Abstract (en)
[origin: DE19939428A1] Fuel is injected by means of a high-pressure pump (2) and a pressure accumulator chamber (6) that produces and accumulates a first system pressure. Said system pressure is not used for injection. Instead, a higher injection pressure is produced during injection by means of a pressure multiplicator (9). Said pressure can be reduced to shape the course of the injection. The inventive method and device facilitates an improved dosage of the fuel injected and an improved establishment of faster switching times.
