Method for determining rail pressure for controlling internal-combustion engine, involves seizing fuel pressure and comparing to desired value using controller

摘要

The method involves seizing the fuel pressure and comparing to a desired value (S) using a controller (100) on the basis of the comparison of a control factor (A). A rail break pressure (P) is determined on the basis of the size, which characterizes the electrical size of the controller. The rail break pressure is determined on the basis of the current (I) that flows through the controller. An independent claim is also included for a device for controlling the internal-combustion engine.
