Abstract (en)
[origin: WO2010142389A1] The invention relates to a piston (1) of a diesel internal combustion engine which piston is produced of a light-metal material, especially of aluminum or an aluminum alloy, and which comprises a piston top (2) that has a combustion bowl (4a) in the region of a piston crown (3). The exterior of the piston top (2) has a ring groove region (5) destined to accommodate piston rings, a piston skirt (6) being contiguous to said ring groove region and the piston skirt having diametrically opposed hub bores (7). In order to form a multiple omega-shaped combustion bowl (8), the bowl edge (10a) is surrounded by a radially interspaced rounded-off recess introduced in the piston crown (3).
