Internal combustion engine

An internal combustion engine comprising:

• a crankcase,
• a cylinder head,
• wherein the cylinder head and the crankcase delimit at least one cylinder in which a translationally moving piston is arranged,
• a water injection device for injecting water into the at least one cylinder, and
• a crankcase ventilation device which is fluidically connected to the crankcase,
• wherein a blow-by mixture containing injection water can flow through the crankcase ventilation device,
• wherein the crankcase ventilation device has an activated charcoal filter through which the blow-by mixture containing the injection water can flow,
• wherein the water injection device has a water injector which is arranged in an intake tract that is configured to be fluidically connected to the cylinder,
• wherein the crankcase ventilation device is fluidically connected to the intake tract such that the gases of the blow-by mixture are conducted into the intake tract,
• wherein the crankcase ventilation device includes an inlet through which the blow-by mixture is delivered to the activated charcoal filter for filtering, a first outlet through which filtered gases of the blow-by mixture are delivered to the intake tract, and a second outlet through which filtered injection water is delivered to the water injection device.
