Abstract

PROCESSO PARA OPERAÇçO DE UM MOTOR DE COMBUSTçO INTERNA. A presente invenção refere-se a operação de um motor de combustão interna, um enchimento de ar (ri) em uma câmara de combustão que é determinada sob consideração de uma pressão (ps) em um canal de aspiração. Propõe-se que o ar de enchimento (ri) seja determinado com base em um modelo (A), que obtém como grandezas de entrada um número de rotações (nmot) do eixo de manivela (44) e uma relação da pressão (ps) no canal de aspiração (22) para uma pressão ambiente (pu).
