What Causes Excessive Engine Vibration and Noise?
2 Answers
The causes of excessive engine vibration and noise are: 1. Dirty throttle body or excessive carbon buildup in fuel injectors; 2. Worn or loose engine mounts; 3. One or more cylinders not functioning properly; 4. Fuel system malfunction; 5. Intake system failure; 6. Normal reaction during cold starts. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. The term engine can refer to either the power generation device or the entire machine including the power unit.
When driving, I experienced severe engine shaking and loud noise—it felt like the car was dancing, which was really annoying. The main reasons could be aging spark plugs or gap issues, causing irregular ignition and unstable combustion. Alternatively, it might be a fuel system problem, such as clogged fuel injectors, leading to uneven fuel supply and shaking. A dirty air filter can also obstruct airflow, making the engine struggle for air and increasing noise significantly. Last month, I dealt with a similar issue—replacing the spark plugs made it much quieter. Don’t neglect routine maintenance; regularly cleaning the intake system can prevent carbon buildup that causes shaking. If the engine mounts are loose or damaged, vibrations transfer directly to the body, making it even noisier. I recommend finding a reliable repair shop for a check-up—don’t tough it out. Safety first ensures peace of mind while driving.
