Patent number: 10393086Abstract: 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 rope pull starting or upon discharge of a starter battery.Type: GrantFiled: March 27, 2018Date of Patent: August 27, 2019Assignee: Briggs & Stratton CorporationInventors: Robert John Koenen, Jason A.
