Abstract
The invention relates to a piston internal combustion engine comprising upper camshafts ( ) for actuating gas exchange valves, whereby respectively adjacent lying bearings of the induction-side camshaft ( ) and the exhaust-side camshaft ( ) are provided with a covering element ( ) scaling both bearings. The inventive engine is also provided with direct fuel injection by means of a respective injector device ( ) 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 ( ) and a cross brace ( ) is fixed to the cylinder head ( ) in a deflection-resistant manner, overlapping with at least one injector device ( ). The cross brace is connected to tightening elements ( ) enabling the injector devices ( ) to be sealingly tightened in relation to the cross brace ( ). The cross brace ( ) is connected to least two neighbouring bearing-covering elements ( ).
