Abstract (en)

[origin: US2018051650A1] A piston for a two-stroke engine operating with advanced scavenging has a piston base and a piston skirt. The piston has a piston pocket which has a smallest distance (e) from a top side of the piston base. The piston has a section plane perpendicularly to the longitudinal center axis of the piston, the distance of which section plane from the top side of the piston base is greater than the smallest distance (e). A middle plane of the piston intersects the piston skirt at a location. In the circumferential direction between the pocket and this location, a thickened area is arranged in the section plane, the greatest wall thickness of which area is at least 1.1 times the wall thickness at the location. The piston has an edge at a recess at which the piston skirt has a reduced height. A chamfer is arranged on the radially outer side of the piston.
