Chemical properties of gasoline components

Hydrocarbon-based fuels which are gasoline, diesel, natural gas, and liquefied petroleum gas (LPG) have been generally used in the diesel and gasoline engines as a fuel. In this study, hydrocarbon-based fuels such as alkanes (paraffins), naphthenes (cycloparaffins), alkenes (olefins), alkynes (acetylenes), and aromatics (benzene derivatives) have been classified. Their molecular structure and properties have been comprehensively explained. In addition to this, some of the important fuel properties of the commonly used fossil-based fuels such as gasoline and diesel in the internal combustion engine have been evaluated. Thus, hydrocarbon derivative fuels which are diesel, gasoline, natural gas, and liquefied petroleum gas (LPG) have been investigated as an internal combustion engine fuel. Their physical and chemical properties were explained and compared to each other. Octane number and cetane number substantially affect the bränsle ignition delay period and self-ignition t

Chemical Composition of Gasoline and Diesel and Differences in Their Engine Operating Regimes

The most widely used fuels for internal combustion engines, gasoline and diesel, distinguish themselves by their unique chemical composition, which profoundly influences the operation and performance of the engines that use them. Let's first explore how they differ chemically.

Gasoline, Chemical Structure

Gasoline is a lightweight and volatile fuel, primarily composed of short-chain hydrocarbons. Short-chain hydrocarbons are molecules consisting solely of carbon and hydrogen atoms, forming the basic structure of many organic compounds. In this context, "chain" refers to a succession of carbon atoms with single or double chemical bonds between them, along with hydrogen atoms attached to the carbon atoms.

In general, the length of the hydrocarbon chain influences the chemical and physical properties of a molecule. Short-chain hydroca

Properties of Gasoline Fuel

Gasoline or petrol is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most petrol engines or spark-ignited internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of crude oil in petroleum oil refinery enhanced with a variety of additives. The typical gasoline composition percentage of hydrocarbons (% volume) is as follows: % alkanes; % alkenes; % isoalkanes; % cycloalkanes; l-4% cycloalkenes; and % total aromatics (% benzene). Gasoline streams from various plants of the petroleum refinery are blended to produce, petrol of desired specifications.

Gasoline is mainly used as a transportation fuel around the world. Gasoline uses include cars, motorbikes, sport utility vehicles, light trucks, small air crafts, boats, small vehicles, equipment and tools used in the construction industry, electricity generators, etc.

Gasoline is typically a blend of various refiner
