Key Points

This investigation aims to assess how H2/NH3/diesel fuel blends affect engine performance and exhaust emissions.
Used simulation to evaluate impact of different fuel blends.
Incorporated 5% exhaust gas recirculation (EGR) in tests.
Analyzed combustion efficiency, peak pressures, and temperature.
Hydrogen blends significantly enhance combustion efficiency and peak temperatures.
EGR application results in lowered peak temperatures.
Blending hydrogen improves heat transfer in the combustion process.

Implication

Simulation compares hydrogen, ammonia, and diesel blends in engines, showing effects on efficiency and emissions.

Abstract

• Hydrogen enhances combustion efficiency, peak pressures, and temperature significantly. • Hydrogen-rich blends improve heat transfer and temperature profiles. • Study compares hydrogen, ammonia, and diesel fuel blends. • EGR lowers peak temperature.
