INTERNAL COMBUSTION ENGINE WITH CYLINDER HEAD, AND METHOD FOR PRODUCING A CYLINDER HEAD OF AN INTERNAL COMBUSTION ENGINE OF SAID TYPE

摘要

The application relates to internal combustion engines, cylinder heads, exhaust passages, and shapes and configurations of the exhaust passages. The exhaust passage may have cross-sectional shapes formed by two limbs. The cross-sectional shape of the exhaust passage may change as the passage extends. The exhaust passage may also merge with other exhaust passage. The exhaust passage may be part of a cylinder head or an exhaust manifold.
