2023年10月1日 · Ammonia represents a crucial fuel option for achieving zero carbon emissions in the internal combustion engine sector in the future. However, due to its combustion inertness, ammonia requires highly reactive fuels as combustion promoters to enhance its combustion.

Ammonia is currently receiving more interest as a carbon-free alternative fuel for internal combustion engines (ICE). A promising energy carrier, easy to store and transport, being liq., and non-carbon-based emissions which make ammonia a green fuel to decarbonize ICE and to reduce greenhouse gas (GHG) emissions.

Ammonia IC Engine Overview Compression Ignition • 100% NH 3 requires high compression ratio (CR > 35:1) • Dual-fuel strategies • <10% Pilot diesel injection • Multiple injection strategies for emissions reduction Spark Ignition • Laminar flame speed low for ammonia alone • Blending with hydrocarbon fuel • H 2-NH 3

2022年7月21日 · Nowadays, ammonia is considered the most promising solution for abating GHG emission in large-bore internal combustion engines for marine transportation and power generation sector (Kurien and Mittal, 2022), where the low energy density characteristic of the current battery technologies makes electric propulsion unfeasible.

2021年9月9日 · Visualising ammonia flame propagation. And earlier this year we reported on the team’s announcement of their world-first visualisation of an ammonia flame in an internal combustion engine. If you’ve ever been curious about what an …

Ammonia has a relatively low calorific value, and on top of that, characteristics like low cetane number and low flame speed makes it difficult to apply in combustion engines. Therefore, it is necessary to carry out investigations on how to improve the applicability of ammonia for combustion engines.

2023年8月30日 · Comptti et al. developed a hydrogen generation system (HGS) for ammonia–hydrogen-fueled internal combustion engines using a commercial ruthenium-based catalyst named ACTA 10010. The HGS heated by exhausted combustion gases performed well in hydrogen production, engine brake thermal efficiency …

2023年10月1日 · The application of ammonia and hydrogen in internal combustion engines (ICE) is a promising zero-carbon technology. This paper investigates ammonia combustion in ICE using hydrogen multiple-injection jet-ignition (MIJI). The experiment was conducted on a single-cylinder heavy-duty engine with a compression ratio of 17 and a cylinder bore of 123 mm.

2022年12月1日 · Recently, ammonia has been explored as a potential fuel for internal combustion engines, gas turbines and other industrial purposes. Ammonia consists of 17.6% by weight of hydrogen and is...

2024年3月15日 · In this study, combustion characteristics of an ammonia-hydrogen synergy internal combustion engine (ICE) was investigated. Stable ammonia combustion using hydrogen multiple-injection jet-ignition (MIJI) was achieved in a single-cylinder ICE with high compression ratio (17) and large cylinder bore (123 mm).
