Abstract
The invention relates to an internal combustion engine (1) with a crankcase (3) and a cylinder head (4) having exhaust ports (9) feeding into an exhaust manifold (10) for exhaust gas from the combustion chambers (5) of the internal combustion engine (1). Provision is hereby made for the cylinder head (4) to include at least one region of a heating channel (12) which is different from the exhaust ports (9) and the exhaust manifold (10) and has an inlet side (14) branching from one of the exhaust ports (9) or the exhaust manifold (10), and which is flowed through by an exhaust mass flow that is adjustable by an actuator (13). The invention further relates to a method for operating an internal combustion engine (1).

-10. (canceled)
An internal combustion engine, comprising:
- a crankcase;
- a cylinder head having exhaust ports feeding into an exhaust manifold for exhaust gas from combustion chambers of the internal combustion engine, wherein the cylinder head includes at least a region of a heating channel which is different from the exhaust ports and the exhaust manifold, said heating channel having an inlet side branching from one of the exhaust ports or the exhaust manifold;
- and
- an actuator configured to adjust an exhaust gas mass flow flowing through the heating channel.
A method for operating an internal combustion engine, comprising:
- configuring exhaust ports of a cylinder head to feed into an exhaust manifold for exhaust gas from combustion chambers of the internal combustion engine;
- providing a heating channel different from the exhaust ports and the exhaust manifold such that at least a region of the heating channel is formed by the cylinder head;
- configuring the heating channel with an inlet side which branches from one of the exhaust ports or the exhaust manifold;
- and
- adjusting an exhaust gas mass flow flowing through the heating channel by an actuator.
