Analysis of the Ecological Parameters of the Diesel Engine Powered With Biodiesel Fuel Containing Methyl Esters From Camelina Sativa Oil

Abstract

The article explores the possibilities of using fatty acid methyl esters derived from the oil of a new species of oily plant Camelina sativa not demanding on soil. The performed research on the physical and chemical properties of pure methyl esters from Camelina sativa show that biofuels do not meet requirements for the biodiesel fuel standard (LST EN 14214:2009) of a high iodine value and high content of linoleic acid methyl ester, so they must be mixed with methyl esters produced from pork lard the content of which in the mixture must be not less than 32%. This article presents the results of tests on combustion emission obtained when three‐cylinder diesel engine VALMET 320 DMG was fuelled with a mixture containing 30% of this new kind of fuel with fossil diesel fuel comparing with emissions obtained when the engine was fuelled with a fuel mixture containing 30% of conventional biodiesel fuel (rapeseed oil methyl esters) with fossil diesel fuel. The obtained results show that using both types of fuel, no significant differences in CO and NOx concentrations were observed throughout the tested load range. When operating on fuels containing methyl esters from Camelina sativa, HC emissions decreased by 10 to 12% and the smokeness of exhaust gas by 12 to 25%.

Comparative Investigations Into Energetic and Ecological Parameters of Camelina-Based Biofuel Used in the 1z Diesel Engine

“…Changes in the ecological parameters obtained in the tests when diesel fuel is replaced by biofuels B30 (RME) and B30 (WCME and SCME) correlates well with comparative investigations into the same fuels in diesel engine VALMET DMG 320 (Lebedevas et al 2010).…”

The fuels, including certified methyl esters of fatty acids and other biofuels produced in Lithuania, are used.…”

Combustion characteristics of diesel fuel on one cylinder diesel engine using clove oil, eugenol, and eugenyl acetate as fuel bio-additives

“…Bio-fuel (or biodiesel) is the most widely used alternative fuel that have been developed in recent times due to its cost and its particular characteristics including environmental friendly fuel, less polluting, and renewable [2][3][4][5][6][7][8]. Methanol and ethanol are good candidates as alternative fuel since they have several physical and chemical properties similar to diesel fuel [9].…”
