Cylinder head for internal combustion engine and method to manufacture such cylinder head

摘要

An internal combustion engine has a cylinder (6), a block (2), and a cast cylinder head (1). Cylinder head has gas exchange channel (3) for conducting gases to and from the cylinder. Gas channel has a tube (5) passing through the cylinder head and into the gas exchange channel. The tube is sealed in a gastight manner and arranged partially outside the gas exchange channel parallel to the axis of the cylinder. An upper side of the block has threads parallel to tube that accept a head bolt (20). The head bolt extends through the tube and engages the threads formed in the block. An independent claim is included for a method for machining an internal combustion engine.
