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 maintaining a constant interior pressure at a level above that of the vapor pressure of the liquefied gas, preferably at 6 to 30 bar, approximately, and further the injection system is configured as a leakage-free system.
