Why is the engine noise loud when accelerating from a standstill?

[DeElle]

The reasons for loud engine noise when accelerating from a standstill are as follows: The loud noise when pressing the accelerator pedal may be caused by engine malfunctions or issues with the car's engine oil, such as excessive oil or inappropriate oil viscosity. Additional information: 1. The sound produced when pressing the accelerator is related to the engine's RPM. The greater the throttle, the higher the engine's RPM, resulting in louder noise, which is normal under these conditions. 2. If there is too much engine oil, the engine crankshaft will encounter greater resistance during rotation. This condition reduces engine power and alters the air-fuel ratio in the combustion chamber, increasing the likelihood of engine knocking during operation.
