What are the reasons for the squeaking sound when stepping on the accelerator in the new Sylphy?

[DeBeckett]

Introduction to the reasons for the squeaking sound when stepping on the accelerator in the new Sylphy: Engine temperature is too low: When the car is cold-started, the engine temperature is relatively low, and various parts and oils have not reached an optimal working environment and state; Lack of engine oil: This can cause the engine oil to deteriorate, affecting lubrication and resulting in abnormal noises from part friction; Damaged half-shaft: Including twisted or broken half-shafts, and worn spline teeth; Loose engine belt: Leading to idling when accelerating. 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 opening to regulate the cylinder's filling volume, determining the engine's output power. In gas turbine engines, the throttle controls the metered fuel flow of the fuel regulator, determining the thrust generated by the engine.
