The invention relates to a piston internal combustion engine comprising upper camshafts (2, 3) for actuating gas exchange valves, whereby respectively adjacent lying bearings of the induction-side camshaft (2) and the exhaust-side camshaft (3) are provided with a covering element (5) scaling both bearings The inventive engine is also provided with direct fuel injection by means of a respective injector device (7) which has a nozzle part and which is associated with a cylinder (I, II, III, IV). The nozzle part is sealingly inserted into an opening in the cylinder head (1) and a cross brace (8) is fixed to the cylinder head (1) in a deflection-resistant manner, overlapping with at least one injector device (7). The cross brace is connected to tightening elements (11) enabling the injector devices (7) to be sealingly tightened in relation to the cross brace (8). The cross brace (8) is connected to least two neighbouring bearing-covering elements (5).
A piston-type internal combustion engine, provided with overhead camshafts (2, 3) for actuating the cylinder valves, wherein respectively side-by-side arranged bearings of the intake-side camshaft (2) and the discharge-side camshaft (3) have a bearing cover element (5) that closes off both bearings, further provided with direct fuel injection through a respective injection device (7) assigned to each cylinder (I, II, III, IV) and provided with a nozzle unit, which is inserted so as to be sealed into an opening in the cylinder head (1), further provided with a crossbar (8) that is rigidly fastened to the cylinder head (1) and spans at least one injection device (7), which crossbar is connected to tightening means (11) for a sealed tightening of the injection devices (7) relative to the crossbar (8), and wherein the crossbar (8) is connected to at least two neighboring bearing cover elements (5).
