What Does Engine Sinking Mean?

[MadelynRose]

Engine sinking refers to a safety feature designed to prevent the engine from crushing the driver in the event of a severe collision. The reasons for engine starting difficulties include: 1. Too lean or too rich air-fuel mixture; 2. Fuel supply system or intake system malfunction; 3. Faulty spark plugs or ignition coils; 4. Severe carbon buildup in the engine; 5. Worn or loose engine mounts; 6. Insufficient cylinder pressure. The function of the engine is to convert the thermal energy of gasoline into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and 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.
