  • Publication number: 20170226979
    Abstract: A self-contained starting module for outdoor power equipment that has control circuit and a start button. The starting module includes internal control circuit that can be either microprocessor based or analog. The control circuit receives a start signal from a start button of the starting module. The control circuit monitors for the presence of an enable device and, upon activation of the start button and the presence of the enable device, provides electric power to the electric load of the power equipment. When the start button is depressed for longer than a minimum engagement period, the control circuit initiates operation of the engine. If the start button is pressed for less than the minimum engagement period, the control circuit activates the electric load for an auxiliary period without starting the engine. During engine operation, if the start button is depressed, the operation of the engine is terminated.

  • Publication number: 20170138330
    Abstract: An ignition system for an internal combustion engine that utilizes a single primary coil and a single secondary coil to drive a pair of spark plugs. Current flowing in both a first direction and a second direction passes through the primary coil. The current flowing through the primary coil induces corresponding current in the secondary coil, which flows from the secondary coil to one of two spark plugs. Each spark plug is coupled to the secondary coil such that each of the two spark plugs receives current flowing only in a single direction. The current flowing through the ignition system can be from either a power source or created by the rotation of a flywheel having a series of magnet clusters.

  • Publication number: 20160233694
    Abstract: A battery pack for use to provide starting power of an internal combustion engine. The battery pack includes an outer housing that encloses a plurality of individual battery cells organized into two battery groups. A charging circuit is contained within the outer housing, which allows the battery cells to be recharged without the need for a charging device other than the battery pack. The charging circuit allows the battery cells to be recharged from either a wall outlet or from the alternator of the internal combustion engine. The battery pack further includes a switching circuit that can configure the battery groups in either a parallel mode or a series mode. In the series mode, the output voltage of the battery pack is increased for starting a cold engine. In the parallel mode, the amount of current available from the battery pack is increased.

  • Publication number: 20100114464
    Abstract: An engine control, communication and starting system for outdoor power equipment that has a controller and a one or more safety interlocks. The controller monitors the status of the safety interlocks to determine whether the internal combustion engine can be started upon activation of a starting device. If the starting device is activated and one or more of the safety interlocks is in a condition that prevents operation of the engine, the controller generates a feedback message to the operator through a feedback system. The feedback message can be either an audible or visual message that relays information to the operator. The system further includes a speed selection circuit that allows the operator to select the desired engine speed. The controller operates the internal combustion engine at the selected engine speed. During engine operation, the controller terminates operation of the engine if any of the safety interlocks move to an un-allowed status.
