Patent ID: 7089914

Claim:
In a method for operating an internal combustion engine ( 10 ), in which at least one fuel pump ( 22 , 32 ) delivers the fuel from a fuel tank ( 28 ) into a fuel line ( 20 , 24 , 26 , 34 ) and in which the pressure of the fuel, at least in a region ( 26 ) of the fuel line ( 20 , 24 , 26 , 34 ), is at least intermittently increased when the engine ( 10 ) is not running compared to its pressure during normal operation, further comprising the step of connecting a high-pressure region ( 20 , 24 ) and a low-pressure region ( 26 , 34 ) of the fuel line ( 20 , 24 , 26 , 34 ) to each other during the phase of increased pressure of the fuel, at least in the region ( 26 ) of the fuel line ( 20 , 24 , 26 , 34 ).
