Orientador: Sergio Santos Mühlen / Dissertação (mestrado profissional) - Universidade Estadual de Campinas, Faculdade de Engenharia Mecânica / Made available in DSpace on 2018-08-18T19:10:57Z (GMT). No. of bitstreams: 1 Hernandes_MarceloRocha_M.pdf: 3294457 bytes, checksum: d5c6210ad1c775f02c1a394d65ab908c (MD5) Previous issue date: 2011 / Resumo: A questão da partida a frio de motores movidos a Diesel ainda é um problema que não foi apropriadamente resolvido e se torna particularmente crítico em face da tendência de redução de níveis de emissões de poluentes a baixas temperaturas e da taxa de compressão do motor visando redução do consumo de combustível. Embora esteja claro que existem alguns fatores-chave que levam a um apropriado processo de partida a frio, sua relevância e relações não são claramente compreendidas. Assim, os esforços para a otimização do processo de partida a frio são principalmente baseados em procedimentos de tentativa e erro em câmaras climáticas a baixas temperaturas, com sérias limitações em termos de confiabilidade da medição em algumas condições, baixa repetibilidade e altos custos com experimentos. O objetivo deste trabalho é estudar os componentes auxiliares de partida a frio dos motores a Diesel com o intuito de adquirir conhecimento sobre este tema para aplicação em propulsores, de maneira que estes possam ser utilizados em regiões com temperaturas negativas com desempenho confiável. Os componentes estudados serão apresentados, bem como sua aplicação e importância na tarefa de proporcionar as condições adequadas à partida a frio do motor. Além disso, uma visão geral será dada em relação à contribuição que estes componentes trazem na redução de emissões de poluentes e consumo de combustível / Abstract: Cold start in Diesel engines is a problem which has not yet been properly solved and becomes particularly critical with the current trend to reduce the emission levels at low temperatures and engine compression ratio addressed to fuel consumption decrease. Although it is clear that there are some key factors whose control leads to a proper cold start process, their individual relevance and relations are not clearly understood. Thereby, the efforts on optimization of the cold start process are mainly based on a trial-and-error procedure in climatic chambers at low ambient temperature, with serious limitations in terms of measurement reliability, low repeatability and high experiments costs. The objective of this work is to study cold start auxiliary components of Diesel engines in order to acquire knowledge on this topic for application in engines in a way that they can be used in regions with low temperatures with reliable performance. The components studied will be presented, as well as its application and importance of providing appropriate conditions to engine cold start. In addition, an overview will be given on the contribution that these components are going to bring in the reduction of emissions and fuel consumption / Mestrado / Eletrônica / Mestre em Engenharia Automobilistica
