    摘要： In a multi-cylinder internal combustion engine, provided with a system for variable actuation of the intake valves of the engine, the fuel injector (I) associated to each engine cylinder is surrounded by a sealing casing (57) which is part of a support body (19A-D; 70). The support body (19A-D; 70) is mounted on the engine cylinder head with the interposition of a support (50) surmounting the head and defining the seat in which the camshaft (11) is received and it defines a sealing peripheral edge cooperating with a sealing cover (58) which is mounted on the cylinder head. The cover (58) has a general base plane sealingly mounted on the cylinder head or on the support (50). The sealing peripheral edge of each sealing casing (57) is arranged in a parallel plane and raised with respect to the general base plane of the cover (58).

    摘要： In a multi-cylinder internal combustion engine, provided with a system for variable actuation of the intake valves of the engine, the hydraulic means and the solenoid valves for the variable actuation of the intake valves of the various cylinders are carried by independent support bodies (19A-D), part of independent sub-units (20A-D). The unit for variable actuation of the intake valves, constituted by the aforementioned sub-units (20A-D) is closed at the upper part by a cover (58) with the interposition of a sealing gasket (60). The sealing gasket has a main portion extending in a general plane for supporting the cover and respective portions (61A-D) associated to said sub-units (20A-D) projecting from said general plane, in positions arranged longitudinally adjacent to each other on one side of the cylinder head. Each of said portions (61A-D) has a three-dimensional development, with two lateral parts (62) contained in two planes substantially parallel to each other and orthogonal to said general plane and a central part (63) contained in a parallel plane and spaced from said base plane. The fuel injector associated to each engine cylinder is surrounded by a sealing casing which is part of a support body of the variable actuation means of the intake valves and which defines a sealing peripheral edge cooperating with the abovementioned sealing cover. The sealing peripheral edge of each injector casing is contained in a parallel plane and raised with respect to the general base plane of the abovementioned cover.
