Patent number: 11927164Abstract: A throttle body assembly for a combustion engine includes a throttle body having a pressure chamber including a supply of liquid fuel, and a throttle bore with an inlet through which air is received. A throttle valve is carried by the throttle body with a valve head movable relative to the throttle bore. A metering valve is coupled to the throttle body, and has a valve element that is movable between open and closed positions. A boost venturi is located in the throttle bore and has an inner passage that is open at both ends to the throttle bore. The boost venturi has an opening through which fuel flows into the inner passage when the valve element is in the open position, wherein fuel flows from the pressure chamber to the metering valve under the force of gravity or under a pressure of less than 6 psi.Type: GrantFiled: November 17, 2022Date of Patent: March 12, 2024Assignee: Walbro LLCInventors: Gary J. Burns, Andreas D. M. Dixon, Eric G. Zbytowski, Albert L Sayers, Justin T. Dolane, David L Speirs, William E. Galka, Duried F. Rabban, Bradley J. Roche

Patent number: 11644002Abstract: An assembly for an engine includes a control module including a controller operable to control at least certain aspects of the operation of the engine, a display including an input connected to the controller, and a wireless receiver connected to the controller. The wireless receiver is arranged to receive a signal from a wireless device to cause the controller to send an engine start signal to cause starting of the engine and wherein the input when actuated causes the controller to send an engine start signal to cause starting of the engine. In at least some implementations, no keyed ignition switch is provided to start the engine and the engine is started only via the wireless device or the input.Type: GrantFiled: March 22, 2022Date of Patent: May 9, 2023Assignee: WALBRO LLCInventors: Andreas D. Dixon, Justin T. Dolane, Sean M. Murphy, Duried F. Rabban, Bradley J. Roche, Elizabeth M. VanSipe
