[OSamantha]

The reasons for a buzzing sound when accelerating a car are: 1. Unstable engine operation; 2. Carburetor malfunction or delayed ignition timing; 3. Excessive engine carbon buildup or poor filtration; 4. Insufficient lubrication of engine components by the oil. The solutions for a buzzing sound when accelerating are: 1. Check if the engine is operating unstably; 2. Inspect the carburetor for faults or if the ignition timing is delayed; 3. Examine whether there is excessive carbon buildup in the engine or poor filtration; 4. Check the oil lubrication condition. The function of the throttle is: To control the cylinder's filling volume by adjusting the carburetor's throttle opening and to regulate the fuel flow through the fuel regulator, thereby determining the engine's output power and generating thrust.
