Abstract

A valve for use in an internal combustion engine (100) is provided. The valve includes a valve head. The valve head (138) includes a combustion face (140) configured to face a combustion chamber (110) of the internal combustion engine (100). The combustion face (140) includes an angular side portion (152). The combustion face (140) also includes a central recess portion (144) defining an inner diameter (Di) and an outer diameter (Do). The inner diameter (Di) and the outer diameter (Do) together define a depth (DR) of the central recess portion (144). The valve also includes a neck portion (166) configured to connect the valve head (138) with a valve stem (168) of the valve.
