), and particulate matter, contributing to global warming and smog.

Breaking down large, heavy hydrocarbon molecules into the smaller ones that make up gasoline. This is often done using heat (thermal cracking) or catalytic cracking to improve yields.

The quality of gasoline is measured by several critical factors: Malserc - GASOLINE

The initial separation of crude oil into different "fractions" based on boiling points.

Hydrocarbons containing at least one carbon-carbon double bond. Naphthenes: Cyclic alkanes. ), and particulate matter, contributing to global warming

This measures a fuel's resistance to "knocking" or "pinging" during combustion. Higher octane numbers indicate the fuel can withstand more compression before detonating.

Gasoline is a complex mixture of hundreds of different hydrocarbons. Most are relatively small, with 4 to 12 carbon atoms per molecule. The primary components include: The quality of gasoline is measured by several

This determines how easily the liquid turns into a gas. High volatility is needed for cold starts, but it must be balanced to prevent "vapor lock" in hot weather.
