1. A method of operating a gaseous fuel engine system comprising:
combusting a mixture containing a gaseous hydrogen fuel and air in a cylinder of an engine in the gaseous fuel engine system;
varying an at least one operating parameter of the engine to which a crown surface temperature of a piston within the cylinder is responsive;
populating a temperature model based on a value of the varied at least one operating parameter;
operating an oil spray apparatus to spray oil onto the piston based on the populated temperature model;
maintaining the crown surface temperature of the piston between a high temperature limit and a pre-ignition mitigation temperature limit based on the operating of the oil spray apparatus; and
wherein the varying an at least one operating parameter includes varying a ratio of the gaseous hydrogen fuel to a hydrocarbon fuel in the mixture containing the gaseous hydrogen fuel and air.
