What is the mechanism behind engine shaking faults?

[DeAlina]

Engine shaking faults occur due to the following mechanisms: 1. Poor combustion state. 2. Engine knocking, poor fuel quality. 3. Dirty engine cylinder interiors, with accumulated carbon deposits, etc. Below are the methods to address engine shaking: 1. Replace the air filter. The air filter is designed to protect the engine and reduce wear, typically requiring replacement around 10,000 kilometers. 2. Replace the spark plugs. After 30,000 to 40,000 kilometers of use, the ignition efficiency of spark plugs significantly decreases, affecting ignition. 3. Adjust the water temperature. High engine water temperature can cause early ignition timing, changes in the air-fuel mixture ratio, thinning of engine oil viscosity, and reduced lubrication performance. 4. Clean the fuel injectors. Gum in gasoline can clog the injector nozzles, leading to inconsistent fuel injection among injectors and uneven cylinder operation. 5. Clean carbon deposits, oil sludge, the throttle body, and the idle speed valve. Over time, the intake ports can become clogged with carbon deposits and oil sludge, obstructing airflow and affecting idle stability.
