Abstract

método para atuação de válvula variável para provimento de potência positiva e frenagem de motor método de controle de transição entre potência positiva e travagem do motor ( e vice- versa) é divulgado. esta transição pode ser feita utilizando acionamento de válvula variável e travagem de dois tempos. o processo pode envolver três modos de operação do motor: potência positiva (isto é, ignição ou não-travagem), travagem do motor, e transição entre travagem do motor e potência positiva. os acionamentos da válvula de admissão e escape fornecidos por cada um dos diferentes modos de operação podem ser diferentes um do outro
