ABSTRACT:
A motor vehicle high voltage ignition energy and duration augmentation comprising a primary recharging circuit, a diode capacitor circuit, a rear recharging circuit and a noise suppression circuit, wherein high voltage from an ignition coil is transmitted through said primary recharging circuit, said diode capacitor circuit, said rear recharging circuit and said noise suppression circuit to discharge through a spark plug for primary ignition, and at the same time, part of said high voltage is transmitted to charge the capacitor of said primary recharging circuit, the capacitor of said diode capacitor circuit and the capacior of said rear recharging circuit, causing the discharging resistor of said primary recharging circuit and the discharging resistor of said rear recharging circuit to instantaneously discharge high voltage for secondary ignition and, reverse voltage from said spark plug is sent to charge the capacitor of said rear recharging circuit and to drive the diodes of said diode capacitor to compensate the current.
