Patent number: 10514014Abstract: A system and method for enhancing spark generation in an ignition coil of an internal combustion engine at low rotational speeds of the flywheel. The method and system monitor the rotational speed of the flywheel and, when the rotational speed of the flywheel is below a threshold rotational speed, the system and method supplies voltage pulses to the primary winding. The timing of the voltage pulses supplied to the primary winding are triggered off of voltage transitions in pulses induced in the primary winding upon rotation of the flywheel. Once the internal combustion engine has started, the switching device transitions into a second condition to disconnect the electrical storage device from the primary winding. The spark generation system of the present disclosure allows for starting of an internal combustion engine upon slower initial rotational speeds.Type: GrantFiled: July 3, 2018Date of Patent: December 24, 2019Assignee: Briggs & Stratton CorporationInventors: Robert John Koenen, Jason A.

Patent number: 4645939Abstract: An automotive device for inhibiting engine ignition in response to operation of an ignition switch in a manner inconsistent with a prescribed routine which varies unpredictably. The device has two operational modes for impairment detection and theft deterrence, the respective modes being enabled by a plurality of switches. A gauge warning light is energized in response to the ignition switch being turned to a first active position. After a variable interval of time the gauge warning light dims. Following the initiation of dimming, the operator must turn the ignition switch to a second active position within a "window of time", whereby the operator's reflexes and concentration are tested. Failure of the operator to turn the ignition switch within the "window of time" results in disablement of the starter.Type: GrantFiled: August 8, 1985Date of Patent: February 24, 1987Inventor: Ronald J.
