Abstract

Patente de Invenção: <B>"PROCEDIMENTO PARA REGULAçãO DA RELAçãO AR-COMBUSTìVEL EM UM MOTOR DE COMBUSTãO INTERNA''<D>. A invenção refere-se a um procedimento para regulação da relação ar-combustível em um motor de combustão interna, em que o sinal de saída de uma primeira sonda Lambda, que está disposta no canal dos gases de escape de um motor de combustão interna antes de um catalisador, é fornecido a um regulador e o regulador fornece uma variável de regulação para a relação ar-combustível e em que o regulador recebe um sinal de correção, que é obtido do sinal de saída de uma segunda sonda Lambda disposta atrás do catalisador. De forma a se possibilitar uma regulação precisa e adequada, que melhore ainda mais a relação ar-combustível no que se refere a uma redução das emissões dos gases de escape, o sinal de correção é ponderado dependendo da duração de período da primeira sonda Lambda.
