What Causes the Engine to Make Loud Noises When Accelerating?
2 Answers
Reasons for loud engine noises when pressing the accelerator include: 1. Engine overheating causing loss of power. 2. Blocked internal engine valves. 3. Exhaust pipe leakage. 4. Dirty or clogged throttle. 5. Engine misfire (cylinder failure). 6. Low power steering fluid. 7. Damaged generator bearings. 8. Issues with power steering pump or water pump. Below is relevant information about the accelerator: The accelerator, also known as the throttle, controls engine power output. The driver operates the throttle lever in the cockpit, which transmits commands through the control system to the carburetor or fuel regulator on the engine.
I recently noticed that when I step on the gas pedal, the noise becomes extremely loud, like thunder, which is quite annoying. This is usually due to an exhaust system leak, such as a broken muffler or cracked exhaust pipe, where escaping air creates noise; it could also be caused by a loose engine belt producing a squealing sound. If you experience a sudden increase in noise while driving, especially during acceleration, it's best to pull over immediately and check to avoid more serious issues that could affect safety. I went through this once myself—when I took it to the repair shop, they found the muffler was damaged. After spending a bit to replace it, the car became much quieter. Regular maintenance should include checking the exhaust system and belts to prevent such problems. Increased noise during high-speed driving can also be distracting, so don’t overlook this small detail.
