Abstract

In a method for determining the rail pressure in a common rail system of an internal combustion engine, at least one measurement variable is determined which is a measure for the angular velocity of a crankshaft movement of the internal combustion engine, and the rail pressure is determined from said measurement variable or from a variable derived from the measurement variable. Furthermore disclosed are methods that are based thereon for controlling an injection quantity and for controlling a rail pressure, and a corresponding common rail injection system.
