O presente trabalho foi realizado com o objetivo de se encontrar o combustível ideal para o Carro de Patrulha da PSP, tendo como pano de fundo a discussão pública acerca das vantagens das viaturas elétricas no que concerne às condições que oferecem em termos de economia e de emissões poluentes.
Foi abordada a importância do automóvel na sociedade, bem como do Carro de Patrulha no âmbito da missão da PSP no território nacional.
Indicaram-se os princípios básicos de funcionamento de um motor comum de automóvel no sentido de se perceber as condições de utilização dos diversos combustíveis de origem fóssil presentes no mercado. Paralelamente foi abordado o estado de arte de desenvolvimento tecnológico dos automóveis movidos total ou parcialmente a eletricidade.
Contextualizou-se a produção de eletricidade em Portugal, nomeadamente a importância que cada fonte de energia primária tem perante o cômputo energético global e disponível nas tomadas comuns da rede pública.
Como metodologia de estudo consideraram-se três parâmetros de análise entre duas viaturas similares, uma elétrica e uma a gasolina, nomeadamente comparação de valores de eficiência, de consumo e de emissões poluentes.
Verificou-se que as viaturas elétricas, no contexto atual da PSP, não são as mais adequadas.
The present work was carried out with the objective of finding the ideal fuel for the PSP Patrol Car, having as a background the public discussion about the advantages of electric vehicles in terms of the conditions they offer in terms of economy and pollutant emissions. The importance of the car in society was discussed, as well as the Patrol Car within the scop of PSP’s mission in the national territory. The basic principles for the operation of a common car engine were identified in order to understand the constiditions of use of the various fossil fuels on the market. At the same time, the state of the art of technological development of automobiles, totally or partially powered by electricity, was approached. The production of electricity in Portugal has been contextualized, namely the importances that each primary energy source has before the global energetic calculation and available in the common sockets of the public network. As a study methodology, three parameters were analyzed between two similar vehicles, one electric and other gasoline-powered, namely, comparison of efficiency, fuel consumption and pollutant emissions. It was verified that he electric vehicles, in the current context of the PSP, are not the most adequate.
