Abstract

"PROCESSO PARA CONTROLE DE DISTRIBUIçãO DE COMBUSTìVEL EM UM INJETOR DE COMBUSTìVEL, MEIO DE ARMAZENAMENTO DE LEITURA POR COMPUTADOR, E, MOTOR A DIESEL" Um processo para controle de distribuição de combustível em um sistema de injeção de combustível capaz de realizar uma injeção separada inclui a comparação de, pelo menos, uma temperatura de operação do motor com um limite de temperatura e desabilitação da injeção separada quando, pelo menos, uma temperatura de operação do motor exceder o limite de temperatura. A desabilitação da injeção separada desta maneira melhora a operação do motor a baixa temperatura, proporcionando ainda uma injeção simples a temperaturas mais elevadas, caso se queira. Ainda, são também dispostos um motor (12) e um meio de armazenamento legível por computador (28), possuindo informação armazenada no mesmo representado instruções executáveis através de um controlador do motor (22) para comparar, pelo menos, uma temperatura de operação do motor com um limite de temperatura. O meio de armazenamento legível por computador descapacita a injeção separada, quando, pelo menos, uma temperatura de operação do motor excede o limite de temperatura.
