Diesel is most commonly used a [[fuel]] for [[transportation]], specifically. Both diesel and gasoline have about the same ''[[energy density#fuel energy density\|energy density]]''; but because diesel has a higher ''[[density\|mass density]]'' than [[gasoline]], the same [[volume]] of diesel has more [[energy]] than gasoline. Diesel also allows for engines to run much higher [[Diesel vs gasoline engine#Ignition\|compression ratios]] (i.e. the ratio of the highest volume to the lowest volume in the compression chamber). Both, diesel's higher mass density and higher compression ratios, allows [[diesel engine]]s to be more [[efficiency\|energy efficient]] than their gasoline burning counterparts. Diesel engines are also different from gasoline in that they don't use [[spark plug]]s, instead achieving [[ignition]] through compression of the fuel (and a glow-plug when the engine is cold). Diesel engines work by having a [[piston]] pressurize [[air]], to heat it up (remember the [[ideal gas law]]: at a constant volume, increasing pressure increases the temperature). Fuel injectors then atomize the fuel, turning it into a [[gas]]. The heat from the air inside the chamber raises the [[temperature]] of the diesel gas until it ignites, which does [[work]] against a [[diesel engine#parts of a diesel engine\|piston]] in the chamber.

	Petrodiesel is the name for diesel that is derived from [[petroleum]]. This diesel usually must be refined to remove [[sulfur]] from it. Currently, petrodiesel is more common than biodiesel as a fuel. Petrodiesel is produced through a process called [[fractional distillation]], where crude [[oil]] is boiled, and its components separated. Because diesel has a higher [[boiling point]] than [[gasoline]], the gasoline separates from the [[crude oil]] sooner. This process allows [[oil refinery\|refineries]] to separate substances like diesel, [[kerosene]], and [[gasoline]] from each other.<ref>http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_pre_2011/rocks/fuelsrev3.shtml</ref>		Petrodiesel is the name for diesel that is derived from [[petroleum]].
