Intake System Design for a Formula SAE Application 2001-01-2553
A prototype engine intake design incorporating a required 20-millimeter restrictor is currently being evaluated for the 2001 Formula SAE competition. The engine is a 600 Honda CBR F4 four stroke. This carbureted stock engine was converted to fuel injection, requiring complete intake redesign. The primary difference from the stock intake design is the use of dual plenums, which prevents charging losses due to overlapping intake valve events. The throttle body and venturi design have also been improved. Preliminary test results are presented to validate design calculations and indicate potential for improvements.
