Abstract
"MéTODO PARA CONTROLAR UM INJETOR DE COMBUSTìVEL". O presente invento descreve um método para controlar um injetor de combustível (1) provido de um acionador eletromagnético (5) operado eletricamente de modo a abrir o injetor (1) por um tempo de injeção (Tj) determinado; o método provendo que o injetor (1) seja operado com uma primeira forma de onda de corrente (A) se o tempo de injeção (Tj) for maior que um valor limiar (Ts) predeterminado, e que o injetor (1) seja operado com uma segunda forma de onda de corrente (B) se o tempo de injeção (Tj) for menor que o valor limiar (Ts) predeterminado; ambas as formas de onda de corrente (A;B) tendo uma parte inicial idêntica, durante a qual a corrente (i(t)) que passa através do injetor (1) é elevada até que atinja um valor de pico (Ip) que é mantido pela comutação cíclica da voltagem (v(t)) aplicada ao injetor (1) entre dois valores diferentes (0, Vc).
