An internal combustion engine (), with an engine regulating device () and an exhaust gas aftertreatment device () with an SCR catalytic converter () for the reduction of at least one NOcomponent, and with a catalytic converter regulating device (), wherein the engine regulating device () is prescribed a target value for an NOmean value of the NOcomponent of the exhaust gases, which mean value results at an outlet point () of the exhaust gas aftertreatment device () in relation to a predefinable time period, and the engine regulating device () is configured at least in one operating mode to continuously calculate an NOreference value for the catalytic converter regulating device () with consideration of Nocomponents which have already been emitted and the predefined target value, which reference value is selected in such a way that the predefined target value results at the outlet point of the exhaust gas aftertreatment device () at the end of the predefinable time period when the calculated NOreference value of the catalytic converter regulating device () is fed as NOsetpoint value to the regulating means.

Internal combustion engine with exhaust gas aftertreatment and control of the nitrogen oxide emissions

A catalytic converter device for a stationary internal combustion engine includes at least one bracket for mounting the catalytic converter device on a carrier, and at least one catalyst substrate which can be releasably arranged in a housing of the catalytic converter device, the catalyst substrate having a cell density of at least 50 cpsi, preferably greater than 100 cpsi.

Catalytic converter device for a stationary internal combustion engine

An internal combustion engine includes one main combustion chamber for the combustion of a first combustion mixture, one pre-combustion chamber for each respective main combustion chamber for the combustion of a second combustion mixture, a first fuel gas mixer for providing the first combustion mixture, a second fuel gas mixer for providing the second combustion mixture, an air feed line and a synthesis gas feed line, a first mixture line connected to the first fuel gas mixer and the main combustion chamber, and a second mixture line connected to the second fuel gas mixer and the pre-combustion chamber. The first fuel gas mixer is connected to the synthesis gas feed line for the admixing of synthesis gas, and an open or closed loop control device is provided for open or closed loop controlling mixing ratios of fuel, air and synthesis gas in the first combustion mixture and/or second combustion mixture.

Internal combustion engine

A method of operating an internal combustion engine-reformer installation having an internal combustion engine and a reformer, includes predetermining at least one parameter of the internal combustion engine, calculating a desired amount of fuel for the reformer on the basis of the at least one parameter, feeding the desired amount of fuel to the reformer, reforming fuel to give a synthesis gas in the reformer, and feeding the synthesis gas to the internal combustion engine. A synthesis gas pressure of the synthesis gas downstream of the reformer is measured, and the synthesis gas pressure is taken into consideration when calculating the desired amount of fuel.

Internal combustion engine-reformer installation

An internal combustion engine reformer installation comprises an internal combustion engine, a mixing device having a first feed conduit for a first substance flow and a second feed conduit for a second substance flow, wherein a mixture can be produced from the first and second substance flows in the mixing device, a reformer for reforming the mixture to afford a synthesis gas, a mixture conduit connected to the mixing device and the reformer, and a synthesis gas feed conduit connected to the reformer and the internal combustion engine. A first heat exchanger in heat-coupling relationship with the first feed conduit and a second heat exchanger in heat-coupling relationship with the second feed conduit are arranged in the synthesis gas feed conduit.
