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 ( ).

An electromagnetic actuator includes an electromagnet composed of a yoke provided with a pole face and a solenoid which is carried by the yoke and which is energizable with electric current for generating electromagnetic forces. An armature coupled to a setting member is movable into engagement with and away from the pole face of the yoke. A resetting spring is connected to the armature for opposing movements of the armature toward the pole face. The yoke and/or the armature is at least in part elastically deformable toward the armature and the yoke, respectively.
