More Information
Summary:The utility model discloses a special piston of gas engine, its structure is that the piston combustion chamber appears for the basin, and the central point that the combustion chamber is located the piston body puts, and the combustion chamber diameter is 9 with the pressure scaling of the degree of depth: 1. The diameter of combustion chamber top firepower bank excircle is 100mm, the tip diameter of combustion chamber is 89mm, the height of combustion chamber bottom surface to top surface is 21.9mm, the combustion chamber is domatic to be 65 with contained angle piston body top surface water flat line, combustion chamber top surface face on earth adopts the transition of annular throat mode, and the domatic and arc length bottom surface changeover portion is 12.5mm. Bowl [shaped] combustion chamber can reduce to press scaling, reduces the marginal thickness of piston junk excircle simultaneously, relative increment the clearance between piston and the cylinder liner, avoid the engine emergence of knockings,
