An automatic aircraft powerplant control system includes a throttle servo for adjusting a throttle valve via a throttle control linkage. A throttle control lever provides a user input to the throttle servo, and a throttle controller controls the throttle servo for controlling a throttle valve. A dual-redundant propellor servo drive provides propellor control, and a dual-redundant mixture servo drive controls an air-fuel mixture. A first processor and a second processor are communicatively coupled with the dual-redundant propellor servo drive and the dual-redundant mixture servo drive and with each other to provide dual-redundant propellor and mixture control. The throttle control lever provides a single lever for pilot control of aircraft power, and the throttle control configuration is compatible with an auto-land capability.

A throttle control lever provides a user input to the throttle servo, and a throttle controller controls the throttle servo for controlling a throttle valve. A propeller servo may be provided for adjusting a propeller governor setting of an engine. A propeller control lever provides a user input to the propeller servo, and a propeller controller controls the propeller servo. A full-authority digital engine control (FADEC) controller is used to automatically control mixing of fuel and air via a fuel-air mixture device. The FADEC controller may be used to automatically provide propeller control.

An engine operating device of a working machine includes a control assembly installed in a body, an operating lever mounted on a handle, and an operating cable. The control assembly includes a base member, a stop switch secured to the base member, and a lever member supported by the base member. The operating cable includes a throttle wire, a stop wire, and a cable tube in which the throttle wire and the stop wire are fitted. As the operating lever is moved to an engine stop position, the lever member moves to a release position, causing an engine to stop.

A fluid supply system for a machine such as an internal combustion engine includes a shutoff valve having an electrical actuator that includes a solenoid subassembly, and a stabilizer for the electrical valve actuator. The stabilizer includes a fitting structured to couple the shutoff valve to adjacent hardware in the fluid supply system, and a strongarm extending between the fitting and the solenoid assembly and clamped to the solenoid subassembly. A vibration-damping reinforced grommet may be clamped between the solenoid subassembly and the clamp.

The work vehicle includes: an operation tool through which opening and closing of a throttle valve is operated in accordance with a swing angle of the operation tool; a cable connected to the throttle valve; a cam which is supported by the operation tool and swingable about a first shaft supported by the vehicle body in accordance with an operation amount of the operation tool; a curved face which is an outer face of the cam and includes an end part region and a remaining region, the end part region having a curvature smaller than a curvature of the remaining region; and a link member which is connected to the cable, brought into contact with the curved face of the cam, and swingable along the curved face about a second shaft supported by the vehicle body in accordance with sing of the cam.
