This paper aimed to show the importance of using intercoolers in a supercharged vehicle, as well as comparing two different types of intercoolers, these being air-air type and air-water type, in view of the increasing use of supercharged engines, mainly due to the incessant pursuit of increased energy efficiency and decreased emission of pollutants by automakers and governments. By comparing three different supercharged engine configurations with different intercooler arrangements, it is shown how the presence of this equipment can contribute to engine performance. It also presents the design process of the two types of intercoolers mentioned, with the results and characteristics of each architecture being discussed. With the execution of this work, it was observed that an intercooler is essential to obtain better performance results in supercharged engines, besides the fact that an air-water intercooler allows the use of a much smaller heat exchange area and flow rate. However, it is a more complex heat exchanger and requires more care than an air-to-air intercooler.
