METHOD AND DEVICE FOR INCREASING SPARK ENERGY IN CAPACITIVE-DISCHARGE IGNITION SYSTEMS Russian patent published in 2011 - IPC F02P3/09 F02P1/08 

Abstract RU 2418977 C2

FIELD: engines and pumps.

SUBSTANCE: invention refers to method and device for spark energy increase, namely in small "capacitive-discharge ignition systems" without storage batteries intended for internal combustion engines in which striking voltage is created by means of generator and its control circuit, which are connected to handwheel or built into it. Spark energy increasing device includes at least one charging winding (L1), the first rectifier (D1), charging capacitor (C1), primary (L3) and secondary (L4) windings of voltage transformer, the second rectifier (D2) and switching element (Q2). Charging winding (L1) charges capacitor (C1) through the first rectifier (D1). Capacitor (C1) is connected to primary winding (L3). At low speed of engine the switching element (Q2) from time to time short-circuits charging winding (L1) in order to increase the charge of capacitor (C1). Device can contain control unit (M1). Unit (M1) controls switching element (Q2) so that level of charging voltage on charging capacitor (C1) is maintained relatively constant in the whole range of engine speed. Switching element (Q2) can be made so that short circuit can be created for the purpose of engine stop.

EFFECT: maintaining sufficient charge level of capacitor at lower rpm speed.
