A compression ratio of 9.8 is most suitable for 95 octane gasoline. Compression ratio: The ratio of the maximum volume of the cylinder at bottom dead center to the minimum volume of the cylinder at top dead center is the compression ratio. Here is an introduction to compression ratio: 1. The compression ratio is the ratio of the volume of the cylinder before compression to the volume of the compressed air-fuel mixture. More specifically, it is the ratio of the maximum volume of the cylinder when the piston is at bottom dead center to the volume of the cylinder when the piston is at top dead center. 2. The compression ratio is closely related to engine performance. Generally, a low compression ratio refers to a ratio below 10, while a high compression ratio is above 10. Relatively speaking, the higher the compression ratio, the greater the engine power. 3. Generally speaking, when other engine designs remain unchanged, a higher compression ratio results in greater power, higher efficiency, and better fuel economy.
