Claim 10:
11. The method of claim 9, wherein the engine is provided with
a compressor configured to pressurize the gaseous stream of second reactant supplied to the engine,
a turbine configured to drive the compressor, and configured to be propelled by the exhaust stream,
a catalytic afterburner in the exhaust stream intermediate the engine and the turbine, the afterburner being configured to react additional reactants in the exhaust stream, and
an injector configured to inject a third reactant in the exhaust stream for reaction by the afterburner;
wherein in the step of controlling, the flow rate of the gaseous stream of second reactant is controlled by controlling the quantity of the third reactant injected into the exhaust stream by the injector.
