Abstract

potência positiva combinada e operação de desativação do cilindro com evento de válvula secundária.um motor de combustão interna compreende uma pluralidade de cilindros, incluindo pelo menos um cilindro desativável que tem pelo menos uma montagem de desativador operativamente conectada a pelo menos um trem de válvula para o cilindro desativável. em tal motor de combustão interna, um método para acionar as válvulas do motor compreende operar pelo menos um cilindro da pluralidade de ci-lindros para fornecer geração de potência positiva de acordo com as atuações da válvula principal e, adicionalmente, colocar a pelo menos uma montagem de desati-vador para um cilindro ativável do pelo menos um cilindro desativável em um estado de desativação. enquanto a pelo menos uma montagem de desativador para o ci-lindro desativável está no estado de desativação e enquanto o pelo menos um cilin-dro está operando para fornecer geração de potência positiva de acordo com as atu-ações da válvula principal, o método compreende ainda realizar pelo menos um evento de válvula secundária através de pelo menos uma válvula de motor para o cilindro desativável.
