What Causes the Abnormal Noise in the Xingrui Accelerator Pedal?
3 Answers
Xingrui accelerator pedal abnormal noise may be caused by carbon deposits on the throttle valve leading to sticking; wear of the accelerator pedal support pin; or improper installation of the accelerator cable. Below is additional information: Introduction to the accelerator: The accelerator, also known as the "throttle," refers to the control device that regulates the engine power (thrust). In piston-type aircraft engines, the accelerator controls the opening of the carburetor throttle valve to regulate the cylinder's air intake, 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 driver in the cockpit via the throttle lever, transmitted through control system components such as pushrods, rocker arms, torque tubes, cables, pulleys, and sector gears to the carburetor or fuel regulator on the engine. Precautions: Avoid using a large throttle when starting an unloaded vehicle; a small throttle is recommended. For starting under load, a medium throttle is advisable.
Last time my Xingrui's accelerator pedal also made noise for a while, and later I found it was mainly caused by these issues. The most common one is lack of lubrication in the joints around the pedal. After long-term use, it tends to squeak. Like my car, when stepping on the gas, there was a friction sound, but adding some engine oil made it much quieter. Another possibility is that the screws fixing the pedal are loose or worn out. The more you drive, the easier the screws become loose. Check the pedal mounting points under the rear seat and try tightening them. Also, if dust and debris get stuck in the pedal gaps while driving, it can cause strange noises. Like me, who often works at construction sites, the car interior gets dirty frequently, and cleaning it up solves the problem. Additionally, if it's an electronic throttle, there might be sensor issues or poor wiring contact, which requires professional tools at a repair shop for diagnosis. In short, all these issues are related to daily use. Don't wait until they become serious and affect safety. It's recommended to visit a professional shop for inspection and pay attention to regular maintenance of the pedal area.
I've been driving my Xingrui for many years, and recently the accelerator pedal has started to make a slight squeaking sound, which is quite annoying. From my experience, the noise might come from mechanical wear, such as rust at the pedal's joint or aging rubber pads—applying some grease after removing it can help a lot. Also, if the car has been jolted over bumpy roads, the screws might have loosened. I once noticed the sound getting louder while driving on the highway, so I stopped to check and tightened them, which fixed the issue. Environmental factors can also play a role, like high humidity during the rainy season causing parts to expand, or small debris like pebbles stuck on the pedal—clearing them usually solves the problem. I recommend trying simple fixes first before spending money on repairs. Although the noise seems minor, it can be distracting and potentially lead to accidents, so make it a habit to regularly check the pedal's tightness. I do a visual inspection every week, which has saved me a lot of trouble.
