Embodiment Construction
[0027] figure 1 A schematic diagram of an internal combustion engine 10 is shown, the outlet 12 of which is connected to an exhaust system 20 . The internal combustion engine 10 is designed as an Alto engine, which is externally ignited by means of spark plugs 16 and has a plurality of combustion chambers 14 . The internal combustion engine 10 is preferably embodied as an internal combustion engine 10 supercharged by means of an exhaust gas turbocharger 30 , wherein the turbine 32 of the exhaust gas turbocharger 30 is downstream of the outlet 12 and upstream of a first emission-reducing exhaust gas aftertreatment component, In particular, it is arranged upstream of the particle filter 24 . The exhaust gas system 20 comprises an exhaust gas duct 22 in which a particle filter 24 is arranged in the flow direction of the exhaust gas through the exhaust gas channel 22 , an electrically heatable three-way catalytic converter 26 is arranged downstream of the particle filter 24 and f...
