Internal combustion engine fuel injection valve controller having inductor element applying electromagnetic charge with switch switching capacitive state/voltage reference applying charge/stopping charge

摘要

The electromagnetic charge applying mechanism (M) has a charge (Ai) with an inductor element (Li). There is a source (B) of low voltage continuous current and a comparator element (C). A switch (Swb,Swc) switches between a capacitive state and a voltage reference. A control mechanism (X) selects a first state whilst applying a charge and a second state when it is stopped.
