Abstract

If the world wants to achieve a point of net zero carbon emissions, nearly every machine that burns fossil fuels needs to be updated to CO2-free energy. Internal combustion engines powered by ammonia (NH3ICE) are becoming increasingly attractive for applications requiring larger power output, such as in the mining, marine and cogeneration sectors. In recent years, several companies have shown interest in NH3 as a fuel for internal combustion engines, and more and more universities are working on this topic with promising results.The experimental work is intended to advance fundamental knowledge of phenomena that occur when using ammonia as a fuel. Measurements in steady-state and transient-like conditions will enable analysis of combustion characteristics, efficiencies and assessing operational limits. CFD and 1D modelling will investigate burning velocities and design features to improve combustion and reduce anomalous/erratic behaviour during operation. Ammonia slip and nitrous oxide (N20, “laughing gas”) emissions will be quantified and the emission measurements of secondary and particulate formations will be performed.A Liebherr prototype ammonia/hydrogen engine, fully equipped with sensors, fuel injection system and open electronic control unit will be installed at the cutting-edge experimental facilities of the University of Nottingham. This will allow to fill many knowledge gaps around ammonia as a fuel for propulsion systems by understanding the formation and ageing mechanisms for secondary emissions, including the impact of lubricant emission and performance.
