What causes the dry friction feeling in the accelerator pedal?

[DiAlana]

The dry friction feeling in the accelerator pedal is caused by a damaged engine mount. Simply replace it to resolve the issue. The accelerator, also known as the "throttle" or "air valve," refers to the control device that regulates the engine's power (thrust). In piston aircraft engines, the throttle controls the carburetor's throttle valve opening to regulate the cylinder's filling volume, thereby determining the engine's output power. In gas turbine engines, the throttle controls the metered fuel flow of the fuel regulator, thus determining the thrust generated by the engine. The throttle position is manipulated by the pilot in the cockpit via the throttle lever, which transmits the control through components such as pushrods, rockers, torque tubes, cables, pulleys, and sector gears to the carburetor or fuel regulator on the engine.
