Abstract: An experimental investigation was accomplished for the effect of SiO2 nanoparticles (SNP) addition on performance and emissions features of a four-stroke single cylinder variable compression ratio diesel engine. The SNP were mixed with pure diesel in a dosage of 5mg, 10mg, 15mg, 20mg, and 25mg. These test fuels were tested at various engine loads of 2kW, 4kW, 6kW, 8kW, 10kW and 12kW at a speed of 1500 rpm with 18 C.R. The results shows that the maximum enhancement in brake thermal efficiency (BTE) achieved was 15.16% and minimum reduction of 14.28% in brake specific fuel consumption (BSFC) was noticed when correlated to neat diesel fuel at full load condition. The emissions of NOX, CO, HC, and smoke opacity (PM) for 20Si600DF (20 mg SNP+20mg CTAB+600 ml diesel) test fuel were significantly decreased by 77.13%, 82.14%, 93.94%, and 33.41% as compared to pure diesel fuel at full load condition. The results reported that 20Si600DF at 18 CR value shows the optimal improvement in performance with minimum emissions. Finally, it can be concluded that SiO2 nanoparticles act as a promising additive which can be added in diesel fuel in order to reduce emissions and enhance performance parameters without any engine modifications.
