Definitions

  • the present invention relates to a method for refuelling of gas driven vehicles, particularly buses and lorries, from a gas fuelling station having a compressor plant and/or a gas store able to supply gas at a high pressure to a vehicle gas container having two openings. Furthermore the present invention also relates to a system for carrying out the method and to a vehicle gas container being part of the system.
  • the gas fuel container of the vehicle is normally of a so called composite construction, i.e. the container has an inside tube which as such does not stand the requested pressure but is embedded in an outside fibre clad comprising an epoxy resine.
  • Such a composite container has two openings, one at each end of the container. Smaller containers, having a length of up to say 1,5 meter, has got one of the openings plugged. If the container length is more than 1,5 meter the authorities stipulate that each one of the openings is equipped with a thermal release mechanism discharging the gas in case of fire. If such a release mechanism was missing there will be a great risk for having a fast pressure rise inside the container which in such a case results in an explosion.
  • Containers of composite type are rather expensive compared to steel containers but they hav quite other safety qualities motivating their usage.
  • the intention with the present invention is to speed up the refuelling of gas driven vehicles and to solve the problems mentioned above.
  • larger gas containers only a small number of containers is needed per vehicle which reduces the installation costs.
  • the object of the present invention has been solved by a method and a system for refuelling of gas driven vehicles where the two openings of the vehicle gas container is used in such a way that the refuelling of gas is made simultaneously in opposite directions to the container.
  • a suitable vehicle gas container according to the invention is equipped in such a way that it is possible to refuel it from two opposite directions simultaneously.
  • the refuelling of the container is made step by step as the container is divided in separate sections used one at a time for driving of the vehicle.
  • Each section of the vehicle gas container of the preferred embodiment is equipped with two openings having refuelling valves, but only one of these two openings is equipped with a feeding valve for gas supply of the vehicle engine.
  • a method for refuelling of a natural gas driven vehicle (NGV) E is shown in Fig. 1.
  • NSV natural gas driven vehicle
  • Such a method may make use of a compressor plant CP, a gas store GS or the like.
  • Fig. 1 a schematical view is shown of the compressor plant CP being of a traditional type including a CNG compressor 10, a safety valve 11, a pressure gauge 12 for the compressor pressure, a condenser and dryer 13, a filter 15, and a pressure maintaining valve 14.
  • Fig. 2 shows a type of gas store GS for natural gas which can be charged from a gas source or a compressor plant CP.
  • the gas store GS is divided in att least two sections (in the present embodiment in three sections 20, 21, 22) or banks.
  • Each section 20 - 22 may in turn include two or more cylinders A, B.
  • the gas supply to and from each one of the sections 20 - 22 is controlled by a cylinder valve 23 the input of which is connected to a filling line FL from the gas source or compressor plant.
  • the cylinder valve 23 input is also used as an output connected to a refuelling line RL connectable to the gas driven vehicle E (Fig.
  • the cylinder valves 23 as well as the break away valves 24 are in connection with an evacuation line 27 taking care of overpressure situations with respect to the safety case.
  • the gas store GS is favourably constructed for so called cascade refuelling.Thus, said at least two sections or banks 20 - 22 of the gas store GS are working with different pressures. Then the first section 20 - having the lower pressure - is used for bottom refuelling of the gas driven vehicle container. The second section 21 - having higher pressure - and eventual further sections 22 - having still higher pressures - are used in steps for refuelling the gas driven vehicle container step by step with higher fuel pressure after closing off the the section(s) 20 (21) with lower pressure. This way of refuelling means that more vehicles can be refuelled before the pressure of the gas store GS has dropped to a level below a predetermined lowest pressure value.
  • the cascade refuelling is controlled by the check valves 26 being of solenoid valve type having manual bypass and being introduced in the refuelling line RL.
  • the refuelling line RL comprises a temperature compensation arrangement 30.
  • the temperature compensation arrangement 30 includes two control branches 31, 32, one 32 of which comprises a temperature compensated pressure regulator 33 acted on by a reference pressure tank 34 for the temperature compensated refuelling pressure.
  • the other branch 31 comprises a temperature compensated safety valve 35 acted on by a reference pressure tank 36 having a pressure value of P+10%.
  • Fig. 3 shows a preferred of the vehicle gas container 40 of the present invention.
  • the vehicle gas container 40 is divided in two sections 40A, 40B each one including three separate gas cylinders 41, 42, 43.
  • Each gas cylinder 41, 42, 43 is made in form of a composite container having two openings 44, 45 situated att opposite ends of the gas cylinder 41, 42, 43. Both the openings 44, 45 are equipped with a refuelling valve, but only one 44 of the openings is equipped with a feeding valve for supplying gas to the gas driven vehicle engine E through the feeding line FL.
  • each gas cylinder 41, 42, 43 is refuelled simultaneously in two directions opposite each other through the refuelling line RL from the gas store GS described above with reference to Figs. 1 and 2.
  • the gas supplying device including a feeding valve of the type similar to the one connected to the gas cylinder opening 44 may be of the type described in the prior patent applications EP-A-01 202 724.9 and EP-A-03 445 127.8 filed by the present applicant. These applications also describe the system of gas supply to the gas driven motor M within the engine compartment E involving a solenoid valve 46 controlling a low pressure pilot line 47, a dumping cylinder 48, a check valve 49, a filter 50, and a manually operated stop valve 51.
  • Such a stepped feeding method may be controlled by pressure sensors.
  • the stepped feeding method is favourable later on when the vehicle arrives at the refuelling station.
  • a gas store GS constructed for so called cascade refuelling, as described above, the contribution of the gas store high pressure sections is less and it will be possible to use the gas store GS for consecutive or simultaneous refuelling of a greater number of vehicles, i.e. a smaller gas store GS can be used for the very same number of vehicles without impairing the refuelling time.
