Abstract： Aiming at increasingly serious problem of motor vehicle exhaust emission pollutants influences on the environment，the principle of ultrasonic high-frequency oscillation was used and the fuel was atomized into ultra fine particles in ultrasonic nebulizer，which is formed the uniform combustible mixture with the fresh air，According to the different speed and working conditions，regulating valve opening was adjusted，to achieve different air-fuel ratio，and then it can full combustion in the engine combustor. By ultrasonic atomizing fuel supply system test，reliable test results were obtained. The results indicate that，it can effectively reduce the carburetor motorcycle exhaust emissions of pollutants（HC、CO），and improve fuel economy，to achieve the requirements of energy saving and emission reduction.
