    Abstract: The present disclosure provides piston, comprising: a skirt having an upper body portion; a crown formed at the upper body portion; and a piston bowl formed at the crown. The piston bowl includes a first combustion surface and a second combustion surface opposite the first combustion surface. Each of the first combustion surface and the second combustion surface are formed and positioned to accommodate inflowing injector spray so as to reduce heat transfer caused by impingements made by the inflowing injector spray.
