How much compression does a small 80cc generator have?

A small 80cc generator typically has a compression ratio ranging from about 8:1 to 10:1. This means that the air-fuel mixture is compressed to one-eighth to one-tenth of its original volume before ignition. The exact compression can vary depending on the specific design and manufacturer of the generator. Higher compression ratiOS can lead to more efficient engine performance but may also require higher-octane fuel.
