Abstract

motor de combustão interna. a presente matéria refere-se a uma montagem de eixo de comando para um motor de combustão interna para fornecer um momento de válvula variável de tipo mecânico. a montagem de eixo de comando (200) inclui uma montagem de faseamento mecânico (230) disposta adjacente a um dentre pelo menos um flange de admissão (220) e pelo menos um flange de escape (225). pelo menos um membro de massa pré-carregada (235) tem capacidade de realizar mudança de fase de pelo menos um dentre flange de admissão (220) e flange de escape (225) em relação à roda dentada acionada (205) dependendo da velocidade de rotação de montagem de eixo de comando (200). um membro de carga axial (245) pré-carregado na direção axial é disposto adjacente ao membro de massa (235) que exerce carga axial no mesmo. a presente matéria aprimora a mudança de tempo de abertura e fechamento das válvulas atendendo assim aos requisitos de admissão e escape em todas as velocidades de operação do motor.
