Abstract
An internal combustion engine is furnished with a cross flow cylinder head 1 having an exhaust duct 11 which opens on a longitudinal side wall 12 and two intake ducts 10a, 10b which open on the upper cover surface 14 in a region of the cylinder head 1 on the side toward the longitudinal side wall 12. By having the intake ducts and the exhaust duct on the same longitudinal side of the internal combustion engine relative to the central vertical longitudinal plane through the internal combustion engine, the opposite longitudinal side of the internal combustion engine remains completely free for other attachments. A pair of intake valve stem openings 8a, 8b and a pair of exhaust stem valve stem openings 9a, 9b lie in parallel planes disposed at an angle to a longitudinal plane through the axis of the engine cylinder and an injection line opening 20 extends from the aforesaid opposite longitudinal side and between said planes to an injection valve mounting hole 17.
