Abstract: Natural gas engines have features of clean combustion, high heat load, low mechanical load, difficult lubrication and easy wear. The designing of a natural gas engine piston involving in piston head, ring zone, ring groove, pin hole are described in details in this paper. Test verification and FEA are carried out on natural gas engine pistons.
