The thesis is focusing on the potential roles and applications of NH3 in transportation area, where ammonia is applied i) as a hydrogen carrier involved in a catalytic reforming process tor H2 production, ii) in its reformed form i.e. H2-NH3 mixture for improved NH3 combustion in CI engines (as a carbon-free energy carrier), and iii) as a reductant in engine emission abatement under the incorporation of the NH3 reforming mechanism and catalytic aftertreatment systems. To implement the above studies, a prototype reformer system and a catalytic reaction mechanism were designed and proved capable of producing Hz-contended reformate. The reformed NH3 i.e. H2-NH3 mixture was later applied in diesel operation and demonstrated successful engine decarbonisation. With a further incorporation of a Silver/Alumina catalyst in the engine exhaust system, the reformate was revealed as viable reductant for low temperature NOx abatement. Therefore, a combination of the studied systems show a great potential in simultaneous diesel engine emissions reductions, which include CO2, CO, HC, PM and NOx.
