Abstract:
A device for controlling an electromagnet (7) controlling a metering valve of a fuel injector (6) of an internal combustion engine (5), and which comprises an electric circuit (11) for generating a first electric current (13) of such a predetermined value as to excite said electromagnet (7) to open said metering valve; said electric circuit (11) generating a second electric current (14) of a value lower than said predetermined value and such as to keep said electromagnet (7) so excited; timing means (12) being provided to control said electric circuit (11) as a function of operating conditions of said engine; and the device being characterized in that said timing means also control said electric circuit (11) in such a manner as to vary the duration (t3-t1) of said first current (13) as a function of the operating temperature of said engine (5).
