The Use of Computer Simulation for Development of a Four-Cylinder Race Engine

This paper presents the development of an ethanol fueled high performance engine for drag racing. Through the use of a specific software (AVL Boost) it was possible to model and simulate the performance of the engine being developed. The initial parameters required for modeling and the geometry of the various engine components were obtained by direct measurements and data from the literature. Model validation was achieved by comparing simulation results with data found in literature. After that, various engine configurations had been simulated, changing design parameters in order to optimize engine performance. The analysis of simulation results enabled the selection of different components to be manufactured or purchased in order to achieve a high-performance engine for use in drag race competition, with improved torque and power.
