Embodiment Construction
[0074] Aspects of the invention will now be described more fully. Like numbers refer to like elements throughout. Well-known functions or constructions are not necessarily described in detail for brevity and / or clarity.
[0075] figure 1 A perspective view of a two-stroke engine piston 1 according to some embodiments is shown. For the sake of brevity and clarity, the two-stroke engine piston 1 is referred to as "piston 1" in some places herein. Piston 1 includes a piston crown 3 . When the piston 1 is arranged in the engine cylinder, the piston top 3 is arranged facing the cylinder head of the engine cylinder of the two-stroke engine. The piston crown 3 is arranged to define a combustion chamber together with the cylinder walls of the engine cylinder. Thus, the piston crown 3 is arranged to be in contact with hot combustion gases during the power stroke of the engine comprising the piston 1 . Furthermore, the piston 1 comprises a cylindrical mantle surface 5 . The outer...
