Why is there a sound when stepping on the accelerator pedal?

[CharlesDella]

There are several reasons for the sound when stepping on the accelerator pedal: For new cars, there are two possible situations. You can check the instrument panel and then inspect the transmission. If there is oil contamination, it may cause noise from the transmission oil pump. You can also check if there is gasoline detonation. The main focus is to examine whether the instrument panel and dashboard are loose, and it's also possible that the new car is undergoing a break-in period. The accelerator pedal, also known as the throttle or gas pedal, is a control device that regulates engine power. In piston aircraft engines, the throttle controls the carburetor's throttle opening to regulate the cylinder's filling volume, thereby determining the engine's output power. In gas turbine engines, the throttle controls the metered fuel flow of the fuel regulator, thus determining the thrust generated by the engine.
