  • Patent number: 10130962
    Abstract: A pressure washer includes a prime mover, a pump driven by the prime mover, and a spray gun fluidly coupled to the pump. The spray gun includes a flow-control valve movable between an open position and a closed position to control a fluid flow from the spray gun, a user interface for controlling the flow-control valve, a sensor configured to detect the state of the user interface, and a first wireless system electrically coupled to the sensor. In a first state of the user interface, the flow-control valve is in the closed position. In a second state of the user interface, the flow-control valve is in the open position. The pressure washer further includes a second wireless system electrically coupled to the prime mover. The second wireless system signals the prime mover to start to drive the pump to provide fluid to the spray gun upon receiving a start signal from the first wireless system indicating that the sensor detects the user interface in the second state.

  • Publication number: 20180313318
    Abstract: 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.

  • Publication number: 20180298864
    Abstract: A starter motor that includes an integrated solid state switching device. The solid state switching device is mounted within the outer housing of the starter motor such that the entire starter motor can be installed as a single unit. In one embodiment, the solid state switching device includes a MOSFET positioned on the low side of the starter motor. The solid state switching device opens and closes to control the flow of current through the starter motor. In another embodiment, the solid state switching device is positioned on the high side of the starter motor. The solid state switching device can include a speed sensing circuit to prevent operation of the starter motor when the internal combustion engine is operation, a crank limiting circuit that limits the amount of time the starter motor can operate without starting the internal combustion engine and/or a thermal limiting circuit to prevent operation during overheating of the starter motor.
