Özet

Hydrogen has been proven to be a potential fuel alternative in the area of field of transportation and power generation. The study aimed to improve the efficiency of a dual-fuel engine running on a blend of biodiesels and hydrogen by optimizing operating parameters. This involved varying the injection pressure of pilot fuel (220, 240, and 260 bar) and adjusting engine load (ranging from 20 % to 100 % in increments of 20 % in five steps). The results indicate that maximum brake thermal efficiency of 28.11 % and liquid fuel substitution by 85 % when the injection pressure of pilot fuel was set to 240 bar at 100 % engine load. At 100 % load, setting the injection pressure of fuel to 240 bar resulted in a substantial drop in the emissions of carbon monoxide and hydrocarbons by 9.27 % and 47.61 %, respectively. The response surface methodology specified that the optimized value of the engine load and pilot fuel injection pressure was found to be 55.93 % and 242.731 bar, respectively for achieving optimum results of response variables from the engine.
