1. A method of operating a gaseous fuel engine comprising:
spark-igniting a mixture containing gaseous hydrogen fuel and air at a spark gap in a gaseous fuel engine;
propagating combustion gases of the spark-ignited mixture outwardly from the spark gap in a combustion cylinder in the gaseous fuel engine;
limiting a flame area of combusting gaseous hydrogen fuel and air in the combustion cylinder by way of contacting some of the propagating combustion gases to a cone surface of a piston; and
urging the piston in the gaseous fuel engine toward a bottom-dead-center position based on an increase in pressure in the combustion cylinder caused by combustion of the gaseous hydrogen fuel and air.
