Description

Rapeseed (Brassica napus), also known as rape, oilseed rape, rapaseed (and, in the case of one particular group of cultivars, ), is a bright-yellow flowering member of the family Brassicaceae (mustard or cabbage family). Rapeseed oil is cultivated mainly for its oil-rich seed, the third-largest source of vegetable oil in the world.
 
Rapeseed oil is used as diesel fuel, either as biodiesel, straight in heated fuel systems, or blended with petroleum distillates for powering motor vehicles. Biodiesel may be used in pure form in newer engines without engine damage and is frequently combined with fossil-fuel diesel in ratios varying from 2% to *0% biodiesel.
