Abstract
A controller for an internal combustion engine of a generator set operates the engine at a first, low load condition at a lean air/fuel ratio using hydrogen fuel, and at a second, high load condition at a richer air/fuel ratio using gaseous fuel. The controller transitions from the first condition to the second condition by adding gaseous fuel to achieve the richer air/fuel ratio during a transient event.
