An internal combustion engine has a working cylinder with two intake valves and two exhaust valves assigned thereto. A first camshaft and a second camshaft each actuate a respective one of the intake valves and a respective one of the exhaust valves. The first camshaft is a variable camshaft with an adjuster for adjusting valve control times and includes an outer shaft, which is a hollow shaft, and an inner shaft, which is disposed within the outer shaft. The outer shaft as well as the inner shaft are rotatable by the adjuster and are rotatable relative to one another by the adjuster such that relative positions of given cams controlling given ones of the intake and exhaust valves are changeable. The second camshaft is driven by a crankshaft of the internal combustion engine and is configured as a fixed camshaft. |
