What is the compression ratio of the Volkswagen Lavida 1.6 engine?

[MacLilliana]

The compression ratio of the Volkswagen Lavida 1.6 automatic transmission engine is 10.8. Introduction to Compression Ratio: The compression ratio indicates the degree to which the gas in the cylinder is compressed when the piston moves from the bottom dead center to the top dead center. The compression ratio is one of the important parameters of an engine. In modern automotive engines, the compression ratio for gasoline engines is generally between 8 and 11 due to the limitation of knocking. Effect of Compression Ratio on Operating Temperature: When the operating temperature is too high, the air-fuel mixture entering the combustion chamber absorbs excessive heat, which may cause spontaneous ignition or pre-ignition, leading to knocking. This can result in engine power loss and damage to mechanical components. Conversely, if the temperature is too low, the vaporization of the air-fuel mixture is poor, leading to inefficient combustion. Unvaporized gasoline may condense on various parts of the cylinder wall, forming carbon deposits or floating in the oil ring.
