Abstract

"MéTODO E DISPOSITIVO PARA O ACIONAMENTO DE UM INJETOR EM UM MOTOR DE COMBUSTãO INTERNA". Referente a um método para o controle de um injetor (2) em um motor (3) de combustão interna, no qual, para um ciclo específico do motor, uma unidade de controle 13 calcula um valor desejado (Tinj) de tempo de abertura do injetor (2) e envia este valor desejado (Tinj) a um circuito de acionamento (12) do injetor (2), um dispositivo de supervisão (11) calcula um valor real (Tinjeff) do tempo de abertura do injetor (2) durante a fase de injeção, compara este valor real (Tinjeff) com o valor desejado (Tinj) e gera um sinal de erro caso a diferença entre o valor desejado (Tinj) e o valor real (Tinjeff) esteja fora de uma predeterminada faixa de aceitação.
