Abstract

A fuel injection apparatus includes a shared pressure reservoir, an injector, a pressure intensifier, and valves for controlling the injection process and the pressure intensification. A modular design is produced by means of a pressure intensifier module, and a valve module, thereby reducing costs and increases flexibility in the manufacture of fuel injection apparatuses.
