Impact of Reduced Rotating Mass to Throttle Response in a CBR600F4i Engine 2005-01-3448

This paper examines the benefits of reducing the rotating mass in a Honda CBR600F4i engine to increase throttle response. Two engines, differing only in the amount of rotating and reciprocating mass, were built for testing. The engines were tested on a FSAE chase dynamometer to determine their individual throttle response, defined as the rate of increase of vehicle speed. As anticipated, the engine containing a lower amount of rotating and reciprocating mass produced a 21.5% faster throttle response.
