RJ型汽车节油器又称螺旋搅拌节油器,安装在汽车化油器与进排气支管之间,通过一组螺旋叶片使混合气流在冲击下作旋转运动,从而改善油、气的混合状态,达到提高热效率、降低油耗的目的. 螺旋搅拌节油器由云南汽车厂曹振兴同志研制成功,经云南省交通科研所和交通部重庆 RJ-type automobile fuel economy, also known as screw-stirring fuel economy, is installed between the car carburetor and the intake and exhaust manifolds. Through a set of spiral blades, the mixed air flow is rotated under impact to improve the mixing of oil and gas. In order to improve the thermal efficiency and reduce the fuel consumption, the spiral-stirring economizer was successfully developed by Comrade Cao Zhenxing of Yunnan Automobile Factory, which was transported by the Yunnan Provincial Communications Research Institute and the Ministry of Communications in Chongqing.
