The invention discloses an air/fuel gas mixing device of a gas engine, which comprises an intake manifold connected with a cylinder cover and forming an intake passage in front of an intake valve; one end of the gas branch pipe is connected with the gas injection valve, and the other end of the gas branch pipe extends into the gas inlet manifold; a rotational flow piece is arranged in the gas inlet channel, the rotational flow piece is connected with the gas branch pipe, and high-pressure gas ejected by the gas injection valve is guided into the rotational flow piece through the gas branch pipe and forms rotating mixed gas flow. The rotational flow piece is arranged in the gas inlet channel, by means of the rotational flow piece and injection energy in the high-pressure gas injection process, gas can rotate, air and mixed gas are driven to rotate and keep entering the air cylinder, the air/gas mixing uniformity is improved, the rotary mixed gas flow entering the air cylinder can enable gas in the upper layer,
