Evaluation of Dual Fuel Compression Ignition Engine Characteristics Powered With Camphor Oil–Diesel Blend With Hydrogen and Hexanol Enrichment—Response Surface Methodology Approach

ABSTRACT This research study aims to investigate the impact of hydrogen and hexanol enrichment on the energy exhaust environment, as well as the economic aspects of a Compression ignition (CI) engine powered with equally blended camphor oil and diesel fuel. The experiments are conducted on the single‐cylinder compression ignition engine at a constant supply of hydrogen at a 10 LPM flow rate. The experimental design matrix is developed by central composite, for the input, which varies from 50% to 100%, and the hexanol blending ratio, which ranges from 0% to 40% on a volume basis. Statistical models were evaluated using Analysis of Variance (ANOVA) and confirmed with a quadratic model. The experimental results show that the addition of hexanol to camphor oil–diesel blend and hydrogen elevates thermal efficiency, volumetric efficiency, exergy efficiency, cooling water exergy, carbon dioxide, nitrogen monoxide, and enviroeconomic loss. On the other hand, it drops the brake‐specific energy consumption, exhaust gas temperature, carbon monoxide, hydrocarbon, smoke, fuel exergy, exergy rate of engine exhaust, destructed exergy, entropy generation, exergoeconomic loss, and thermoeconomic loss. This research recommended the 40% hexanol blending ratio with camphor oil–diesel blend for future work with selective catalytic reduction for nitrogen monoxide and carbon dioxide emissions reductions.
