FIELD: engines and pumps.
SUBSTANCE: direct injection fuel rail is proposed, which provides the possibility of guaranteed and smooth electroplating on the inner surfaces of the rail casing and the inlet, which is also provided with a throttling element and which has excellent mechanical properties. Direct injection fuel rail comprises steel ramp body 4, an inlet part integral with first end 5 of ramp body 4 or separately from said end and comprising communication path 7 communicating with the fuel rail channel, many nozzle holders communicating with the fuel channel. Stainless steel throttling element 1 is made separately from body 4 of the ramp and is firmly fixed in the communication path of the inlet part by means of screwing, on the outer circumference of one of the ends of throttling element 1 there is outer annular protrusion 15, which serves as a screw stop.
EFFECT: invention can be used in fuel injection systems of internal combustion engines (ICE).
