What are the reasons for severe shaking when a car is just started?
1 Answers
Car shaking severely when just started is caused by: 1. Dirty throttle body or excessive carbon buildup in the fuel injectors leading to shaking; 2. Aging engine mounts also causing vibration; 3. Low cylinder compression; 4. Untimely replacement of spark plugs; 5. Engine shaking due to low fuel pressure; 6. Broken high-voltage wires; 7. Dirty or clogged air filter not replaced in time. The principle of car starting is to transition the engine from a stationary state to an operational state, using external force to rotate the engine's crankshaft, starting the internal combustion engine, igniting the combustible gas in the cylinders, initiating the working cycle, with the crankshaft beginning to rotate under external force until the engine runs.
