What is the reason for the abnormal noise in the Xingrui accelerator pedal?

[SanEvan]

The abnormal noise in the Xingrui accelerator pedal may be caused by carbon deposits in the throttle valve leading to sticking; wear of the accelerator pedal support pin; or improper installation of the accelerator cable. Below is additional information: 1. Introduction to the accelerator: The accelerator, also known as the "throttle" or "air valve," is a control device that regulates the engine's power (thrust). In piston aircraft engines, the accelerator controls the opening of the carburetor's throttle valve to adjust the cylinder's filling volume, thereby determining the engine's output power. In gas turbine engines, the accelerator controls the metered fuel flow of the fuel regulator, thus determining the thrust generated by the engine. The accelerator position is manipulated by the pilot in the cockpit via the throttle lever, transmitted through control system components such as pushrods, rockers, torque tubes, cables, pulleys, and sector gears to the carburetor or fuel regulator on the engine. 2. Precautions: When starting an unloaded vehicle, avoid using a large throttle opening; a small throttle opening is recommended. For starting under load, a medium throttle opening is advisable.
