directing surfaces arranged at a distance from a top surface of the piston measured along the centre axis,
each fuel directing surface being configured to direct a fuel spray sprayed onto the fuel directing surface,
and wherein the fuel directing surfaces are arranged with gaps between two adjacent fuel directing surfaces, wherein each fuel directing surface comprises a trailing edge, and wherein the gaps are formed in a circumferential direction between trailing edges of two adjacent fuel directing surfaces.
