Internal combustion engine with exhaust-gas aftertreatment system and method for operating an internal combustion engine of said type

An internal combustion engine comprising:

• two cylinders, wherein each cylinder has an outlet opening for discharge of exhaust gases out of each cylinder through an exhaust system, and wherein each outlet opening is adjoined by an exhaust line;
• an exhaust-gas aftertreatment system arranged in the exhaust system;
• an electric heating device having a heating element arranged in the exhaust system upstream of the exhaust-gas aftertreatment system;
• and
• an adjustment device coupled to a rotational shaft extending through opposing sides of a frame, wherein the adjustment device adjusts the electric heating device from an active position where the electric heating device at least partially blocks the exhaust system to generate a flow resistance for the exhaust gas in the exhaust system, into a passive position where the electric heating device blocks the exhaust system to a lesser extent to reduce the flow resistance for the exhaust gas in the exhaust system, wherein the adjustment takes place independently, and wherein the rotational shaft rotates about an axis longitudinally extending through the rotational shaft during adjustment of the electric heating device.
