Abstract

"SISTEMA DE ATUAçãO DE VáLVULA PARA UM MOTOR DE COMBUSTãO INTERNA". A presente invenção é direcionada a um sistema de atuação de válvula para um motor de combustão interna. O sistema de atuação de válvula adicionalmente inclui uma montagem de atuação de válvula de admissão para operar pelo menos uma válvula de admissão em resposta a um came de admissão. O sistema de atuação de válvula adicionalmente inclui uma montagem de atuação de válvula de exaustão operando pelo menos uma válvula de exaustão em resposta a pelo menos uma came de exaustão para produzir pelo menos de evento de exaustão principal, um evento de retardamento de motor e um evento de recirculação de gás de exaustão. A montagem de atuação de válvula de exaustão é capaz de operar em dois modos, a pelo menos uma válvula é operada para produzir pelo menos um do evento de exaustão principal, o evento de retardamento de motor e o evento de recirculação de gás de exaustão."VALVE ACTING SYSTEM FOR AN INTERNAL COMBUSTION ENGINE". The present invention is directed to a valve actuation system for an internal combustion engine. The valve actuation system additionally includes an intake valve actuation assembly to operate at least one intake valve in response to an intake cam. The valve actuation system additionally includes an exhaust valve actuation assembly operating at least one exhaust valve in response to at least one exhaust cam to produce at least one main exhaust event, one engine delay event and one exhaust gas recirculation event. The exhaust valve actuation assembly is capable of operating in two modes, at least one valve is operated to produce at least one of the main exhaust event, the engine delay event and the exhaust gas recirculation event.
