Instrumentação Veicular para Testes de Emissões? Avaliação de um Servo-Freio Eletromecânico no Sistema de Frenagem Automotivo

Résumé

There are many studies for reducing fuel consumption and vehicles emissions as weight decrease of components as well as implementation of innovative, environmentally friendly technologies, as the usage of electromechanical brake booster vacuum-independent in braking system.It is essential to validate new technologies by collecting data on vehicles with precision and consistency.Test analysis can be done completely and significantly only if there is repeatability and accuracy in data collection.The proposal of this paper is to present the vehicle instrumentation for emission tests in the evaluation of the reduction of fuel consumption and CO2 emissions with the application of an electromechanical brake booster.The vehicle instrumentation enabled data collection: vehicle dynamics from CAN network, electrical system by vehicle battery, generator, and the product under investigation and, fuel consumption through a mass flow meter.The results showed reduction of fuel consumption and emissions without impacts neither electrical system nor vehicle performance. INTRODUÇÃODe acordo com a Organização Meteorológica Mundial, os níveis de dióxido de carbono (CO2) subiram para 413,2 partes por milhão em 2020.Apesar de ter ocorrido uma queda temporária dos índices durante os lockdowns causados pela pandemia de Covid-19, os resultados indicam um aumento maior do que a taxa média na última década.A taxa atual de aumento dos gases tem impacto direto no aquecimento global.Com a taxa atual os aumentos de temperatura estariam superiores à meta do Acordo de Paris que é de 1,5 graus Celsius acima da média pré-industrial para 2030 [1].
