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.
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 ...
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 ...
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 ...
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.
In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor.
Early cars had a hand lever to control the throttle, either directly, or by controlling an engine speed governor which in turn controlled both the throttle and timing. [6] In 1900 the Wilson-Pilcher car was introduced in Britain which had a hand controlled speed governor, and a foot throttle which could override the action of the governor.
Block diagram of the EOT signal system. At least two telegraph units and alarms must be installed, one on the bridge and one in the engine room. The order is given by moving the bridge unit's handle to the desired position on the dial face.
