Abstract

"MODIFICAçãO COM BASE NA VELOCIDADE DO MOTOR DA RECIRCULAçãO DE GáS DE EXAUSTãO DURANTE FENÈMENOS TRANSITóRIOS DE ABASTECIMENTO". A presente invenção refere-se aos dados da velocidade do motor N e os dados do abastecimento de combustível do motor MFDES que são processados por uma estratégia (22) que multiplica (28) os dados do fenómeno transitório de abastecimento de combustível MFDES TRANSIENT e os dados do modificador com base na velocidade EGR_N_TRANS_MULT para desenvolver os dados do fenómeno transitório de abastecimento de combustível com base na velocidade. Os dados do fenómeno transitório de abastecimento de combustível com base na velocidade são então processados de acordo com uma função (32) que correlaciona os valores de um modificador de fenómeno transitório de abastecimento de combustível com os valores dos dados do fenómeno transitório de abastecimento de combustível com base na velocidade para desenvolver os dados do modificador de recirculação de gás de exaustão. Os dados da modificação de recirculação de gás de exaustão e os dados da recirculação de gás de exaustão básica são multiplicados (34) para desenvolverem os dados da recirculação de gás de exaustão modificada, e o gás de exaustão é recirculado de acordo com os dados da recirculação de gás de exaustão modificada. O uso da velocidade do motor como um determinante da extensão com relação à qual a taxa EGR básica deve ser modificada durante um fenómeno transitório de abastecimento de combustível permite um melhor controle sobre certas emissões de exaustão sobre certas faixas de velocidade.
