Performance of a Diesel Engine Generator Fuelled with Blends of Diesel Fuel and Waste Used Oil

摘要

An Experimental investigation introduced on a diesel generator to examine the effects of addition used lubricating oil (ULO) on diesel engine generator combustion. This paper presents experimental results of utilizing blends of ULO as a supplementary fuel with diesel fuel (DF), to provide a way to use this waste fuel as alternative or renewable energy. Different experiments were investigated to show the impacts on the emissions and the performance of diesel engine generator, blends of percentage 5%ULO-95%DF (S2), 10% ULO-90%DF (S3) and 20%ULO-80DF (S4) with blend of 100%diesel fuel (DF) (S1) are used as an experimental samples. For this experimental study a test carried out on a test engine. A diesel engine generator (DEUTZ / F2L-511), compression-ignition engine with double cylinder, 4-stroke naturally-aspirated and direct-injection was used. Comparative study between the four sample on the performed of engine emissions and performance; experiments were introduced at different engine operating loads. Results show that the use of ULO is promising supplementary fuel for diesel engines generator, especially at a part load with some slight deficiency in the engine performance at a full load.
