What Causes Loud Engine Acceleration Noise?
3 Answers
Engine acceleration noise can be caused by: 1. Overheating engine coolant; 2. Issues with the exhaust system; 3. Excessive oil viscosity causing engine operation problems; 4. Loose belts increasing noise in the engine compartment; 5. High vehicle idle speed. Solutions for loud engine acceleration noise: 1. Perform engine maintenance; 2. Regularly schedule car maintenance and oil changes; 3. Visit a professional repair shop for throttle body cleaning. Engine types include: 1. Piston engines; 2. Ramjet engines; 3. Rocket engines; 4. Turbine engines.
My old car used to make a particularly loud noise when accelerating, as if the exhaust pipe had a leak, making it sound like a tractor roaring. It could also be that the timing belt was loose, or the intake system was clogged, like a dirty air filter not letting enough air in, causing the engine to struggle and sound noisy. Also, if the engine oil was insufficient or of poor quality, the increased friction inside the engine made it roar even louder. Once, while driving on the highway, the noise suddenly got louder, scaring me into pulling over immediately. The mechanic found that the exhaust connection was broken, and after fixing it, the car became much quieter. I recommend regularly checking the engine oil and belts—this not only extends the car's lifespan but also saves some fuel costs. Keeping up with regular maintenance is key.
When I was driving my small car, the acceleration noise suddenly became louder, giving me a headache. A friend mentioned his car had the same issue before, possibly due to insufficient air intake, like a clogged air filter or excessive carbon buildup making the engine struggle. We went to the repair shop, and after they cleaned the intake system, the problem significantly improved. Also, worn-out spark plugs or incorrect valve timing causing misfires can amplify the noise. After using a high-quality fuel cleaner for a while, I noticed some improvement. Everyone should pay attention to changes in their car's sound—early detection and action can save money, so don't wait until the car completely breaks down to panic.
