Gasoline is a product of oil refining, which is a fuel with low detonation characteristics. Up to 50% of gasoline is produced from crude oil. This value includes natural gasoline, gasoline cracking process, polymerization products, liquefied petroleum gases and all products used as industrial motor fuels.
Gasolines are intended for use in piston internal combustion engines with forced ignition (spark). Depending on the purpose, they are divided into automotive and aviation.
Despite the differences in the conditions of use, automobile and aviation gasolines are characterized mainly by general quality indicators determining their physicochemical and operational properties.
Modern automotive and aviation gasoline must meet a number of requirements that ensure economical and reliable engine operation, and operating requirements: have good evaporability that allows to obtain a homogeneous air-fuel mixture of optimal composition at any temperature; have a group hydrocarbon composition that ensures a stable, detonative-free combustion process in all engine operating modes; do not change their structure and properties during long-term storage and do not adversely affect the parts of the fuel system, tanks, rubber products, etc. In recent years, the ecological properties of the fuel have become the main focus.
