           B. carinata genotypes based on oil content and fatty acid composition.
           Genet et al. have generated information to plan crosses and maximize
           the use of genetic diversity and expression of heterosis [130]. Dorado et al.
           found negative effects of singular fatty acids, such as erucic acid, over
           alkali-catalyzed transesterification reaction [39]. These researchers
           described a low-cost transesterification process of B. carinata oil. An
           oil–methanol molar ratio of 1:4.6, addition of 1.4% of KOH, a reaction tem-
           perature in the range of 20–45 C, and 30 min of stirring are considered
           to be the best conditions to develop a low-cost method to produce biodiesel
           from B. carinata oil [39, 131]. Biodiesel from Ethiopian mustard oil could
           become of interest if a fuel tax exemption is granted [30]. When com-
           pared with petroleum diesel fuel, Cardone et al. have found that engine
           test bench analysis did not show any appreciable variation of output
           engine torque values, while there was a significant difference in specific
           fuel consumption data at the lowest loads. Biodiesel produced higher
           levels of NO concentrations and lower levels of particulate matter (PM),
                      x
           with respect to diesel fuel. Biodiesel emissions contain less soot [132].

           Crop description.  Camelina sativa L. Crantz—commonly known as
           gold-of-pleasure and camelina—belongs to the family Cruciferae and
           grows well in temperate climates (see Fig. 4.16). It is an annual oilseed
           plant and is cultivated in small amounts in France, and to a lesser
