INDIVIDUAL CORRECTING SYSTEM FOR THE ELECTRONICALLY CONTROLLED ELECTROMAGNETIC INJECTORS IN INTERNAL COMBUSTION ENGINES

摘要

The invention provides an individual correction of the duration of the injection of fuel into any one of the injectors of an internal combustion engine. To this end the signals generated by electronic control means and fed into the solenoid controlling injectors are diverted into a circuit connected across the terminals of the solenoid and including in series an adjustable impedance such as a resistance which may be in parallel with an adjustable capacitance and at least one diode the direction of which defines whether the lag is obtained for the opening or for the closing of the injector. A preferred embodiment of said circuit includes a resistance connected with the slider of a potentiometer the ends of which are connected with diodes connected in opposite directions and in parallel in the circuit so that according to the position of the slider the lag-producing action is predominantly that of one or the other diode.
