Abstract
The disclosure relates to a method for operating an internal combustion engine comprising at least two cylinders and a system for fuel injection, in which the fuel is withdrawn from a primary tank and supplied to at least one rail in a form significantly compressed compared with atmospheric pressure, and a plurality of cylinders draw the gaseous fuel from a rail used collectively, wherein, during operation of the internal combustion engine, the pressure target value of the gaseous fuel stored in the rail is controlled to or otherwise held at a constant value or a variable target value, which changes only in a small range B, irrespective of the engine operating point.
