Abstract
This work presents an analysis where the variation of the dimensions of the geometry of a combustion chamber of an internal combustion engine is evaluated. The analysis was conducted in such a way that the volume of the combustion chamber of the original engine was not altered, thus the piston diameter and stroke were varied, while maintaining a fixed displaced volume, comparing the results with the original xstroke/bore ratio. The idea of the work is to determine which contribution of loss is most significant for the internal combustion engine, whether it is thermal and friction losses, or fluid dynamic and inertial losses. At the end of the study, it was not possible to obtain any type of benefit in relation to the original stroke/bore ratio, and the highest average gains recorded per engine speed were not higher than 1%.
