Abstract

Patente de Invenção: <B>"DISPOSITIVO DE ESTIMATIVA DE RIQUEZA DE SISTEMA DE INJEçãO PARA MOTOR à COMBUSTãO INTERNA"<D>. O dispositivo de estimativa da riqueza da mistura admitido em cada uma das n câmaras de combustão de um motor que tem injetores compreende um sensor (26) que fornece um sinal de saída com variação sensivelmente linear com a riqueza, instalado em um ponto de confluência dos escapamentos das câmaras e meios de cálculo. Esses meios memorizam um modelo de comportamento do escapamento no ponto de confluência baseado na hipótese de a riqueza no ponto de confluência ser uma soma ponderada das contribuições dos escapamentos das câmaras individuais, o coeficiente de ponderação sendo tanto menor quanto mais antiga for a combustão na câmara e estimam, após cada passagem no ponto morto alto, a relação ar/combustível a partir dos valores medidos e do modelo. O modelo de comportamento um submodelo particular por câmara de combustão tendo, para a câmara de ordem i, um filtro de Kalman com uma matriz de coeficientes C~ ij~ e uma matriz de ganhos K~ ij~ própria, i correspondendo a número de câmara e j correspondendo ao número de coeficiente de ponderação.
