Abstract

Patente de Invenção:<B>"PROCESSO PARA A DETECçãO DE FALHAS DE IGNIçãO"<D>. Propõe-se um processo para a detecçao de falhas de ignição em motores de combustão interna, no qual processo é formada uma medida para a instabilidade da marcha do motor de combustão interna, e é comparada com um valor limite, o qual depende da carga do motor de combustão interna, e onde uma ultrapassagem do valor limite é interpretada como falha de ignição. O processo destaca-se pelo fato, - que o valor limite é dependente, adicionalmente à dependência da carga, também do ângulo de defasagem da ignição e/ou do valor Lambda - ou que a formação da medida para a instabilidade da marcha efetua-se também em dependência do ângulo de defasagem da ignição e/ou do valor Lambda - e/ou que a ativação/desativação da detecção de falhas de ignição depende pelo menos do ângulo de defasagem da ignição e/ou do valor Lambda.
