Research of operated with biodiesel urban bus's exhaust emissions by numeric method

This research work is investigated effects of using biodiesel as an fuel on emissions of bus diesel engine, which is use for public transport. Experimental study was done a diesel engine in static test mechanism and experimental values used in a computer program (Q-Basic) and were applied reel vehicle cycles with public transport. At tests, diesel fuel from petrol and bio diesel were used and both fuel?s performance and emission values were compared for both fuel.Keywords: Biodiesel, diesel engine emissions, public transport bus, reel vehicle cycles.
