Control Circuit For Capacitor Discharge Ignition System

View page
US Patent:
7069921, Jul 4, 2006
Filed:
Feb 9, 2005
Appl. No.:
11/054238
Inventors:
Lewis M. Kolak - Reese MI,
Assignee:
Walbro Engine Management, L.L.C. - Tucson AZ
International Classification:
F02P 1/00
US Classification:
123599, 123648
Abstract:
A capacitor discharge ignition (CDI) system for a light-duty spark ignition combustion engine includes an analog control circuit having a charging circuit, a trigger circuit and a shutdown circuit. In response to activation of a kill-switch, the shutdown circuit causes a switching device to discharge an ignition capacitor. Through the use of an RC circuit, the switching device continues to be biased such that it prolongs the discharge of the ignition capacitor, thereby preventing it from storing charge for the upcoming ignition pulse. This generally continues until the engine has come to a stop, at which time the engine can be immediately restarted without having to reset anything. The control circuit may also include engine speed limiting and ignition timing features.

US Patent:
6932064, Aug 23, 2005
Filed:
Apr 28, 2004
Appl. No.:
10/833354
Inventors:
Lewis M. Kolak - Reese MI,
Assignee:
Walbro Engine Management, L.L.C. - Tucson AZ
International Classification:
F02P003/06
US Classification:
123605, 123618, 123594
Abstract:
A capacitor discharge ignition (CDI) system includes a trigger circuit that generates a trigger signal in synchronism with operation of an engine for discharging an ignition capacitor. A timing circuit is connected to the trigger circuit for controlling the timing of the trigger signal and includes a timing coil for generating a timing signal in synchronism with operation of the engine. The timing circuit further includes a switch that has primary electrodes connected to the trigger circuit and a control electrode coupled to the timing coil for shorting the trigger circuit as a function of engine speed. The CDI system is thus capable of advancing engine timing to enable low-speed startup. The timing circuit is further adaptable to provide skip-spark speed-governing, timing retard speed-governing, and anti-reverse rotation of the engine.
