What are all the causes of engine shaking?

[McJoshua]

All the causes of engine shaking are: 1. Engine misfire; 2. Worn or loose engine mounts; 3. Carbon buildup; 4. Fuel system malfunction; 5. Poor valve sealing leading to operational issues. The function of an engine is: to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and push the pistons to perform work. The maintenance methods for an engine include: 1. Regularly changing the oil and oil filter; 2. Using lubricating oil of the appropriate quality grade; 3. Periodically cleaning the radiator; 4. Regularly replacing the air filter, oil filter, and fuel filter; 5. Maintaining good crankcase ventilation and cleaning it regularly; 6. Periodically cleaning the fuel system.
