Driving apparatus for starting an engine with starter motor energized by a capacitor
First Claim
1. A driving apparatus supplying electric power from a battery to a starter motor coupled to a crankshaft of an engine mounted on a motor vehicle for driving the starter motor, and starting the engine with the starter motor, said driving apparatus comprising:
- a battery;
a starter for starting an engine with electric power from said battery;
a large-capacity capacitor interconnecting said battery and said starter;
switching-over means for selectively connecting said capacitor in parallel or in series to said battery; and
control means for controlling said switching-over means to normally connect said capacitor in parallel to said battery and to connect said capacitor in series to said battery when starting the engine with said starter.

Abstract
An engine starter system includes a switching-over circuit arrangement for selectively connecting a large-capacity capacitor parallel or in series to a battery. Normally, the capacitor is connected parallel to the battery and charged thereby. When starting an engine with a starter, the charged capacitor is connected in series to the battery, and the voltage of the capacitor and the voltage of the battery are added and applied to the starter to energize a starter motor for starting the engine.
