Abstract

Système d'injection de carburant (100) comportant un premier accumulateur haute-pression (1), un second accumulateur haute-pression (2) et une pièce de liaison (3). Le premier accumulateur (1) a une première chambre haute-pression et le second accumulateur (2), une seconde chambre haute-pression. Le premier accumulateur (1) a un premier branchement (la) pour un premier injecteur et le second accumulateur (2) un second branchement (2a), pour un second injecteur . La pièce de liaison (3) relie le premier accumulateur (1) au second accumulateur (2). La pièce de liaison (3) a un canal de liaison qui relie les deux chambres.Fuel injection system (100) comprising a first high-pressure accumulator (1), a second high-pressure accumulator (2) and a connecting piece (3). The first accumulator (1) has a first high pressure chamber and the second accumulator (2), a second high pressure chamber. The first accumulator (1) has a first connection (la) for a first injector and the second accumulator (2) has a second connection (2a), for a second injector. The connecting piece (3) connects the first accumulator (1) to the second accumulator (2). The connecting piece (3) has a connecting channel which connects the two chambers.
