Abstract

dispositivo de controle para motor de combustão interna. trata-se de um dispositivo de egr que serve para recircular um gás de escape retornando-se uma parte do gás de escape que flui em uma passagem de escape até uma passagem de admissão que é fixado a um motor de combustão interna. uma unidade de controle eletrônico executa um processo para especificar e armazenar uma região de cetano à qual um número de cetano do combustível a ser fornecido ao motor de interna pertence. durante um período de execução imediatamente após a iniciação da do motor de combustão interna e em uma situação específica onde uma região de número cetano baixo é armazenado (t11 a t12), a unidade de controle eletrônico ajusta uma abertura de egr (csr) em uma operação ociosa para 0 e ajusta uma temporização de injeção necessária (tst) na operação ociosa em uma temporização retardada comparada a uma situação não-específica.
