The early 20th century also saw the start of the use of vegetable oil as a fuel in diesel engines and in heating oil burners. Rudolf Diesel designed his engine to run on vegetable oil. The idea, he hoped, would make his engines more attractive to farmers who had a source of fuel readily available.
Industrial machines for extracting oil mechanically are call expellers. Many expellers add heat and pressure, in order to increase the amount of oil extracted. If the temperature does not exceed 120 °F, the oil can be called "cold-pressed". [3] In modern vegetable oil production, oils are usually extracted chemically, using a solvent such as ...
A number of oils are used for biofuel (biodiesel and Straight Vegetable Oil) in addition to having other uses. Other oils are used only as biofuel. [note 4] [147] Although diesel engines were invented, in part, with vegetable oil in mind, [148] diesel fuel is almost exclusively petroleum-based. Vegetable oils are evaluated for use as a biofuel ...

Oleochemistry is the study of vegetable oils and animal oils and fats, and oleochemicals derived from these fats and oils. The resulting product can be called oleochemicals (from Latin: oleum "olive oil"). The major product of this industry is soap, approximately 8.9×10 6 tons of which were produced in 1990.

The World production of vegetable oil seed is forecast to be 418 million tonnes in 2008/09. After pressing this will make 131 million tonnes of vegetable oil. [22] Much of this is from Oil Palm, and palm oil production is growing at 5% per year. At about 7.5 lb/USgal (900 g/L) this is about 38 billion USgallons (144 billion L).
