What does engine number mean?

[LukasDella]

Engine number refers to the engine serial number. The engine number typically includes information such as the engine model, production date, and place of origin code. Each engine has a unique serial number, making it a crucial piece of vehicle documentation that facilitates engine management by manufacturers and vehicle administration departments. Special attention should be paid to changes in the engine number during routine maintenance or engine replacement. Below is relevant information about engines: 1. Engine components: valve train; crankshaft connecting rod mechanism; ignition system; cooling system; lubrication system; starting system; fuel supply system. 2. Engine function: generates power by fully burning fuel in the cylinders; determines the vehicle's power performance, fuel efficiency, stability, and environmental friendliness. 3. Engine maintenance methods: use qualified engine oil; use qualified coolant and antifreeze; regularly clean radiator scale; regularly remove engine carbon deposits; regularly replace the three automotive filters; maintain reasonable engine speed.
