Petrolfuel

Petrolfuel is a broad term referring to gasoline used in spark-ignition internal-combustion engines. It is a refined fossil fuel derived from crude oil, produced through distillation and downstream refinery processes, and blended to meet regional performance and emission requirements. The hydrocarbon mix is diverse, including alkanes, cycloalkanes, and aromatics; additives improve detergency, corrosion resistance, and octane, while oxygenates such as ethanol may be blended in varying proportions in many markets (for example, E10 or higher).

Production and standards: Gasoline is produced as part of refinery output and formulated to meet specific performance and environmental specifications. The octane rating—often expressed as Research Octane Number (RON) and Motor Octane Number (MON) or as anti-knock index (AKI)—indicates resistance to engine knocking. Standards such as ASTM D4814 in the United States and EN 228 in the European Union govern composition, performance, vapor pressure, and labeling for different grades. Energy density for petrolfuel is about 34.2 megajoules per liter (roughly 46 megajoules per kilogram), with variations depending on formulation and additives.

Use, efficiency, and environmental aspects: Petrolfuel powers many light-duty vehicles, motorcycles, and other small engines. Engine design, octane, and fuel formulation influence efficiency and emissions. Burning petrolfuel releases carbon dioxide, nitrogen oxides, volatile organic compounds, and particulates, contributing to air pollution and climate change. Regulations promote cleaner blends, sulfur reductions, and evaporative controls. Alternatives include diesel, biofuels, electric propulsion, and hydrogen.

Safety: Petrolfuel is highly flammable; vapors can ignite in the presence of an ignition source. Proper storage, handling, and spill prevention are essential.
