This research paper investigates the use of natural gas/hydrogen blends in heavy-duty spark ignition engines to reduce environmental impacts and enhance performance. Experimental tests were conducted on a heavy-duty engine using CNG and two hydrogen blends (15% and 25% hydrogen by volume), revealing the need for ignition timing adjustments to optimize combustion and emissions. The study also proposes methodologies for on-board detection of hydrogen blending ratios to facilitate flexible fuel supply and engi
