Abstract
Among all the mechanisms that make up a car, the engine deserves a special mention, since it is responsible for power generation and is through it that the vehicle will start your movement. Over time the design of this engine had to evolve considerably compared with the first cars manufactured in the history, because of the social and ecological requirements. In this way, is of fundamental importance that the automakers to evaluate the behavior of the engine in your whole operating range, and this evaluation can be done through different numerical models. The most widespread models for the simulation of these mechanisms are CFD models, zero-dimensional models and quasi-dimensional models. In this paper is shown a comparative analysis between experimental results and results obtained through simulations of internal combustion engines using quasi-dimensional and zero-dimensional models.
