Abstract

"PROCESSO PARA O CONTROLE DE ENCHIMENTO EM UM MOTOR DE COMBUSTãO". O processo para o controle de enchimento consiste em que através do controle dos momentos de fechamento (AS) de no mínimo uma válvula de descarga do respectivo cilindro e através de abertura (EÍ1) de no mínimo uma válvula de admissão, na região do ponto morto superior (OT) do êmbolo, provoca-se uma recondução interna de gás residual no cilindro, com expulsão temporária de gás residual perante a no mínimo uma válvula de admissão, e que dentro de uma troca de carga no cilindro, no mínimo em duas fases (EÍ1, ES1, EÍ2, ES2), separadas temporalmente uma da outra, pelo menos uma válvula de admissão é aberta. Esse processo otimiza o funcionamento do motor na fase de funcionamento à quente, sob o ponto de vista do consumo, da emissão de poluentes e do silêncio de funcionamento.
