Abstract
An internal combustion engine having an engine block, a cylinder head, a crankcase and at least one cylinder includes a crankcase ventilation line connected to at least one intake line. The crankcase ventilation line is arranged at least predominantly within the internal combustion engine, in particular within the engine block and/or within the cylinder head, thereby greatly minimizing or eliminating the potential for release of crankcase gas to the environment.
