The effect of humidification of the air on the performance of a compression ignition engine operating on diesel, biodiesel with nano additives was investigated. The experiment was carried out on a single-cylinder, four-stroke, naturally aspirated water-cooled, direct injection Ricardo (E6/US) diesel engine at a constant speed of 1800 rpm, and varying loads. A mixture of Biodiesel (waste cooking oil) and diesel fuel by four ratios (B5, B10, B15, and B20) was used in the experiment. Besides, five concentrations of Iron oxide nanoparticles (Fe2O3, with particle size 20 nm) as fuel-additives were prepared (10 ppm, 30 ppm, 50 ppm, 70 ppm, and 100 ppm), and added to the test fuels (Bio-Diesel).  Taguchi Method by DOE was used for the optimization in this investigation. The results of Taguchi Method experiments identified the biodiesel (B20), nano additive (100 ppm), relative humidity (65%). The experimental results manifested that BTE improved by 17.62% and BSFC decreased by 12.72%, while NOx and PM reduced by 8.45%, 24.17%, respectively.

This study aims to find the optimum performance and emission characteristics of single cylinder variable compression ratio (VCR) engine with different blends of Annona methyl ester (AME) as fuel. The performance parameters such as specific fuel consumption (SFC), brake thermal efficiency (BTE), and emission levels of HC, CO, Smoke, and NO x were compared with the diesel fuel. It is found that, at compression ratio of 17: 1 for A20 blended fuel (20% AME + 80% Diesel) shows better performance and lower emission level which is very close to neat diesel fuel. The engine was operated with different values of compression ratio (15, 16, and 17) to find out best possible combination for operating engine with blends of AME. It is also found that the increase of compression ratio increases the BTE and reduces SFC and has lower emission without any engine in design modifications.
