What Causes the Engine Fault Light to Illuminate and the Engine to Shake?

[Kirsten]

Engine shaking accompanied by the illumination of the fault light can be attributed to the following reasons: 1. Poor combustion of the air-fuel mixture in the engine; 2. Malfunctions in the operation of spark plugs, high-voltage wires, and ignition coils; 3. Abnormal fuel supply pressure and faults in the intake pressure sensor. The function of the engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing the expansion of gases that push the pistons to perform work. The engine consists of: 1. The valve train; 2. The crankshaft and connecting rod mechanism; 3. The ignition system; 4. The cooling system; 5. The lubrication system; 6. The starting system; 7. The fuel supply system. Methods for engine maintenance include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning the radiator to remove scale; 4. Periodically removing carbon deposits from the engine; 5. Regularly replacing the three automotive filters (air, oil, and fuel); 6. Maintaining reasonable engine speeds.
