How to Solve the Problem of Loud Engine Acceleration Noise?
2 Answers
Engine noise is generally caused by carbon deposits. There are several specific reasons for increased engine noise: 1. Aging or loosening of engine mounts. Engine mounts are rubber blocks between the engine and the frame. Solution: Tighten or replace the engine mounts. 2. Improper use of engine oil. If the viscosity of the engine oil does not match the engine, it can easily lead to carbon deposits, resulting in increased engine noise. Solution: Use the engine oil grade specified in the vehicle manual and avoid mixing different brands of engine oil. 3. Engine misfire. Engine misfire means one or more cylinders are not functioning properly. Solution: Check the condition of each ignition coil and cylinder spark plug.
I just dealt with the issue of loud acceleration noise in my car last week. First, check the engine oil condition—aged oil can cause the engine to run roughly and produce roaring sounds. Next, inspect whether the air filter is clogged, as insufficient air intake can force the engine to work harder. Loose exhaust pipe connections can also cause abnormal noises. Last time, I found that a cracked exhaust pipe gasket was causing a sports-car-like roar during acceleration. Additionally, don’t forget to check the engine mount bushings—when they age, their damping effect weakens, and vibrations directly transmit into the cabin. Finally, if the vehicle’s mileage exceeds 80,000 km, the timing chain may have stretched and require replacement. I recommend troubleshooting from the easiest to the most complex tasks—changing the oil and oil filter yourself is straightforward, but other issues are best diagnosed by a professional mechanic.
