Abstract
In competitions like MotoStudent organized by MEF (Moto Engineering Foundation) it is common that the organizers provide for the teams components like engine, wheels and tires that are not possible to be manufactured by them. Without knowing detailed specification for the absence of the manual and with restrictions on modifications, the team needs to project for example the motorcycle’s exhaust system in an optimized way to win the competition. This system is the scope of this study, that aims to estimate internal dimensions of the engine through data of temperature collected in the exhaust tube wall. The work uses a LabView program to acquire the data and correlates two theories to make the estimative on the overlap period with the acquired data. The results obtained were of 5,89% for a 150 cc motorcycle and of 0,68% for a 250 cc in comparison with the manual’s values for the exhaust tube length.
