Abstract

<B>Método de Controle da Injeção e Ignição da Mistura Ar/Combustível em um Motor a Combustão Interna<D>. Método de controle compreendendo um método de controle da injeção e ignição da mistura de combustível e ar em um motor (2) de combustão interna, para acelerar o aquecimento de um conversor catalítico (6) disposto ao longo do duto de descarga (5) de gases de exaustão do motor (2), envolvendo os estágios de: fornecimento de uma mistura rica a um dado primeiro numero de cilindros do motor (2), por meio do que a razão de ar/combustível assume um valor menor do que a razão estequiométrica; fornecimento de uma mistura pobre aos cilindrios restantes do motor (2), por meio do que a razão de ar/combustível assume um valor maior do que a razão estequiométrica, e de uma tal maneira que a razão global de motor de ar/combustível do motor (2) fica assencialmente estequiométrica; e atrazando o momento de explosão efetiva (teff) da combustão em relação a um efeito nominal de explosão (t) em ao menos uma parte dos cilindros supridos de mistura rica, de uma maneira tal que uma combustão residual ao longo do duto de exaustão (5) e que acelera o aquecimento do conversor catalítico (6) - fg. 1 e 3.
