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 .
  • 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.

Abstract

Le système d'alimentation en carburant pour moteurs à combustion interne, qui utilise en alternance le GPL et l'essence/gazole, est équipé d'un commutateur (1) de sélection du type de carburant situé avant la pompe (2). La soupape commandée (4) est placée derrière la pompe à haute pression (3). Elle bloque le retour de carburant vers le réservoir une fois le type de carburant sélectionné par commutation.
