Abstract

Considering the current reality of small-displacement internal combustion engines, their supercharging is very little developed, mainly due to its currently low viability. Given this, in addition to a trend towards engine downsizing, there is a possibility of research into supercharging these, using electrically driven compressors, to improve the drivability and power of these means of transport, maintaining good efficiency and low fuel consumption.Based on this, this project is based on the design, with a theoretical basis, of a turbocharger with electrical drive for small displacement engines, consisting of a thermodynamic and fluid dynamic analysis through the creation of a one-dimensional simulation model for computational prediction of its operation. .After testing different project configurations using the one-dimensional model, a CAD geometry will be created to start CFD simulations using Ansys Fluent and analyze the compressor's operation. In addition, the validity of each of the simulations will be discussed and a prediction of how the manufacturing and validation of the project would be carried out.Therefore, through this development, it will be possible to deepen knowledge in the areas of thermodynamics, fluid mechanics, programming and, mainly, computational modeling for simulations.
