Abstract

The invention relates to methods and to devices for controlling the fuel supply of an internal combustion engine (10) operated with liquefied gas as a fuel, wherein the liquefied gas is conveyed from a reservoir (14) containing the liquefied gas to a high-pressure fuel accumulator (19) by means of a low-pressure fuel pump (15) and a high-pressure fuel pump (17) arranged downstream of the low-pressure fuel pump (15), said high-pressure fuel accumulator having a flow connection to individual fuel injectors (Z1-Z4) associated with the respective cylinders (Z1-Z4) of the internal combustion engine (10), such that liquefied gas is injected directly into the combustion chambers of the cylinders (Z1-Z4) as needed. The fuel pressure (p
