Abstract

a presente invenção se refere a um método para diagnosticar abastecimento de combustível não intencional a partir de um ou mais injetores de combustível de um motor de combustão interna de múltiplos cilindros durante a operação de motor. o combustível pressurizado se destina a ser distribuído por meio dos ditos injetores de combustível a partir do dito tanque acumulador para os cilindros, para combustão. um catalisador de oxidação é disposto a jusante dos ditos cilindros. o método compreende as etapas para: determinar (s1) a pressão no tanque acumulador de combustível e se a dita pressão está diminuindo; e determinar (82) se a quantidade real de combustível fornecida pela unidade de bomba excede a quantidade exigida de combustível. o método compreende adicionalmente as etapas para: determinar (83) se a temperatura associada ao catalisador de oxidação está acima de um nível determinado e/ou determinar (s4) se a razão entre ar/combustível está abaixo de um nível determinado e/ou determinar (85) se uma quantidade de matéria particulada está acima de um nível determinado; e confirmar (s6) um abastecimento de combustível não intencional com base nas condições determinadas.
