On December 14, 2024, the financial sector reported that the China National Intellectual Property Administration information showed that Chongqing Cummins Engine Co., Ltd. had obtained a patent entitled "a gas mixer and gas engine", with the authorization announcement number of CN 222141393 U and the application date of January 2024.
The patent abstract shows that the present utility model discloses a gas mixer and a gas engine, comprising a mixing chamber and a main gas chamber; The two ends of the mixing chamber are respectively equipped with an air inlet and a mixed gas outlet, which are connected to the interior of the mixing chamber to form an air flow channel; The main gas chamber is annular and located on the outer periphery of the mixing chamber. A first partition is provided between the inner walls of the two ends of the main gas chamber, which is used to divide the main gas chamber into an outer chamber and an inner chamber arranged radially. The first partition is uniformly provided with several first ventilation holes in the circumferential direction, which are used to connect the outer chamber and the inner chamber to form the main gas flow channel. The main gas inlet is located in the outer chamber, and the first partition is conical in shape. Its small diameter end is set towards the mixed gas outlet and leaves a first annular gap between it and the side wall of the mixing chamber, which serves as the main gas outlet of the main gas flow channel, connecting the inner chamber and the mixing chamber. This application improves the mixing uniformity and mixing speed of gas and air, thereby meeting the performance requirements of high-efficiency superchargers.
