Abstract
To provide an injection system for an internal combustion engine operating on self-igniting liquefied gas as a fuel, and to minimize cavitation and related problems of fuel delivery as well as wear, the fuel tank is configured as a low-pressure storage tank which is connected to a pressure control unit that includes a fuel pumping unit for drawing fuel from the storage tank and delivering the fuel to the suction line of the fuel delivery device and a pressure release line which branches off the suction line and leads back to the storage tank, the pressure release line including a release valve for maintaining a constant interior pressure in the suction line above the vapor pressure of the liquefied gas. The injection system is configured as a leakage-free system.
