Definitions

  • the fuel supply system for internal combustion engines remains the subject of the invention.
  • supplying LPG to engines is executed by means of the same electronic control unit as well as the same original petrol/Diesel oil supplying system by placing a connector pipe on the high pressure pump, which prevents an LPG powered engine from gasing through an excess fluid return line and closes the supply of petrol or Diesel oil to the high pressure pump while the engine operates on LPG , which is then supplied to the pump in liquid state.
  • the description of a Polish patent PL 210816 presents a solution in which electric energy is transferred from a liquid fuel injecting system controller to a gas fuel injector .
  • the fuel supply system for internal combustion engines is equipped with a fuel type switch placed at least before one of the pumps supplying fuel to the high pressure pump, behind which a valve receiving the impulses from a fuel pressure sensor and a fuel temperature sensor is placed.
  • the valve is mounted on a return line connecting the high pressure pump with a connecting pipe supplying fuel to a damping nozzle initiated by the valve.
  • the system solves the problem of supplying fuel with the pressure occurring inside the LPG tank , which is noticeably lower than applied so far and hence makes it possible to use one system to supply an engine with selected type of fuel ( LPG, petrol/ Diesel oil).
  • the subject of the invention has been presented in the figures to demonstrate exemplary manufacturing.
  • the figure presents the schematic drawing of the engine fuel supply system (fig. 1) and the cross-section of the multivalve ( fig. 2).
  • Engine fuel supply system possesses the fuel type switch (1), which enables an operator to make a choice between LPG and petrol/Diesel oil.
  • Switch number 1 is placed before a pump (2) which supplies a selected type of fuel to the high pressure pump (3), from where the engine is fed directly.
  • the return line extracts from the high pressure pump (3) and it houses a valve (4) placed directly behind the pump number 3.
  • the valve number 4 receives the controlling impulses from sensors number 8 and 9.
  • Sensor number 8 measures the fuel pressure inside the return line while sensor number 9 measures the fuel temperature there. When there is LPG fuel inside the supply system, the pressure value and the temperature are proper. The parameters are different in case of petrol/Diesel oil.
  • valve number 7 By selecting a proper damping nozzle (6) and controlling the capacity of pump number 2, we achieve the demanded pressure and flow rate.
  • the return line is connected by means of connector pipe (5) supplying the fuel to the damping nozzle (6), activated by valve number 7.
  • valve number 7 opens the flow that circumvents the damping nozzle (6).
  • LPG fuel inside the system is emptied in no time.
  • sensors number 8 and 9 read it and transfer the information to valve number 4 which closes the return line and cuts off the fuel return to LPG tank.
  • valve number 4 opens the return line and valve number 7 forces the flow through the damping nozzle (6)
