Transforming vegetable oil into biodiesel is not very hard or costly, so there is a profitable arbitrage situation if vegetable oil is much cheaper than diesel. Diesel is also made from crude oil, so vegetable oil prices are partially linked to crude oil prices. Farmers can switch to growing vegetable oil crops if those are more profitable than ...
Some vegetable oil blends are used in unmodified vehicles, but straight vegetable oil often needs specially prepared vehicles which have a method of heating the oil to reduce its viscosity and surface tension, sometimes specially made injector nozzles, increased injection pressure and stronger glow-plugs, in addition to fuel pre-heating is used ...
The heat of combustion of kerosene is similar to that of diesel fuel; its lower heating value is 43.1 MJ/kg (around 18,500 Btu/lb), and its higher heating value is 46.2 MJ/kg (19,900 Btu/lb). [15] ASTM International recognizes two grades of kerosene: 1-K (less than 0.04% sulfur by weight) and 2-K (0.3% sulfur by weight). [16]
A tank of diesel fuel on a truck. Diesel fuel, also called diesel oil, heavy oil (historically) or simply diesel, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel.
Waste vegetable oil that has been filtered. Vegetable oil can be used as an alternative fuel in diesel engines and in heating oil burners. When vegetable oil is used directly as a fuel, in either modified or unmodified equipment, it is referred to as straight vegetable oil (SVO) or pure plant oil (PPO).

energy/mole of fuel; energy/mass of fuel; energy/volume of the fuel; There are two kinds of enthalpy of combustion, called high(er) and low(er) heat(ing) value, depending on how much the products are allowed to cool and whether compounds like H 2 O are allowed to condense. The high heat values are conventionally measured with a bomb calorimeter ...
Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.
