Piston

The utility model relates to a piston. The piston is provided with a combustion chamber cavity (26) and a cooling channel (19) which at least partially surrounds the combustion chamber cavity (26), and an average first wall thickness (w31) of a first wall (31) arranged between the combustion chamber...

Summary:The utility model relates to a piston. The piston is provided with a combustion chamber cavity (26) and a cooling channel (19) which at least partially surrounds the combustion chamber cavity (26), and an average first wall thickness (w31) of a first wall (31) arranged between the combustion chamber cavity (26) and the cooling channel (19) is greater than 5% of a piston diameter (d8) of the piston (8). As a result, the extraction of heat by the cooling oil can be further reduced in the region of the combustion chamber pocket. This results in an additional increase in combustion chamber surface temperature and thus in thermodynamic efficiency. 本实用新型涉及一种活塞。所述活塞设有燃烧室凹腔(26)和至少部分区段地围绕所述燃烧室凹腔(26)环绕的冷却通道(19)，其中，设置在所述燃烧室凹腔(26)和所述冷却通道(19)之间的第一壁(31)的平均的第一壁厚(w31)大于所述活塞(8)的活塞直径(d8)的5％。由此，在燃烧室凹腔的区域中可以进一步减少通过冷却油对热量的引出。这导致燃烧室表面温度的额外增加并且因此导致热力学效率的额外增加。
