What Causes Loud Engine Noise and Vibration?
3 Answers
Engine vibration and loud noise can be caused by: 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. Air intake system issues. 6. Normal reaction during cold starts. Introduction to automobile engines: 1. 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. 2. The term engine can refer either to the power generation device or the entire machine including the power unit.
This is quite common. If the engine sounds louder and shakes violently, I'd say it might be an issue with the ignition system—worn-out or weak spark plugs causing uneven combustion, which makes the engine shake. As for the noise, it could be due to a loose belt or an exhaust leak, amplifying the sound and making it sound like a tractor. Ignoring it could lead to faster wear and tear on engine components, or even damage internal parts. I recommend checking the ignition system first, maybe replacing the spark plugs, or listening for any screeching from the belt. Also, if the engine mounts are loose, it’ll shake like it’s dancing—tighten them with a wrench. In short, don’t delay—find a reliable mechanic to check it out to avoid accidents while driving.
I reckon the issue of loud engine noise and shaking is mostly due to internal engine problems, such as unstable combustion or cylinder misfiring—it's like walking unsteadily with a few bad legs. Exhaust system issues, like stuck valves or a faulty muffler, can also amplify the noise, making it sound like a roar. Don’t underestimate the shaking; if the engine mounts are worn or loose, you’ll feel the car vibrating while driving, affecting control. My advice is to maintain the engine regularly—changing the oil periodically can reduce wear and prevent carbon buildup. If this happens, try turning off the AC first; sometimes, load variations can reveal the problem. Addressing it promptly can save you big bucks.
