Abstract

A method and a device for controlling an internal combustion engine having a high-pressure injection, and in particular, for controlling an internal combustion engine having a common rail system. The fuel is delivered by at least one pump from a low-pressure area into a high-pressure area. The fuel pressure prevailing in the high-pressure area is detected by a pressure sensor and is regulated by a pressure-regulation means. Given a defect in the area of the pressure regulation, the fuel pressure is controlled by influencing the flow of fuel in the low-pressure area.
