Abstract

"MéTODO DE CONTROLE DE INJETOR COM VERIFICAçãO DE QUE OCORREU O MOVIMENTO DO êMBOLO". Em que o método proporciona a aplicação de voltagem variável ao longo do tempo (Vinj) aos terminais (5) e (6) de um circuito de direção (4) do injetor (2), a fim de fazer com que uma onda de corrente (linj) flua através do mencionado circuito de direção (4); detecção de voltagem de verificação (Vv) entre os terminais (5) e (6) do circuito de direção (4) após a corrente (linj) através do circuito de direção (4) haver apagado ao final da fase de injeção, medição de tempo de verificação (Tv) durante a qual a voltagem de verificação (Vv) é maior que primeiro valor limite previamente determinado (SVv) e diagnóstico da ausência de movimento do êmbolo caso o tempo de verificação (Tv) seja menor que segundo valor limite previamente determinado (STv).
