Benzin

Benzin is the German word for gasoline (also called petrol in some countries), a volatile and flammable liquid used primarily as fuel for spark-ignition internal-combustion engines in cars, motorcycles, and small equipment. It is a refined petroleum product produced from crude oil through distillation and blending to meet specifications for octane, volatility, and emissions. Gasoline is a complex mixture of hydrocarbons, typically in the C4–C12 range, plus additives such as detergents, antioxidants, corrosion inhibitors, and octane boosters. In many markets it is blended with ethanol (for example E10 or E85) to improve octane and reduce net petroleum use.

Historically, some gasoline included tetraethyl lead as an additive to raise octane, but leaded gasoline has been phased out in most regions due to health and environmental concerns. Modern fuels are largely lead-free in passenger-vehicle markets. The octane rating of gasoline indicates its resistance to knocking in engines; common grades include regular and premium, with higher octane grades used in higher-performance engines.

Applications and alternatives: The primary use of Benzin is powering light-duty vehicles with gasoline engines. It is also used in some lawn and garden equipment and other small engines. In aviation, a distinct product known as avgas is used. Diesel and alternative fuels (such as biodiesel or electricity) are used for other vehicle segments.

Environmental and health considerations: Combustion releases carbon dioxide, carbon monoxide, nitrogen oxides, and other pollutants. Gasoline vapors are volatile and can pose health risks; benzene, a carcinogenic component found in small amounts in some fuels, is regulated in many regions. Regulations also address emissions control, fuel formulation, and vapor recovery at fueling facilities.

Safety and storage: Benzin is highly flammable; it should be stored in approved containers away from heat, sparks, and open flames, and spills must be cleaned promptly to prevent soil and groundwater contamination.
