Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO DE AUTO-ADAPTAçãO RáPIDA DA RIQUEZA DA MISTURA PARA MOTOR DE COMBUSTãO INTERNA"<D>. O processo de auto-adaptação da riqueza da mistura de um motor de injeção (1) através de um computador (21) ligado a captores (26, 28) que fornecem um parâmetro de enchimento do motor e a uma sonda de oxigênio (33) nos gases de escape consiste, a cada ciclo de adaptação, em definir uma nova reta de uma grandeza de comando em função do parâmetro de enchimento com o auxílio de novos coeficientes calculados a partir das coordenadas de 2 pontos aos quais correspodem valores corrigidos da grandeza de comando a partir de uma reta de trabalho filtrada e memorizada no ciclo precedente, pelo menos um dos 2 pontos sendo anteriormente adquirido, e depois em adotar como nova reta de trabalho, uma reta intermediária entre a nova reta e a reta de trabalho anterior. Aplicação para o comando dos motores de injeção.
