Salut prieteni
Am nevoie de un montaj electronic,(schema ,documentatie) de comanda a 4 injectoare de Logan benzina
In esenta nu e ceva complicat, un multivirator cu 555 cu frecventa si factor de umplere reglabile, iar injectoarele sa fie comandate secvential ( un 4017 sau ceva similar) printr-un Fet sau BU de putere.
vreau sa fac un stand de curatare injectoare cu ultrasunete.

Practic e un oscilator de 0-400Hz, cu factor de umplere variabil, urmat de un divizor cu 4 , si de 4 iesiri de putere, toate cu alimentare 12V
