The article presents the results of comparative motor research on FAME biofuels using diesel engine VALMET 320 DMG. Energy (ηe, be) and environmental parameters (CO2, CO, NOx, HC, SM) of the engine were estimated. The obtained data on motor research into new biofuels show that the properties of Camelina sativa biofuels are as good as those observed in standardized rapeseed methyl ester biofuels. In case of using Camelina sativa biofuels blends VME and ZME at different engine loads, exhaust emissions from gas smoke could be reduced up to 10% and 30% accordingly comparing with mineral diesel. When the engine is fueled with tested biofuel blends, carbon monoxide emissions decrease by about 5–6%, and the factor for effective performance increases by approximately 4%. In all range of engine loads, an increase in nitrogen oxide emissions reaching 2–3% was observed. In all cases of using biofuel blends, carbon dioxide emissions keep close to the application of mineral diesel.
