The knock and rough limit crossover occurs at ~13.5:1 for E85 and ~12:1 for gasoline. E85/NH3 has higher knock limit and allows for a higher maximum compression ratio and thermal efficiency. Gasoline/NH3 has a lower roughness limit and allows for a slightly more fuel mixture flexibility.
Figures and tables showing how the properties of liquid and gaseous ammonia changes along the boiling/condensation curve (temperature and pressure between triple point and critical point conditions). An ammonia phase diagram are included.
1 Δεκ 2020 · Co-firing NH 3 with diesel can overcome the high auto-ignition temperature and narrow flammability limits of pure NH 3, while exploit its advantage. This study presents the auto-ignition properties of NH 3 /diesel binary fuel, at various NH 3 blending ratios (10%, 30% and 50%) in a rapid compression machine.
Ammonia (NH 3) is one of the important ways for diesel engines to achieve carbon neutrality. Ammonia’s energy density by volume is nearly double that of liquid hydrogen, making it easier to ship and distribute. Ammonia has a well-developed infrastructure and can also be used as a hydrogen energy carrier.
A thorough evaluation of each potential alternative fuel against the ideal fuel criteria listed, leads to the choice of NH3 (anhydrous ammonia) as the leading alternative fuel candidate. NH3 has been called “the other hydrogen” and exhibits all of the advantages of hydrogen.
Four of the most discussed alternative fuels are briefly compared here with their advantages and disadvantages – LNG, Methanol, Ammonia, Hydrogen.
