Definitions

  • the invention relates to a fuel preheating method for internal combustion engines with heavy oil operation and a fuel system therefor, with a fuel delivery pump that draws preheated fuel from a fuel supply system, with a fuel filter connected downstream of the fuel delivery pump, and with a fuel injection system that is supplied with filtered fuel.
  • the invention has for its object to provide a fuel preheating process for internal combustion engines of the type mentioned, which makes it possible to start with pure fuel oil operation with a simple preheating device, in particular while protecting the fuel filter from impermissible pressures.
  • the fuel feed pump pumps fuel from the fuel supply system through the dirty space of the fuel filter, the fuel in the clean room of the fuel filter being heated to flowability by the fuel flowing past.
  • this can be done by shutting off the Return line from the dirty room to the fuel supply system or more simply by grading the cross-sections between the larger clean room and smaller dirty room outflows.
  • the operability of the fuel filter and the entire fuel system is thus established without additional heat supply devices being required in addition to a known preheating element in the fuel supply system, which should advantageously be arranged in the vicinity of the fuel feed pump. If the warming-up phase, during which the bulk of the fuel is conveyed only through the dirty space, is to be ended by an automatic control, this can preferably be done as a function of temperature or pressure.
  • a system suitable for carrying out the above-mentioned method with a customary preheating device for the heavy oil in the fuel supply system in front of the fuel feed pump is characterized in that the fuel filter has a dirty space with an inflow and an outflow and a clean room with another outflow, the dirty space on the inflow side with the pressure side the fuel feed pump and on the discharge side is connected to the fuel supply system - in front of a preheating device, while the discharge from the clean room leads to the fuel injection system.
  • shut-off device is provided in the drain from the dirty space, which can be designed as a pressure-maintaining valve or thermostatic valve, but can also be controlled independently in a version as a simple shut-off valve.
  • FIG. 1 and 2 each show a fuel filter 1 with a housing provided with a lid and a filter insert 5 in section.
  • the housing has an axial inflow 2 to the dirt chamber 8 and a radial outlet 3 from the dirt chamber 8 and a coaxial outlet 7 from the clean room 9 in the interior of the filter insert 5.
  • a return line 6 with a shut-off device 4 connects to the drain 3 from the clean room 9.
  • the shut-off device 4 is open. Only the dirt chamber 8 is flowed through from the inflow 2 to the outflow 3, while the fuel inside the filter insert 5 is still solid or viscous. After this fuel has been heated by the preheated fuel flowing past, the shut-off device 4 is closed and the fuel flows through the surface of the filter insert 5 via the drain 7 in the direction of the fuel injection system.
  • FIG. 3 shows a fuel tank 18 with a heating device 19, to which the suction side of a fuel feed pump 11 is connected via an intake line 10.
  • the pressure side of the fuel delivery pump 11 is connected to a fuel injection pump 14 via a delivery line, in which a fuel filter 1 is inserted.
  • An additional heating device 13 is arranged in the delivery line 12, which does not necessarily have to be present, but is advantageous in the case of long delivery lines for improved flowability of the fuel.
  • the delivery line 12 is connected on the one hand to the inflow 2 to the dirt chamber 8 and on the other hand to the outlet 7 from the clean room of the fuel filter.
  • a return line 6 to the fuel tank 8 connects to the drain 4 from the dirt chamber 8 of the fuel filter 1, into which a shut-off element 4 is inserted.
  • Individual injection lines 15 and a return line 16 extend from the fuel injection pump 14. In the return line 16, which opens into the return line 6 from the fuel filter 1, a pressure control valve 17 is used. The latter two lines 6, 16 can also be routed separately to the fuel tank 18.
  • the fuel tank 18 with the heating device 19, the fuel delivery pump 11 and the additional heating device 11 are generally arranged on the system side away from the internal combustion engine, while the other modules shown are arranged directly on the latter.
