An Optimization Design of Throttle Body for EFI Motorcycle Engine 2008-01-1537

This paper studied the optimization design of throttle body for electronic control motorcycle engine FY156FMI. It was studied the influence of the inner diameter, configuration of valve and its axis and inner configuration of the pipe of throttle body on the engine performance. The inner diameter of throttle body was designed on the basis of resonance theory. And the prototypes of throttle body designed were manufactured and tested by engine experiment. Results showed that the power of the engine applied with the throttle body, which has been optimization designed with a thinner throttle valve and a taper inlet port, and the size of inner diameter of throttle body increased from 26mm to 28mm and the thickness of the axis decreased, was improved effectively. The optimization throttle body can meet the design target.
