Blended biofuel with linseed oil for diesel engines
The study examines specific features of biodiesels made with linseed oil, physicochemical characteristics of petrodiesels, linseed oil, and their combinations in various proportions. The results of experimental studies of a D-245.12C type diesel engine operating on blends of conventional diesel fuel and linseed oil are presented. A relationship between the fuel efficiency and exhaust fume toxicity, and the composition of the blended biofuel has been determined, based on which a method for optimization of the blended biofuel composition has been proposed. The method is based on composing a multiplicative generalized optimization criterion as the product of two partial criteria. The first criterion characterizes the conditional efficiency coefficient of the diesel engine, while the second one refers to nitrogen oxide mass emissions per unit. The optimal composition of the blended biofuel has been determined.
