Abstract
The corrected abstract is as follows.This article aims to study the benzyl alcohol premixing effect on the 5E concept of compression ignition engines powered with a lemongrass oil-diesel blend. The central composite approach is used to create the experimental matrix for the load (50–100%) and benzyl alcohol premixing ratio (0–20%). The experiment uses a computerized compression ignition, water-cooled, single-cylinder, naturally aspirated, four-stroke engine. The statistical model is tested using analysis of variance and confirmed at the 95% confidence level. Quadratic and linear models are created, and regression equations provide surface plots to analyse load–premixing ratio interaction on output response. Premixing of benzyl alcohol at 20% at maximum loads confirms 31.09%, 14.95%, 31.09%, 39.91%, 17.26%, 11.06%, 7.59%, 36.61%, and 4.34% higher enviroeconomic loss, thermal efficiency, brake-specific carbon dioxide, brake-specific nitrogen monoxide, cooling water exergy, sustainability index, volumetric efficiency, and exhaust gas temperature. It also has lower exergoeconomic loss, thermoeconomic loss, brake-specific energy consumption, brake-specific carbon monoxide, smoke opacity, brake-specific hydrocarbon fuel exergy, exhaust gas exergy, destructed exergy, and entropy generation by 23.64%, 30.4%, 17.50%, 13.6%, 81.30%, 18.1%, 27.77%, and 27.77%, respectively. It is necessary to control nitrogen monoxide using exhaust gas recirculation or selective catalytic reduction technology in future work.
