Method for independent recognition and reaction to different fuel properties, in particular cold properties of paraffinic liquids, in particular paraffinic fuels of an associated fuel supply system

摘要

The invention relates to a method for determining different properties of paraffinic liquids, in particular cold properties of liquid fuels (F) in a fuel supply system (10), the outside temperature (TA) being measured by an outside temperature sensor outside and inside the operation of the fuel supply system (10). pressure and temperature values (p20, T18) near the fuel supply system (10) and, during operation, downstream of a fuel filter (16) which is arranged between a fuel feed pump (14) and an injection pump (32) of the fuel supply system (10) ) by pressure and temperature sensors (20, 18) arranged in a fuel line (12) or in components after the fuel filter (16). Procedures are proposed which enable paraffinic fuels with different low-temperature properties to be detected , whereby by the created V experience shows that the fuel supply system (10) is used to automatically react to the different cold properties to ensure the function of the fuel supply system (10).
