Patent ID: 7121480

Claim:
A fuel injector for spraying fuel into a combustion chamber of an internal combustion engine, the injector comprising a body ( 5 ) for securing to the engine and a spray head ( 6 ) extending along a central axis (X) from a base ( 6 a ) connected to the body to an end ( 6 b ) that is free, said head ( 6 ) including an internal injection chamber ( 7 ), a free outside face ( 6 c , 6 d ) extending between the base and the free end, and including a plurality of injection orifices constituted by at least two groups ( 10 , 20 , 30 ) of injection orifices extending from an internal opening situated in the injection chamber ( 7 ) to an external opening situated in the outside face ( 6 d ), each of said groups ( 10 ; 20 ; 30 ) of injection orifices comprising a first orifice ( 11 ; 21 ; 31 ) and at least one second orifice ( 12 ; 22 ; 32 ), each adapted to spray a jet of fuel in a respective first and second directions (D 11 , D 21 , D 31 ; D 12 , D 22 , D 32 ), said first and second directions forming between them an acute angle (α) in such a manner that the jets from a group of orifices intercept in a so-called “bursting” zone situated at a distance from the outside face, the injector being characterized in that all of the internal openings of said plurality of orifices are situated in a common plane (P) extending substantially transversely relative to the central axis (X) of the head ( 6 ) of the injector.
