| Summary: | Alternative fuels are renewable sustainable and address socio-economic and environmental concerns. In this circumstance, this work is conducted in two stages. The first stage of the work involves, the preparation of nanoparticle (NP) blended fuels by adding 20, 40 and 60 ppm of multi-walled carbon nanotube (MWCNT) particles in dairy scum oil methyl ester (DiSOME) biodiesel using a mechanical homogenizer and ultrasonicator. Then, the steadiness characteristics of nanoparticle–mixed biodiesel fuels were studied under static state. In the next stage of the work, the effect of nanofluids on the attributes of combustion and emissions of aengine with 1-cylinder 4-stroke DI-direct injection),CI-compression ignition)which is run on DF-dual-fuel mode using DiSOME and PG-producer gas, has been examined. Investigation results indicated that at 80% load, DiSOME-PG combustion with 40 ppm of MWCNT nanoparticles provided 5.7% increased BTE, 23.5% decreased smoke opacity, 21.8% decreased HC, 22.4% decreased CO and 20.1% amplified NOx emissions related to the same fuel mixer but not with NPs. Adding NPs increased HRR - heat release rate and CP - cylinder pressure.
