A respective fuel injector is provided for each cylinder in a multiple cylinder internal combustion engine. Each fuel injector is located in a respective cylinder head. There are a plurality of fuel passages for each cylinder head. Each fuel passage into the cylinder head is in two sections. One section extends from the space for receiving the fuel injector diagonally with respect to the longitudinal direction of the engine and opens on the transverse surface of the cylinder head and is sealed there. Another passage section extends at an angle to the first passage section and then intersects the lateral side surface of the cylinder head. The two passage sections each comprise a bore in the cylinder head. A wall inside the cylinder head extends between and separates two spaces for receiving inlet valves to the injector and two spaces for receiving exhaust valves from the injector. That wall extends on one side along an air intake port into the cylinder head. On the other side of the wall is a cooling channel which separates the wall from the spaces for the exhaust valve. The wall extends diagonally to the longitudinal direction of the engine, and lines between each of the pairs of valves are essentially diagonal in the same direction as the wall.
