Diesel or Diesel fuel is a specific fractional distillate of fuel oil (mostly petroleum) that is used as fuel in a diesel engine invented by German engineer Rudolf Diesel. The term typically refers to fuel that has been processed from petroleum, but increasingly, alternatives such as biodiesel or biomass to liquid (BTL) or gas to liquid (GTL) diesel that are not derived from petroleum are being developed and adopted.

Petroleum diesel


Diesel is produced from petroleum, and is sometimes called petrodiesel (or, less seriously, dinodiesel) when there is a need to distinguish it from diesel obtained from other sources such as vegidiesel (biodiesel) derived from pure (SVO) or recycled waste (WVO) vegetable oil. As a hydrocarbon mixture, it is obtained in the fractional distillation of crude oil between 250 °C and 350 °C at atmospheric pressure.

The density of diesel is about 850 grams per liter whereas gasoline has a density of about 720 g/l, or about 15% less. When burnt, diesel typically releases about 40.9 megajoules (MJ) per liter, whereas gasoline releases 34.8 MJ/L, also about 15% less. Diesel is generally simpler to refine than gasoline and often costs less (although price fluctuations often mean that the inverse is true; for example, the cost of diesel traditionally rises during colder months as demand for heating oil, which is refined much the same way, rises).

Threat Reduction Agency marks 10 years of operations
afnews@afnews.af.mil (Jim Garamone) Tue, 07 Oct 2008 14:51:00 -0500
It is an agency that seems tailor-made to combat the threats the United States faces today: nuclear proliferation, chemical weapons and the possibility of genetically modified diseases.   But the Defense Threat Reduction Agency was formed when Americans still thought there was such a thing as a "peace dividend" and few had ever heard of al-Qaida. When then-Defense Secretary William S. Cohen tried to draw attention to the threat of biological warfare, some were very skeptical of this focus. more...
