What type of fuel should be used for motorcycles with a compression ratio greater than 11?
1 Answers
You can use 97-octane gasoline. Engine compression ratio: Generally speaking, the higher the compression ratio of an engine, the smaller the volume of the combustible mixture being compressed, resulting in greater power and lower fuel consumption. However, the engine's compression ratio must be matched with another indicator, which is the gasoline's anti-knock index, also known as the octane number, or the gasoline grade. Types of fuel: Currently, the fuel market abroad offers gasoline in three grades: 93, 95, and 98. Engine compression ratios are also designed with reference to these three grades, so there are not many engines that are compatible with 90-octane gasoline.
