Oil usefulness.

Uses fractions obtained from petroleum-related fisisnya properties like boiling point and viscosity, and chemical properties.

Gasoline.
Gasoline is a transportation fuel that still plays an important role until now. Gasoline contains more than 500 types of hydrocarbons that have a chain C5-C10. Levels vary depending on the composition of crude oil and the desired quality. So, how is the use of petrol as fuel?

Gasoline as a fuel in motor vehicles.
Because gas burns only in the vapor phase, then the fuel must be evaporated in the carburetor before the cylinder is burned in vehicle engines. The energy generated from the combustion process of gasoline changed into motion through the following stages.

Combustion of gasoline is the desired result in a smooth drive to the decline of the piston. This depends on the accuracy of the combustion time for the amount of energy transferred to the piston to the maximum. Timeliness depends on the type of burning hydrocarbon chain which in turn will determine the quality of gasoline. Straight-chain alkanes in gasoline such as n-heptana, n-octane, and n-nonana highly flammable. This causes the combustion occurs too early before the piston reaches the right position. That places the sound of explosions known as knock (knocking). Arson too early also means there are remaining component of gasoline that has not burned so that the energy transferred to the piston is not the maximum. Branched-chain alkanes / alisiklik / aromatics in gasoline as isooktana not too easy to burn. Thus, fewer beats produced, and the energy is transferred to a larger piston.

Therefore, gasoline with a good quality should contain more branched chain alkanes / alisiklik / aromatic than straight chain alkanes. The quality is expressed by gasoline octane numbers.
