More Information
Summary:The invention discloses a steel piston structure of a heavy gas machine. A combustion chamber of the steel piston structure adopts a necking structure, and the combustion chamber comprises a throat arc, a bottom arc and a bottom center arc; the throat arc is arranged at the top of the combustion chamber; the upper part of the throat arc is connected with the top surface of a piston through a transition slope; the bottom arc is arranged below the throat arc, and the lower portion of the throat arc is connected with the upper portion of the bottom arc through a straight line; and the bottom center arc is arranged at the bottom of the combustion chamber and protrudes in the throat direction. The ratio of the throat diameter to the outer diameter of the piston is between 50% and 60%, and the ratio of the throat diameter to the maximum diameter of the combustion chamber is between 65% and 75%. According to the steel piston structure of the heavy gas machine, by adopting the necking structure, mixed gas can be full
