Beschreibung
Zusammenfassung:	Invention relates to a common rail fuel injection system (10) for a multicylinder internal combustion piston engine (11), comprising at least two fuel injectors (14), wherein each one of the injectors (14) is provided with a first accumulator space (16), a fuel supply line (18) arranged in flow communication with each one of the first accumulator spaces (16). Each one of the high-pressure pump units (30) comprises a high-pressure pump (32) and a second accumulator space (34) and the second accumulator spaces (34) being in flow connection with each other, forming an array (38) of second accumulator spaces (34) such that the first one of the second accumulator spaces (34) is at a first end (38.1) of the array (38) and a last one of the second accumulator spaces (34) is at a second end (38.2) of the array (38), and the array (38) of second accumulator spaces (34) is in flow communication with the fuel supply line (18).
