The compression ratio of the Dayang 150adv scooter engine is 9.8:1. The role of compression ratio: It is the ratio of the total cylinder volume to the total combustion chamber volume in a motorcycle. Generally, engines with higher compression ratios have stronger explosive power. Vehicles with the same displacement but higher compression ratios accelerate better and may have lower fuel consumption. Notes on compression ratio: Different compression ratios result in varying levels of knocking and differences in the completeness of gasoline combustion, which determines the choice of gasoline octane rating. Generally, engines with higher compression ratios use higher-quality gasoline, leading to better fuel utilization. Vehicles with higher compression ratios also require gasoline with higher octane ratings, which is why different motorcycles need to use different types of gasoline.
