摘要： An internal combustion engine includes: plural cylinders, a first exhaust gas turbocharger having a high-pressure turbine and a high-pressure compressor, a second exhaust gas turbocharger having a low-pressure turbine and a low-pressure compressor, and an SCR catalytic converter positioned between the high-pressure turbine and the low-pressure turbine, via which exhaust gas leaving the high-pressure turbine is conducted upstream of the low-pressure turbine. The low-pressure compressor is assigned a power take-in, via which the low-pressure compressor can be driven when as a consequence of a relatively large exhaust gas temperature drop at the SCR catalytic converter via the low-pressure turbine an adequate amount of energy required to supply the cylinders of the internal combustion engine with a desired quantity of charge air can no longer be provided.

摘要： Method for operating an internal combustion engine which has a gas combustion system and an exhaust gas post-treatment system. Exhaust gas that leaves the gas combustion system is directed to at least one CH4 oxidation catalytic converter of the exhaust gas post-treatment system. The CH4/NO2 mole ratio in the exhaust gas is set in a defined fashion by at least one gas-combustion-system-side and/or exhaust-gas-post-treatment-system-side measure upstream of at least one CH4 oxidation catalytic converter.

摘要： An exhaust gas post treatment system for an internal combustion engine, in particular a heavy fuel oil-powered engine, including an SCR catalyst, using ammonia as a reducing agent for the denitration of the exhaust gas, and a device positioned upstream of the SCR catalyst by which ammonia or an ammonia precursor substance, which is converted to ammonia, introduced upstream of the SCR catalyst. Downstream of the SCR catalyst an exhaust gas scrubber is positioned, by which excess ammonia, contained in the exhaust gas leaving the SCR catalyst, together with sulfur oxides, can be scrubbed out of the exhaust gas forming ammonium salts while maintaining a pH value of approximately 6. For the control thereof, a bypass around the SCR catalyst can be provided as a westgate, or comprising an additional SCR catalyst.
