    Avaliação do ganho ambiental com o uso da bicicleta de carga na última milha - uma revisão sistemática da literatura
    (Universidade Federal de Goiás, 2023-09-22) Oliveira, Fernando Soares Ribeiro de; Guerrero, Cintia Isabel de Campos Roque; Andrade, Carlos Eduardo Sanches de; Andrade, Carlos Eduardo Sanches de; Souza, Alessandro de Santana Moreira de
    The continuous growth of cities entails the demand for the use of means of transport, both for passengers and cargo. In the last mile, conventional means of transport are used, which consume fossil fuels, but more and more people are looking for other transport alternatives that live better with the environment. An example is the transport by bicycles and cargo tricycles, which can be used as sustainable alternatives for transporting cargo in the last mile. This work aimed to apply a Systematic Literature Review on using these vehicles in the last mile to evaluate the environmental gain obtained. The PRISMA methodology was used, and it led to quantitative and qualitative results relevant to the theme. Ten published articles were selected, seeking to obtain the state of the art of these sustainable transport alternatives worldwide. The results showed that the use of bicycles and tricycles is successfully applied to small and medium-sized goods, food products, pharmaceuticals, and documents, among others, and has significantly contributed to the reduction of congestion, CO2, traffic accidents, and local pollutants, increasing the quality of life in cities. An analysis of the results and its application in Brazil was carried out, where the potential for use was found, but in need of improvements in cycle paths and implementation of pilot projects.

    Tecnologias aplicadas aos motores convencionais para redução da emissão de poluentes atmosféricos no setor de transportes
    (Universidade Federal de Goiás, 2024-12-11) Alcântara, Ana Flávia Rodrigues; Andrade, Carlos Eduardo Sanches de; Andrade, Carlos Eduardo Sanches de; Guerrero, Cintia Isabel de Campos Roque
    The automotive sector, one of the largest contributors to atmospheric pollutant emissions, faces a growing challenge in the search for more sustainable energy alternatives. This article addresses technological innovations in the development of vehicles with lower environmental impacts, focusing on solutions to reduce pollutant emissions. It analyzes motorization technologies, including high-efficiency internal combustion engines, and explores the growing role of renewable fuels, such as ethanol and biodiesel. The transition to electric vehicles is also discussed, highlighting its advantages in terms of reducing emissions, but also the limitations associated with charging infrastructure and battery production. The objective of this work is, therefore, to identify which technological improvements can be applied to conventional engines used in transportation systems in order to mitigate atmospheric pollutant emissions. The method adopted is an integrative bibliographic review of the literature found in the CAPES Journal Portal, the USP Journal Portal, Google Scholar and SCIELO. Technologies already used in conventional engines were studied: automotive catalysts, start-stop systems and diesel particle filters. Added to this are the impacts of the transition to a more sustainable automotive industry, with the use of biofuels and the encouragement of the use of electric vehicles.
