An internal combustion engine having: at least one piston-cylinder unit, a turbocharger having an exhaust gas turbine, a catalytic converter connected between the at least one piston-cylinder unit and the exhaust gas turbine, and a control device, wherein the control device is designed to control a fluid-delivery device such that, when the internal combustion engine is in a state in which no combustion and/or ignition takes place in the at least one piston-cylinder unit, the fluid-delivery device delivers fuel-air mixture through the catalytic converter.

Internal combustion engine

Embodiments relate to an exhaust gas after-treatment device with an exhaust line having an inlet for discharging the exhaust gas and a thermal reactor, which is arranged in the exhaust line and has a first, thermal reaction zone for the exhaust gas flow, where a mixing device is provided for admixing a reducing agent to the exhaust gas flow in the exhaust line, which is arranged between the inlet and the thermal reactor and where the thermal reactor has at least one second reaction zone for a catalytic reaction in the exhaust gas flow with the involvement of the reducing agent.

Exhaust gas after treatment device

An exhaust gas aftertreatment apparatus for an internal combustion engine, in particular a stationary internal combustion engine having at least one catalyst unit for exhaust gases, which is arranged downstream of the internal combustion engine. Exhaust gases from the internal combustion engine can be taken past the at least one catalyst unit by way of a bypass conduit, and the at least one catalyst unit and the bypass conduit are arranged in a common housing. The housing has at least two separate feed conduits for untreated exhaust gas and at least one outlet conduit for exhaust gas treated by the at least one catalyst unit.

Exhaust gas aftertreatment apparatus

An internal combustion engine is provided, which includes at least one combustion chamber, and a turbocharger with an exhaust gas turbine and an exhaust gas after-treatment device. The exhaust gas after-treatment device has a first catalytic converter arranged aerodynamically between the at least one combustion chamber and the exhaust gas turbine. A second catalytic converter is arranged aerodynamically between the first catalytic converter and the exhaust gas turbine, and at least one partial oxidation chamber is arranged aerodynamically between the first catalytic converter and the second catalytic converter. Also provided is a method for reducing exhaust gas emissions of an internal combustion engine.

Internal combustion engine for reducing exhaust gas 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

A method of starting up a thermoreactor arranged in an exhaust gas flow of an internal combustion engine includes igniting combustion gas by spark ignition in at least one cylinder of the internal combustion engine. The exhaust gas resulting from the combustion of the combustion gas is fed at least partially to the thermoreactor as an exhaust gas flow. The temperature of the exhaust gas resulting from combustion of the combustion gas is increased by the moment in time of the spark ignition being selected later in comparison with a present moment in time.

Method of starting up a thermoreactor

A method of exhaust gas aftertreatment of an exhaust gas of an internal combustion engine includes pre-treating the exhaust gas pre-treated by using a thermoreactor to catalytically oxidize the exhaust gas. Preferably, the exhaust gas is catalytically oxidized in the thermoreactor.

Method of exhaust gas aftertreatment

A method of regenerating an oxidation device () of an internal combustion engine (), in particular a stationary internal combustion engine, wherein the oxidation device () is connected downstream of the internal combustion engine () and wherein a mixture of combustion gas and exhaust gas can be fed to the oxidation device () to increase a temperature in the oxidation device () and wherein exhaust gas can be passed around the oxidation device () by way of a bypass conduit (), wherein the amount of exhaust gas passed around the oxidation device () by way of the bypass conduit () is controlled in open-loop or closed-loop control mode in dependence on an ascertained exhaust gas temperature downstream of the oxidation device ().

Method of operating an internal combustion engine

A mixing device having a chamber is provided. The chamber includes an inlet, a main body, and a flow axis. The main body is configured for containing a fluid circulating generally along the flow axis. The inlet is configured to receive at least one fluid stream and is oriented in a flow plane generally perpendicular to the flow axis. A plurality of mixing channels that each receive portions of the fluid stream from the inlet are provided. The plurality of mixing channels are each oriented along the flow plane and have unequal distinct lengths configured to release the portions of the fluid stream into the chamber at discrete time intervals.
