  • Patent number: 11619198
    Abstract: An engine apparatus includes a fuel supply system which may comprise a fuel reservoir, primary fuel supply path extending from a fuel inlet in fluid cooperation with the fuel reservoir to a fuel outlet, pressure pulse source, and first and second pressure-operated fuel pumps located along the primary fuel supply path; each of fuel pumps operably coupled to the pressure pulse source. The fuel pumps may be pulse type pumps arranged in series from a flow standpoint along the primary fuel supply path such that fuel discharged by the first fuel pump is supplied to the second fuel pump. The fuel pumps may be mounted and to the engine or appurtenance thereof in a stacked or side-by-side relationship. The pressure pulse source may be the engine crankcase in some designs. The flow and pressures delivered by the series flow fuel pumps are suitable for use with four stroke/cycle engines.

  • Patent number: 7270111
    Abstract: A common engine speed control mechanism for small internal combustion engines, which may be configured to allow for actuation of the speed control mechanism between stop, idle, and various engine running speed positions by actuation of one of a selected plurality of speed control levers. Each of the plurality of speed control levers is oriented so that it is movable in a direction which is substantially non-parallel to the direction of movement of the other speed control levers. In one embodiment, the actuation of the common speed control mechanism can be accomplished by movement of a first speed control lever in a substantially horizontal, side-to-side direction or by movement of a second speed control lever in a substantially vertical, up-and-down direction.
