LEADED GASOLINE Meaning and
Definition
-
Leaded gasoline, also known as leaded petrol, refers to a type of fuel used in internal combustion engines that contains the additive tetraethyl lead (TEL). It was widely used as a fuel for automobiles and other vehicles until its phase-out during the late 20th century. Leaded gasoline consists of a mixture of hydrocarbons derived from crude oil, blended with a percentage of TEL.
The purpose of adding lead to gasoline was primarily to improve engine performance by preventing knocking or pinging, which refers to the sound produced when uncontrolled combustion occurs in the engine cylinders. Tetraethyl lead acts as an anti-knock agent, effectively reducing engine knocking and thus enhancing fuel efficiency and overall engine power.
However, the use of leaded gasoline has been associated with severe environmental and health concerns. Combustion of leaded gasoline releases lead compounds into the atmosphere, which can contaminate soil, air, and water. Exposure to lead is toxic to humans, causing various health issues, especially in young children, such as neurological and developmental disorders. Consequently, many countries phased out and eventually banned the use of leaded gasoline in order to protect public health and the environment.
Today, leaded gasoline has largely been replaced by unleaded gasoline, which contains no tetraethyl lead or other lead compounds. The transition to unleaded gasoline has significantly contributed to reducing environmental pollution and improving air quality worldwide.

Etymology of LEADED GASOLINE
The word "leaded" in "leaded gasoline" refers to the addition of tetraethyl lead (TEL), which was a highly toxic compound used as an additive in gasoline. The use of TEL in gasoline began in the early 20th century as it improved fuel performance, prevented knocking in internal combustion engines, and increased fuel efficiency.
The term "leaded" comes from the fact that TEL contains lead, which was utilized to enhance the octane rating of the fuel. The purpose of adding lead was to reduce engine knocking by improving combustion characteristics. Lead also acted as a lubricant, protecting the valves of the engine. Hence, the term "leaded gasoline" emerged to describe this type of fuel.
However, due to the severe health and environmental hazards associated with lead, especially its emission into the atmosphere during combustion, the use of leaded gasoline has been almost entirely phased out in most countries.
