Abstract

This study investigates the effects of hydrogen-assisted combustion of n-heptane on engine performance, combustion behavior, and emission characteristics. The simulation was performed on a diesel engine fueled by n-heptane with 10% and 20% hydrogen injection volumes. The combustion simulation was performed on a three-dimensional cylindrical sector, with the engine speed maintained at 2000 revolutions per minute (rpm) while the crank angle varied from 570° to 833°. A reaction mechanism was utilized to incorporate the phases of n-heptane and H₂ interaction and the CO and NOx formation processes. According to the modeling results, increasing hydrogen induction dramatically improves performance by raising the maximum cylinder pressure, brake thermal efficiency, and heat release rate. The cylinder pressure increases by 4.1% and 15.9% when 10% and 20% hydrogen are added to heptane, respectively. Adding 10% H₂ increases the thermal efficiency by 23.7%, and adding 20% H₂ increases it by 37%. Together with the contours of CO, CO₂, and NOx, the distribution of in-cylinder pressure illustrates the properties of the flow field. Both CO and CO₂ pollution have significantly decreased overall. When a 10% volume of H₂ was added, CO emissions dropped by 57.1%, and when a 20% volume of H₂ was added, they dropped by 64.2%. CO₂ emissions decreased by 25.1% with a 10% volume of H₂ and by 39.1% with a 20% volume of H₂. Moreover, more excellent combustion has resulted in a rise in NOx emissions.
