Abstract
To prevent bucking of a fuel injection operated automotive engine, under transient dynamic conditions, due to resilient suspension thereof, a timing capacitor in the fuel injection system has an auxiliary capacitor connected in parallel thereto over a diode, the auxiliary capacitor having its own charge circuit, and the diode and charge circuit being so arranged that the diode becomes conductive when the voltage across the main capacitor exceeds the voltage across the auxiliary capacitor, thus delaying and flattening the charge rate to the main capacitor without, however, detracting from total charge being placed on both capacitors to prevent excessive changes in fuel valve injection timing under transient engine operating conditions.
