Abstract

motor de combustão interna do tipo de ignição a centelhas. tem-se provisão de um motor de combustão interna contendo um mecanismo de taxa de compressão variável que pode alterar uma taxa de compressão mecânica (a) e um mecanismo de sincronização de válvula variável (b) que pode controlar uma sincronização de fechamento de uma válvula de ingresso (7). efetua-se o cálculo de um ponto operacional pretendido que possa ser atingido após o transcurso de um tempo fixo sem entrada nas regiões sem-entrada (x1,x2) a partir do ponto operacional atual em sentido ao ponto operacional vindo a atender a demanda de quantidade de ar de ingresso voltado a um ponto operacional mostrando a combinação da taxa de compressão mecânica e da sincronização de fechamento da válvula de ingresso quando da alteração da demana da quantidade de ar de ingresso, efetuando-se as alterações na taxa de compressão mecânica e na sincronização de fechamento da válvula de ingressos em sentido a este ponto operacional pretendido.
