Effect of ammonia addition on combustion and emissions performance of a hydrogen engine at part load and stoichiometric conditions

International journal of hydrogen energy, 2021
The development of alternative fuels is important in the fight against climate change. Both hydrogen and ammonia are renewable energy sources and are carbon-free combustible fuels.

Numerical study of the effect of injection timing on the knock combustion in a direct-injection hydrogen engine

, 2020
Knock combustion is one of the main barriers to the use of hydrogen as an engine fuel. This paper focuses on the effect of injection timing on knock characteristics in a direct-injection hydrogen engine by numerical simulation.

Simulation and experimental study of the NOx reduction by unburned H2 in TWC for a hydrogen engine

International journal of hydrogen energy, 2020
The unburned H2 can be used to reduce NO emission in conventional TWC (three-way catalyst) for a hydrogen internal combustion engine when it works at equivalence ratio marginally higher than the stoichiometric ratio.

The Hydrogen Engine

Nature, 1954
IT has always been stated by others that it is necessary to use weak mixtures with air when hydrogen is used as a fuel for Otto-cycle engines. Thus Ricardo1 reported that “if an attempt were made to run with a rich hydrogen–air mixture violent pre-ignition occurred, accompanied by firing back in the carburettor, which rendered further running ...

Engineering spherical nanostructures through hydrogen bonds

Chemical Communications, 2009
Chromophoric acetylenic scaffolds bearing complementary uracyl and 2,6-di(acetylamino)pyridyl moieties undergo supramolecular recognition and generate uniform nanoparticles, as observed by UV-Vis, AFM and TEM measurements.
