Optimering av spjällhus för dragracing

by Andersson, Kristoffer

Abstract (Summary)
In this undergraduate thesis a throttle body designed for drag racing is investigated and evaluated. The throttle body governs the air flow to the internal combustion engine and is controlled by the throttle twist grip. The concept is developed by Emtes Engineering and within this undergraduate thesis it includes to design a throttle body with the concept for the motorcycle Suzuki Hayabusa. The standard mounted throttle body is suitable for normal usage and a wide power range. For drag racing the maximum power output is crucial and the standard mounted throttle body is a bottle-neck at WOT (Wide Open Throttle).Complete solutions for various functions are missing for the concept. This undergraduate thesis includes completing the concept with a returning mechanism, synchronisation arrangement and proper standard components. At the beginning of the task it also includes to establish a specification of requirements and DFMEA (Design Failure Mode Effects Analysis).The final design fulfils the specification of requirements. The throttle body is compact, simple to assemble and suited for small scale manufacturing. The symmetrical design simplifies the CNC-manufacturing (Computer Numerical Control) and thereby reduces the costs.Finally a test was carried out to compare the new throttle body with the standard mounted. The methodology turned out to be unsuitable and the testing of the throttle body was without results. Further testing with other methods is recommended but that will not be a part of this undergraduate thesis.
