Abstract: A method for operating an internal combustion engine includes first operating the internal combustion engine in a first operating state and setting a second operating state, different from the first operating state, by advancing the exhaust camshaft relative to the crankshaft by a value in comparison with the first operating state. The exhaust valve is actuated by the exhaust cam and a decompression lift of the exhaust camshaft, whereupon, in the second operating state, the cylinder assumes a function of a decompression brake by compressing a first cylinder charge in the cylinder within a respective operating cycle of the internal combustion engine and then decompressing it by a decompression travel of the exhaust valve in a region of a charge exchange top dead center. In the second operating state, the intake camshaft is retarded relative to the crankshaft by a value.
