Abstract

A system and method for securing fuel injectors in an internal combustion engine includes a retainer for securing adjacent fuel injectors to a cylinder head. The retainer includes a central portion with a hole for receiving a fastener securing the retainer to the cylinder head, and a pair of symmetrical crescent-shaped forks forming a U-shaped opening with The retainer is facilitated in lateral sliding engagement with diametrically opposed flat portions on a corresponding fuel injector. Each clamping yoke includes an arcuate flange that engages a corresponding shoulder on the fuel injector to provide an axial clamping force to the fuel injector. The distance between the distal end of one prong and the semicircular base on the opposing prong is selected to allow the retainer to slide laterally out of one of the adjacent fuel injectors without rotating or removing the other fuel injector injectors to facilitate servicing of individual fuel injectors.

Description

technical field [0001] The present invention relates to systems and methods for positioning and securing fuel injectors in internal combustion engines. Background technique [0002] Various types of clamping devices or clamps have been developed in internal combustion engines for securing fuel injectors in corresponding cylinders of the engine. The holder also provides angular orientation of each fuel injector within the cylinder to properly position the injection pattern of the fuel injectors relative to the piston and intake / exhaust ports. A fuel injector holder should meet various requirements depending on the particular application, such as providing sufficient force to seal the fuel injector against combustion pressure, and providing axial force without significant flexing or torsion. Additionally, it is desirable to minimize the number of retainers and associated fasteners to reduce parts count, engine weight, and cylinder head complexity, and to simplify initial asse...
