Preparación de un motor yamaha 400cc y adaptación a un prototipo de fórmula SAE para la carrera de ingeniería automotriz de la ESPOCH.

Abstract

In the present work of titling, the preparation of an engine Yamaha 400cc and the adaptation to a prototype Formula SAE was carried out, in order to increase its power and know which preparation process was the most reliable, as well as determine the appropriate engine location and other components, developing a guide for the execution of these works. The preparation required verification of the constituent systems and engine components to determine its status, making the replacement of the defective elements and applying the methods of preparation, later, the comparison between the values of standard and prepared form was performed. After the preparatory work was carried out, the value of the cylinder capacity of 204,58cc was modified and then the obtaining of values with the help of a chassis dynamometer was performed with an increase in power from 6,6 kW to 6500 rpm and an increase in torque from 9,96 N.m to 6000 rpm, showing that processes applied were suitable for 400cc Yamaha engine. In terms of adaptation, the location of the engine in the rear of the chassis and other components was done, to complying with the regulations of the Formula SAE. Finally, the Yamaha 400cc engine was ready for further works related to the Formula SAE prototype, therefore, it can move into competencies raising the prestige of the ESPOCH Engineering Automotive.
