Abstract

In order to increase the safety of an injection system in an internal combustion engine operating on self-igniting liquefied gas as a fuel, especially after the engine has been switched off, the proposal is put forward that at least one pressurized part of the injection system be depressurized by means of a shut-down device, the latter including at least one pressure relief line which is controlled by at least one valve and opens into a tank with a low pressure level.
