What are the causes of severe engine vibration?
2 Answers
Engine vibration can be caused by: 1. Overly advanced ignition timing; 2. Excessive carbon buildup in the engine; 3. Overheating of the engine. An engine is a machine that converts other forms of energy into mechanical energy. The first external combustion engine was invented by R. Stirling of Scotland, UK, and later improved by Watt into the steam engine. The term "engine" can refer to both the power generation device and the entire machine including the power unit (such as gasoline engines and aircraft engines). Engine types include internal combustion engines (e.g., gasoline engines), external combustion engines (e.g., Stirling engines, steam engines), gas turbines (used in racing cars), electric motors, etc.
As someone who frequently works on cars, engine vibration issues need to be diagnosed from several angles. The engine mounts in older vehicles are most prone to problems - when the rubber deteriorates, they can't dampen vibrations properly, causing excessive engine movement. Spark plugs that have reached the end of their lifespan cause uneven ignition, particularly noticeable during idle. Fuel system issues like clogged injectors creating uneven fuel delivery can also cause this. Mechanical components such as worn piston connecting rods disrupt engine balance. A failing idle control module causing speed fluctuations can induce shaking too. I remember a friend who delayed replacing spark plugs to save a few hundred yuan, only to have the excessive vibration damage the crankshaft, doubling the repair costs. Always pay attention to abnormal vibrations during daily driving and get professional inspection promptly - small issues can escalate into major problems.
