Ultrasonic atomization of fuel supply system is based on a modification of the traditional advanced fuel supply system for motorcycle engine fuel supply system,according to the motorcycle operating state changing fuel supply,so as to enhance the motorcycle engine fuel economy,improve the engine emissions,is one of the current research directions in the field of energy saving of motorcycle engine.Aiming at the problems of high fuel consumption and excessive emission of exhaust gas in traditional motorcycle engine,the paper designs and develops a set of ultrasonic atomizing fuel supply system for the traditional motorcycle engine.Research papers from the first engine energy-saving technology,ultrasonic atomization technology and other aspects of ultrasonic atomization of fuel oil at home and abroad,and according to the working principle of ultrasonic atomization,Dayang motorcycle engine with DY125 as the research object,the superiority of the atomization of the fuel supply system from the engine intake system and fuel supply system of two aspects of ultrasonic,on the basis of the ultrasonic generator,ultrasonic atomization,atomization of the fuel supply system of shunt valve,fuel air mixer solar term and other important components using SolidWorks three-dimensional modeling software to design and draw engineering drawings.The simulation and analysis of air combustion mixer were carried out by ANSYS software.Finally,in order to verify the advanced ultrasonic atomization of the fuel supply system,build the test platform of motorcycle engine,combined with the design requirements of the production of ultrasonic atomization of the fuel supply system and the prototype,the prototype is installed in Dayang motorcycle engine DY125,motorcycle engine as a platform of ultrasonic atomization of the fuel supply system for experimental verification.In conclusion,ultrasonic atomization of fuel supply system on the one hand will be fully atomized gasoline atomization generator,the air-fuel mixture more uniform formation of the mixer,so as to improve the coefficient of excess air mixture and combustion efficiency,improve engine power and emission;on the other hand,according to different engine operating conditions,to provide the appropriate concentration of the mixed gas engine,reduce fuel consumption,improve fuel economy.
