Abstract

técnicas para descongelar um injetor de redutor e um tanque de redutor antes de uma tentativa de injeção. a presente invenção refere-se a um método que inclui determinar, em um controlador (140) que tem um ou mais processadores, se uma temperatura ambiente (tamb) é menor que uma temperatura predeterminada (tth) indicativa do redutor congelado em um sistema de escape (100) de um motor (104). o método inclui determinar um período de descongelamento de injetor para um injetor de redutor (224) no sistema de escape quando a temperatura ambiente for menor que a temperatura predeterminada. o método inclui determinar um período de descongelamento de tanque para um tanque de redutor (216) associado ao sistema de escape, sendo que o tanque de redutor é configurado para fornecer o redutor para o injetor de redutor. o método também inclui controlar (i) um aquecedor (218) para aquecer o tanque de redutor pelo período de descongelamento de tanque e (ii) uma corrente fornecida para o injetor de redutor pelo período de descongelamento de injetor, de modo que o período de descongelamento de tanque e o período de descongelamento de injetor ter-minem ao mesmo tempo.
