  "textContent": "A sparked reciprocating four-stroke internal combustion hydrogen-fueled engine having a casing, a rotatable crankshaft, a cylinder inside the casing, a piston inside the cylinder to movably reciprocate along an axis between top and bottom dead center positions (TDC, BDC) and operatively connected to the crankshaft such that the piston imparts a rotational movement to the crankshaft, a combustion chamber within the cylinder between the engine casing and piston head opposite the crankshaft, intake and exhaust valves, hydrogen and water injectors; a spark or glow plug, and an engine control unit to control timing and quantity of hydrogen and water injections by injecting into the combustion chamber first, second, and third quantities of hydrogen at first, second, and third timings, respectively, from 20° before TDC during compression stroke to 20° after TDC, from 110° to 90° before TDC during compression stroke and from 180° to 100° before TDC during compression stroke.",
