CONSTRUCTIONAL UNIT AND FRESH AIR SYSTEM

摘要

The invention relates to a pre-assembled constructional unit (1) of a fresh air system (2) for an internal combustion engine, especially of a motor vehicle. Said constructional unit comprises an electrical unit (3) having respective coils (5) for a plurality of cylinders of the internal combustion engine for actuating a fuel injection valve, said electrical unit having an electric wiring (6) for actuating the coils (5), a plurality of parallel insertion openings (10) that extend coaxially through the coils (5), and a plastic element (9) that is injection-molded on the coils (5) and the wiring (6). The constructional unit further comprises a fuel unit (4) having respective tubular connecting pieces (12) for every coil (5) for receiving a respective injection valve and a distributor housing (13) that contains a fuel distributing compartment (14) on which the parallel connecting pieces (12) are arranged and that has connecting openings (15) which interconnect the distributing compartment (14) to the interior of the connecting pieces (12) so as to communicate therewith, the fuel unit (4) and the electrical unit (3) being mounted to each other in such a manner that the connecting pieces (12) are coaxially inserted in the insertion openings (10).
