Decarbonisation of heavy-duty diesel engines using hydrogen fuel: a review of the potential impact on NOx emissions

“…87 Achieving lower NO x emissions using after-treatment technologies rather than altering engine design, is reported widely. 80,93 JCB reported a 98% reduction in engine-out NO x emissions and no reduction in performance for hydrogen fuel, as compared against a pure diesel comparison with after-treatment technology system. 70 It is therefore possible that latest engineering innovation has overcome some of the compromises between engine performance and tailpipe emissions.…”
