Abstract
motor de combustão com comando de válvula eletro-hidráulico e processo para o motor de combustão. a presente invenção refere-se a um motor de combustão (4) com comando de válvula (1) eletro-hidráulico para acionamento com curso variável de uma válvula trocada de gás (3), sendo que a válvula hidráulica (15) é ativada por um meio de ativação (16) eletrônico de tal forma que especialmente, durante a fase de partida a frio do motor de combustão (4) seja ajustado um curso de troca de válvula de gás (19) necessário para a troca de carga dentro de uma altura de curso mínima (h-min) e um momento de fechamento máximo (<244>-max). também é proposto um processo para operar um motor de combustão (4).
