What Gasoline Corresponds to Motorcycle Compression Ratio?
1 Answers
Motorcycle engine compression ratio is 9.5:1, here are the relevant details: Compression ratio: The minimum working volume of the cylinder, which is the total volume above the piston when the piston is at top dead center, is called the combustion chamber volume, denoted as Vc; while the maximum volume of the cylinder when the piston is at bottom dead center, which is the total volume above the piston, is called the cylinder total volume, denoted as Va. Gasoline octane rating: The high or low number only indicates the size of the gasoline's octane rating, and different octane ratings should be selected based on the engine's compression ratio. Mid-range cars with a compression ratio between 8.5-9.5 should generally use 93 octane gasoline; cars with a compression ratio greater than 9.5 should use 97 octane gasoline.
