Where is the engine number located on a Golf?

[PatrickLee]

The engine number of a Golf is located on the engine block. The engine converts other forms of energy into mechanical energy, including reciprocating piston engines, external combustion Stirling engines, steam engines, jet engines, and electric motors. Benefits of cleaning the engine include: 1. Cleaning oil sludge in the oil passages. The engine body is filled with oil passages, and over time, sludge and other deposits may accumulate inside these passages. Engine cleaning agents can help remove these impurities, ensuring the proper functioning of the engine's lubrication system. 2. Cleaning carbon deposits on the piston rings. When the engine cleaning agent is added to the oil, it helps clean carbon deposits on the piston rings and inside the ring grooves as the oil spreads on the cylinder walls. 3. Maintaining the engine. By removing sludge and carbon deposits that affect the engine's normal operation, the engine's performance can be improved, and its service life extended.
