  • Publication number: 20190136808
    Abstract: A fuel delivery injector includes a housing, an end cap including an inlet port fluidly coupled to a cavity to direct fuel vapor and liquid fuel into the cavity and an outlet port fluidly coupled to the cavity to direct fuel vapor and liquid fuel out of the cavity, a magnetic assembly fixedly positioned within the cavity, and a pumping assembly including a bobbin and a piston. A return spring is coupled to the pumping assembly to bias the pumping assembly to a home position and a valve assembly including a biasing spring is positioned between an inlet chamber and an outlet chamber. The liquid fuel entering the housing through the inlet port flows from the inlet port to the cavity and fuel vapor entering the housing through the inlet port is directed through a conduit to the outlet port.

  • Publication number: 20190101092
    Abstract: An internal combustion engine includes an engine block, an electric motor, a worm coupled to and rotated by the electric motor, a worm gear coupled to and configured to be rotated by the worm, a crankshaft configured to rotate about a crankshaft axis, a flywheel including a flywheel cup having flywheel protrusions, a clutch driven by the worm gear and configured to engage the one or more flywheel protrusions such that the crankshaft is rotated, and an energy storage device electrically coupled to the electric motor. The clutch is configured to disengage from the flywheel protrusions when the rotational speed of the crankshaft exceeds the rotational speed of the worm gear. When the electric motor is activated, the electric motor rotates the worm rotating the worm gear, which causes the clutch to engage the flywheel protrusions, transferring worm gear rotation to the flywheel and the crankshaft to rotate the engine for starting.
