Protection mean for the nozzle of an injector

A protection mean (40) for the nozzle (24) of a multi-port fuel injector (12) is axially (X) arranged in the mounting bore (16) of the cylinder head of a direct injection combustion engine (10). The bore (16) opens in a combustion chamber (18), the tip point (22) of the injector (12) being its nozzle (24) set to deliver pressurized fuel. The protection mean (40) axially extends beyond the nozzle (24) to prevent said nozzle (24) from being in direct contact with lateral gas motions (A) created by pressure differences occurring inside the combustion chamber (16).
