The stator blades moved from high to low position by an electrical solenoid and a stator valve, controlled by a switch on the throttle linkage. At light to medium throttle, the stator blades were at 32°, providing a torque multiplication of 1.8:1 and a converter stall speed of approximately 1800 rpm. At ⅔ to full throttle, the blades ...
This regulates internal pressure by throttle position. A secondary function of this cable is to down-shift ("kick down") to a lower gear when the Throttle Valve is in the full stop position (throttle pedal is fully depressed) and road speed is below a set point regulated by a mechanical governor on the output shaft.
A Bowden cable (/ ˈ b oʊ d ən / BOH-dən) [1] is a type of flexible cable used to transmit mechanical force or energy by the movement of an inner cable relative to a hollow outer cable housing. The housing is generally of composite construction, consisting of an inner lining, a longitudinally incompressible layer such as a helical winding or ...
Historically, the throttle pedal or lever acts via a direct mechanical linkage. The butterfly valve of the throttle is operated by means of an arm piece, loaded by a spring. This arm is usually directly linked to the accelerator cable, and operates in accordance with the driver, who hits it.
a throttle lever or regulator, which controls the amount of steam entering the cylinders [3]: 75 : 82 a reversing lever or (US term) Johnson bar, which controls the timing of the admission of steam into the locomotive's cylinders. [3]: 65 This is required for two purposes. One is to reverse the locomotive's direction, e.g. when shunting.
Accelerate-by-wire or throttle-by-wire, [17] more commonly known as electronic throttle control, is a system that actuates vehicle propulsion without any mechanical connections, such as cables, from the accelerator pedal to the throttle valve of the engine or other propulsion systems. In electric vehicles, this system controls the electric ...
Ignition switch - Activates the magnetos by opening the grounding or 'p-lead' circuit; with the p-lead ungrounded the magneto is free to send its high-voltage output to the spark plugs. In most aircraft the ignition switch also applies power to the starter motor during engine start. In piston aircraft engines, the battery does not generate the ...
Instead, the position of the throttle valve (i.e., the amount of air in the engine) is fully controlled by the ETC software via the electric motor. But just opening or closing the throttle valve by sending a new signal to the electric motor is an open loop condition and leads to inaccurate control.
