Abstract: A controller may use energy packets to control a prime mover of a machine. The controller may include an energy packet measurement control to calculate energy packets and convert the energy packets into a fuel valve reference. Further, a frequency control may receive system feedback associated with the monitored machine and generate a frequency correction based on the system feedback. The controller may add the energy packet value and the frequency correction to determine a prime mover power reference and provide the prime mover power reference to a fuel valve control of the machine.

Abstract: In at least some implementations, a charge forming device includes a main body, a throttle valve and an adjuster. The main body includes a main bore through which fluid flows for delivery to an engine. The throttle valve is carried by the main body and moveable relative to the main bore to control fluid flow through the main bore. And the adjuster is moveable relative to the throttle valve and engageable with the throttle valve to adjust the range of motion of the throttle valve. In at least some implementations, the adjuster limits the range of motion of the throttle valve when the adjuster is engaged with the throttle valve.

Abstract: A control device for an engine, which controls an engine torque based on operation of an organ-type accelerator pedal is provided. The control device includes an accelerator opening detector for detecting an accelerator opening based on an angle of an accelerator pedal, a target acceleration setter for setting a target acceleration based on the accelerator opening, and an engine controller for adjusting an engine torque to achieve the target acceleration. The accelerator pedal is arranged to have a pedal angle at a predetermined initial pedal angle when the accelerator pedal is not pressed. The target acceleration setter sets the target acceleration to zero when the accelerator pedal is pressed and the accelerator opening is within a range where a difference between the pressed pedal angle and the initial pedal angle is between 2 and 4 degrees.

Abstract: A combination lever for a carburetor is an integrated shutoff lever and fuel valve. The combination lever includes a longitudinal portion for a handle and a cylindrical portion including a fuel path for the fuel valve. A carburetor casing is shaped to form a valve chamber and a carburetor chamber. The valve chamber supports the cylindrical portion. A directional cavity formed in the cylindrical portion of the combination lever regulates a flow of fuel to the carburetor chamber according to a rotation of the combination lever. At one position the directional cavity opens the fuel path so that fuel flows into the carburetor chamber. At another position the directional cavity closes the fuel path so that the flow of fuel is blocked. The combination lever may also include an abutment portion to engage a switch for completing an electrical shutoff path to an engine coupled to the carburetor.
