DOI:
https://doi.org/10.47820/recima21.v6i2.6124Palavras-chave:
Controle de comando de válvulas, Motor de ignição por centelha, Ciclo Otto, Ciclo MillerResumo
O texto discute as diferenças entre os ciclos Otto e Miller em motores de combustão interna, destacando como o ciclo Miller, ao retardar o fechamento das válvulas de admissão, melhora a eficiência térmica ao permitir um fluxo reverso que reduz o trabalho de compressão. O desenvolvimento de tecnologias com controle eletrônico tem sido crucial para aumentar a eficiência energética e reduzir emissões de gases de efeito estufa, especialmente em setores como mobilidade e indústria. A revisão sistemática proposta visa analisar as tecnologias aplicadas nos motores Otto e Miller, identificando suas vantagens e desvantagens, e acompanhando a evolução das máquinas térmicas. O trabalho busca alinhar-se com os Objetivos de Desenvolvimento Sustentável da ONU, promovendo motores mais eficientes e contribuindo para a redução das emissões. O foco principal é catalogar as inovações em controle de válvulas em motores de ignição por centelha, avaliando suas aplicações e impactos.
