An Experimental Study on the Effects of Pre-Chamber Geometry on the Combustion Characteristics of Ammonia/Air Mixtures Using Turbulent Jet-Post Spark Ignition Strategy

Energies
As a carbon-free fuel, ammonia faces challenges in engine applications due to its low flame propagation speed and high ignition energy. The pre-chamber turbulent jet-post spark ignition strategy (TJ-PSI) has been proven effective in accelerating the ...

Nutritional Status Assessment During the Phase IIA and Phase III Lunar/Mars Life Support Test Project [PDF]

, 2000
Nutrition is a critical concern for extended-duration space missions (Smith and Lane, 1999). Loss of body weight is a primary consequence of altered nutrition, and is frequently observed during space flight (Smith and Lane; 1999).

Effect of structural parameters of active pre-chamber on ammonia/hydrogen premixed combustion process: A numerical investigation

Case Studies in Thermal Engineering
The development of zero-carbon fuels is of great significance for reducing carbon emissions. Using an ammonia/hydrogen mixture as fuel, the combustion in engine through an active pre-chamber has a good effect on reducing carbon emissions.
