Abstract
"MéTODO E APARELHO PARA DETERMINAR UMA POSIçãO DO OPERADOR DE VáLVULA". A presente invenção refere-se a uma posição do operador de válvula que é determinada para uma válvula de recirculação de gás de descarga (117) para um motor de combustão interna (101). A posição da válvula pode ser ajustada (313) para condições de velocidade do motor transientes e/ou ajustada (309) para condições de carga do motor transientes. Durante os estados de altos transientes, a válvula EGR é mais fechada, para permitir que mais ar alcance os cilindros do motor, por meio disto aperfeiçoando o desempenho do motor.
