The present study introduces a proposal to improve the longitudinal performance of a land vehicle through the adoption of an unusual traction control system. The system is capable of improving the transfer of engine power to the ground and reduces the complexity of the task being performed by the driver. High-performance vehicles are able to achieve high levels of longitudinal acceleration and, sometimes, the power excess leads to the spinoff of the drive wheels, which decrease the ability of the tires to generate force, and consequently the vehicle acceleration. The proposed system acts in addition with the motor control, through the derivation of the motor speed signal, and its control by comparison with a predefined value. The control can delay or even suppress the ignition of the engine. Thus, the rate at which the engine gains speed, and consequently, the rate at which the vehicle accelerates, is limited.

This work aims to study the selection of a heat exchanger available in the market with the objective of implementing it in a vehicle. The vehicle used for the tests was a prototype, developed by Formula UFMG team. It was made an experimental and a theoretical study in order to calculate the power of the CB600F engine to compare with the experimental study of heat dissipation of the selected heat exchanger. This comparison was made to check whether the heat exchanger reaches the vehicle’s requirements, and it has shown good convergence. The engine technical features were used in the theoretical studies, and thus the power was calculated. The experimental data were obtained by assembling the car in a roller dynamometer with the necessary instrumentation for these tests being performed. In these tests, the critical operation conditions of the vehicle were simulated, once the engine operates at a temperature of 95°C.

This paper describes a reverse engineering methodology to obtain a three-dimensional (3D) model of an internal geometry of an engine adapted with a torch ignition system. The reverse engineering methodology began with the measurement of the internal geometry from the cylinder head using silicon. Then, the obtained silicone molds were analyzed in a 3D scanner obtaining a cloud of points which was then treated in a commercial CAD software in order to generate de 3D computer model. The virtual geometry obtained was used to run CFD simulations with the torch ignition system. In order to increase the reliability of the results, a comparison between the pressures in the cylinder obtained numerically and experimentally were made. The same procedure was made in the pre-chamber, thus validating the model.
