Abstract
A method and an assembly for controlling the pressure in a high-pressure region of an injection system in an internal combustion engine. A set high pressure is compared to an actual high pressure in order to determine a control deviation, the control deviation representing an input variable of a controller. A high pressure pump is controlled by a solenoid valve and the angle at which the delivery of fuel by the at least one high-pressure pump is to start is used as a manipulated variable of the high-pressure closed-loop control system.
