  • the tank may comprise a main reservoir, an auxiliary reservoir in which is situated a supply inlet for the feed pump and a top-up pump which in use is driven by the flow of fuel returned to the auxiliary reservoir to draw fuel from the main reservoir to the auxiliary reservoir and maintain the level of fuel in the auxiliary reservoir above that in the main reservoir, in which case the top-up pump conveniently comprises a venturi pump, fuel returning to the auxiliary ⁇ «reservoir drawing fuel through the venturi from the main reservoir.
  • the top-up pump may be driven by fuel in the return pipe or by fuel diverted from the flow delivered to the feed pipe by the feed pump

  • Fig. 6 is a view based on Fig. 5 and showing two modifications to the system shown in Fig. 5;
  • a fuel tank 11 comprises a main reservoir 12 and an auxiliary reservoir 13.
  • An electric motor driven feed pump 14 in the auxiliary reservoir 13 is operable to draw fuel from the tank 11 through a supply inlet 15 in the auxiliary reservoir.
  • a strainer 16 is provided to prevent dirt and debris entering the feed pump 14.
  • the feed pump 14 can supply fuel to a fuel injection device on an engine 17.
  • the fuel injection device comprises five unit injectors 18 which are supplied by an injector feed duct or fuel rail 20 on the engine 17.
  • the unit injectors 18 each combine a jerk type pump and injector as a single unit.
  • the fuel rail 20 is a longitudinal drilling in the cylinder head of the engine 17 and has an inlet 20A at one end and an outlet 2OB at the other end.
  • the return pipe 19 is connected to a top-up pump 21 situated in the auxiliary reservoir 13.
  • the top-up pump 21 is a venturi pump in which flow from the return pipe 19 enters a venturi which creates a depression which draws fuel from the main reservoir 12 through a strainer 22 and delivers it to the auxiliary tank through an outlet 23.
  • the top- up pump 21 is driven by the flow of fuel in the return pipe 19 and the level of fuel in the auxiliary reservoir 13 can rise above that in the main reservoir 12. This helps to ensure that the supply inlet 15 can receive fuel even when the level of fuel in the main reservoir 12 is very low or is fluctuating due to vehicle cornering or braking etc.
  • a separator baffle 24 divides the auxiliary reservoir 13 into a supply zone 25 where the supply inlet 15 is situated and a mixing zone 26 into which the top-up pump can discharge fuel.
  • the baffle 24 comprises a perforated plate which helps to allow any entrained air to escape in the mixing zone 26 and helps to mix the hot fuel returned by the engine with the cooler f el from the main tank 12.
  • a non-return valve 27 prevents fuel returning from the auxiliary tank 13 to the main tank 12.
  • a pressure regulator 28 is in the return pipe 19 to maintain pressure of the returned fuel at the engine above the pressure of fuel returned to the top-up pump 21 thereby reducing pressure at the venturi of the top-up pump.
  • Fuel supplied by the feed pump 14 is delivered to the injectors 18 through a feed pipe 31, a filter/separator 32 and a recirculation pump 33 by way of a feed/recirculation pipe 30 connecting the recirculation pump to the fuel rail inlet 20A.
  • a recirculation duct 34 connects the return pipe 19 and the feed pipe 31, the recirculation pump 33 causing fuel to recirculate from the outlet 20B of the fuel rail 20 to the inlet 20A.
  • the recirculation pump 33 is a venturi pump, the feed pump delivering fuel to the venturi where the reduced pressure draws fuel from the recirculation duct 34.
  • a fine filter 35 is provided upstream of the fuel rail 20 to catch any debris that may be circulated through the recirculation duct 34. Alternatively a fine filter 35A is positioned in the recirculation duct 34 itself.
  • the recirculation pump 33 and duct 34 allow the fuel flow in the injector rail 20 to be much higher than would otherwise be achieved.
  • the higher flow ensures that the fuel at the outlet 20B of the fuel rail 20 is only a few degrees higher in temperature than that at the inlet 20A.
  • the filter/separator 32 can be of a size which is sufficient only for the flow in the feed pipe 31 and is thus comparable to that used in a conventional fuel feed system.
  • the venturi of the feed pump 21 may be of a size which allows it to act as a restrictor orifice to control the flow rate in the return pipe 19. Alternatively or additionally a separate restrictor may be used.
  • the recirculation pump 33A is an electric motor driven pump which directly replaces the venturi type recirculation pump 33.
  • the pump 33A may be mechanically driven by the engine.
  • items which are the same as or similar to those in Fig. 1 have the same reference with the addition of 100.
  • the recirculation pump takes the form of an additional pump element 133 on the feed pump 114, driven by the same electric motor 136 which is submerged in the fuel for cooling and lubrication.
  • the pressure regulator 128 is in a T connection 137 in the recirculation duct 134 upstream of the recirculation pump 133 and is arranged with a deflector 138 to deflect any air bubbles into the pressure regulator and hence into the return pipe 119.
  • Operation of the first modified system is essentially the same as that described for the system shown in Fig. 1, the recirculation pump element 133 circulating fuel in the recirculation duct 134 while the engine is running.
  • the top-up pump venturi 321 uses flow diverted from the feed pump flow in the feed pipe 331 instead of flow in the return pipe connected to the recirculation duct as shown in
  • a heat exchanger 335 is in the recirculation duct 334 upstream of the filter/separator 332 and flow through this is controlled by a thermostat valve 336 which diverts flow through a bypass duct 337 connected in parallel with the heat exchanger when the temperature of fuel entering the thermostat valve is below a given temperature.
  • the pressure regulator 328 is placed upstream of the thermostat valve 336 which helps to reduce the pressure on the heat exchanger 335 and the filter/separator 332. Back pressure of fuel flowing through the thermostat valve 336 and the heat exchanger 335 also helps the operation of the pressure regulator 328.
  • the supply orifice is 319 is depicted diagrammatically in Fig. 4 as being in the wall of the auxiliary reservoir 313, a strainer and non-return valve similar to the strainer 22, 122, 222 and non-return valve 27, 127, 227 would be used in practice.
  • the injector fuel rail comprises a feed rail 320C and a return rail 320D, both formed as drillings in the cylinder head.
  • the filter/separator 332 is in the feed pipe 331 as in Figs. 1 to 4, but has a vent pipe 341 to vent air entrapped by the filter/separator to return to the tank.
  • the connection of the vent pipe 341 to the filter/separator 332 preferably incorporates a flow sensitive vent valve such as a jiggle pin of the type common in engine cooling systems. This is a normally open valve which has a low resistance to air flow but a higher resistance to the flow of liquid fuel. Hence any air or other gases or vapours are allowed to return to the tank 311 but the vent valve closes as soon as liquid fuel starts to flow.
  • the recirculation pump is upstream of the filter/separator 331 so that the feed/recirculation pipe has two portions 330A and 3OB.
  • Operation of the third modified system is essentially the same as that described for the system shown in Fig. 1, the recirculation pump element 333 circulating fuel in the recirculation duct 334 while the engine is running.
  • the feed pump is a conventional type in which fuel is taken from the tank through an inlet in the lower wall of the pump and is pumped through the motor itself over the motor armature, brushes and commutator. This helps to cool and lubricate the brushes and allows the motor to be rated for continuous operation over a long period.
  • the feed pump is of the same conventional type but is a two rotor design normally used as a straightforward two stage pump to give higher pressure.
  • the feed pump 114, 214 or 314 is normally the low pressure pump and is typically an impeller pump and the recirculation pump 133, 233 or 333 is normally the high pressure pump and is typically a two rotor internal gear type, sometimes known as a gerotor.
  • the arrangement shown in Figs. 3 to 5 has the drawback that the fuel circulated over the motor 136, 236 or 336 is hot fuel in the recirculation duct 134, 234 or 334 and the increased temperature has an adverse effect on the service life of the motor.
  • the outlet from the feed pump 314 is taken by a duct 331A through the motor 336 so that the motor benefits from the relatively cool fuel taken from the auxiliary reservoir 313.
  • the duct 331A may be an external pipe as shown but may also be a passage in the stator of the recirculation pump 333 or an annular passage formed between the stator of the recirculation pump 333 and an outer casing.
  • the other modification is that the filter/separator 332A is at the junction of the recirculation duct 334 and the feed pipe 331. This puts to the filter/separator 332A the full flow of fuel pumped to the engine 317 through the feed/recirculation pipe 330A and 330B but can allow for better filtration and air venting.
  • the invention may also be applied to diesel engines with separate injector pumps or to petrol/gasoline engines with multi or single point injection.

Abstract

Un système d'alimentation en carburant d'un moteur à combustion interne (17) comprend des injecteurs unitaires (18) alimentés par un conduit d'acheminement de carburant (20). Ce système comprend un réservoir (11) et une pompe d'alimentation entraînée par un moteur (14) et placée dans un réservoir auxiliaire (13). Un tuyau de renvoi (19) renvoie le carburant au réservoir auxiliaire (13) par une pompe d'appoint de type venturi (212) qui aspire le carburant d'un réservoir principal (12) par l'intermédiaire d'un clapet de non-retour (27). Une pompe de recirculation de type venturi (33) fait recirculer le carburant dans un conduit de recirculation (34), ce conduit étant raccordé à un tuyau de renvoi (19). Dans une autre variante (Fig. 2), la pompe de recirculation est entraînée par un moteur électrique. Selon encore une autre variante, le pompe de recirculation comprend un élément de pompage supplémentaire placé sur la pompe d'alimentation.
