    Abstract: An internal combustion engine (10) is an operating gas circulation type internal combustion engine that uses argon as the operating gas, for example, and includes a hydrogen and oxygen supply portion (40,50), an argon supply amount regulating portion (70), and an electric control unit (80). The electric control unit determines the amount of hydrogen and oxygen to be supplied to a combustion chamber (21) based on a required torque which is the torque required of the internal combustion engine, and supplies the determined amounts of hydrogen and oxygen to the combustion chamber using the hydrogen supply portion and the oxygen supply portion. Further, the electric control unit determines an amount of operating gas to be supplied to the combustion chamber according to the required torque, and controls the argon supply amount regulating portion such that the determined amount of operating gas is supplied to the combustion chamber.

    Abstract: Described here are systems and methods for treating fuel injected exhaust streams. In general, the systems comprise a fuel injector, a pre-combustor, and a fuel combustor. The methods described herein include methods for regenerating a NO x trap or a DPF, and methods for generating a substantially uniform fuel air mixture at a fuel combustor inlet, or a substantially uniform temperature at a fuel combustor outlet. The methods of regenerating a NO x trap typically comprise the steps of injecting fuel into an exhaust stream, passing the stream through a pre-combustor, operating the pre-combustor to at least partially combust the injected fuel, reacting the fuel and exhaust stream mixture within a fuel combustor to generate a reducing gas mixture, and introducing the reducing gas mixture into a NO x trap, whereby the NO x trap is regenerated. Similar methods for regenerating a diesel particulate filter are also described. Control strategies are also provided.
