Procedure to operate a fuel system of an internal combustion engine
First Claim
1. Procedure to operate a fuel system (10) of an internal combustion engine (12), in which the fuel is compressed by a fuel pump (20) and travels by way of at least one fuel injection device (24) into at least one combustion chamber (36) of the internal combustion engine (12) is thereby characterized;
- in that at least periodically during a phase immediately when starting or just after starting the internal combustion engine (12), the fuel pump (20) is actuated corresponding to an increased set point pressure (pincr); and
in that an increase of the set point pressure (pincr) is, however, blocked, if at least one blocking condition is met (B2=false).

Abstract
In the operation of a fuel system (10) of an internal combustion engine (12), the fuel is compressed by a fuel pump (20) and travels by way of at least one fuel injection device (24) into at least one combustion chamber (36) of the internal combustion engine (12). It is proposed that at least periodically during a phase immediately when starting or just after starting the internal combustion engine (12), the fuel pump (20) is actuated corresponding to an increased set point pressure. An increase in the set point pressure, however, is blocked if at least one blocking condition is met.
