What Causes the Engine to Make a Whistling Sound When Accelerating?

[Anna]

The reasons for the engine making a whistling sound when accelerating are: 1. Loose connection between the intake grille and the air filter pipe; 2. Whistling from the external belt and mechanical parts inside the engine. The accelerator is located below the main driver's console, also known as the throttle or air valve, and refers to the control device that regulates engine power. It is operated by the driver via the throttle lever in the cockpit, which transmits commands through the control system to the carburetor or fuel regulator on the engine. An engine is a machine capable of converting one form of energy into another, typically transforming chemical energy into mechanical energy, and includes internal combustion engines and external combustion engines.
