The molecular formula of biobutanol is C4H10O.
It is primarily used as a biofuel.
Biobutanol can be blended up to 85% with gasoline for use in spark ignition engines without modification.
Good combustion is achieved when fuel and air are mixed in the correct ratio.
Liquid or solid fuel must be vaporized to form a gas before it can be burned.
Combustion is the rapid oxidation of fuel, releasing heat and light.

The main purpose of fuel in agricultural mechanization is to power farm machinery.
Combustion involves a combustible substance reacting with oxygen and releasing energy.
Fuel efficiency is measured primarily by its calorific value.
Gasoline, commonly derived from crude oil, is typically used in vehicles.

Gasoline is used in spark-ignition engines.
Diesel fuel is typically used in compression-ignition engines.
Liquefied petroleum gas (LPG) is a type of gasoline consisting of propane and butane.
Methane is the major component of natural gas.
The calorific value of kerosene ranges from 4000 to 5000 kcal/kg.
Butane weighs approximately 2.5 times more than air.

A gas producer converts solid fuel into a combustible gas called producer gas.
LPG, being heavier than air, can flow on the ground and be ignited even at a distance.
