Abstract
A hydrogen fueled reciprocating spark ignition engine includes a fuel system for providing gaseous hydrogen to the cylinders of the engine and a lean NOx trap coupled to the engine for treating the engine's exhaust. A controller determines when to purge the lean NOx trap and provides gaseous hydrogen to the lean NOx trap during purging by operating the engine fuel rich or injecting hydrogen upstream of the lean NOx trap.
