Abstract: In a cylinder head for a multi-cylinder internal combustion engine, wherein the cylinder head includes between its bottom top and side walls a cooling water space through which intake and exhaust passages extend and also columns with bores for receiving cylinder head mounting bolts and well structures for receiving spark plugs or fuel injectors and the bottom wall delineates at its lower side a combustion chamber for each cylinder, wall structures are cast onto the top side of the cylinder head bottom wall and extend in the circumferential area of each combustion chamber in transverse and longitudinal directions between adjacent columns with which they are integrally formed and at least the transverse wall structures extend upwardly and join the top wall and the intake and exhaust passages extend through, and are joined to, the longitudinal wall structures.

Abstract: An emergency shut-off device for an air-compressing internal combustion engine is provided in the filter head of the engine fuel filter for the purpose of shutting off the fuel supply for shutting down the engine when the engine cannot be turned off by the ignition key.
