What type of fuel should be used for a compression ratio of 10?
1 Answers
97# gasoline is required. Below is the relevant information: 1. Minimum working volume of the cylinder: This refers to the total volume above the piston when it is at the top dead center, known as the combustion chamber volume, denoted as Vc. The total volume above the piston when it is at the bottom dead center, which is the maximum volume of the cylinder, is called the total cylinder volume, denoted as Va, i.e., ε=Va/Vc. 2. Compression ratio: The compression ratio indicates the degree to which the gas in the cylinder is compressed when the piston moves from the bottom dead center to the top dead center. The compression ratio is one of the important parameters of an engine. For modern automotive engines, due to the limitation of knocking, the compression ratio of gasoline engines is generally between 8-11. Diesel engines, not limited by knocking, generally have a compression ratio between 12 and 22.
