Abstract (en)
Fuel injector (10) for direct injection in an internal combustion engine, the fuel injector (10) being designed to be inserted into a mounting bore (14) of a cylinder head (12) which opens into a combustion chamber (16), said fuel injector (10) having an injector body (18) which ends with a tip portion (20) provided with a nozzle (22), characterized by said tip portion (20) being provided with at least one tip seal (38) comprising a ring shaped body formed of metallic wire mesh, said tip seal (38) being able to close the annular gap between the tip portion (20) and the mounting bore wall (40) in view to dissipate thermal energy from the tip portion (20) to the cylinder head (12), and said tip seal (38) being elastically flexible in order to allow radial compression of the tip seal (38) during mounting and dismounting operations of the fuel injector (10) in the mounting bore (14).
