Description

ADDITIVE EXPLOSION RISK Technical fieldThe invention relates to a fuel dispensing unit for refueling vehicles andto a method for handling a fuel dispensing unit.
Background artSafety aspects in and around areas containing fuel dispensing units is today a highly debated field and new technology is constantly developed withthe intention to increase the safety within such areas. lt is well-known thatfuel, such as petrol or diesel, is a highly inflammable substance that must behandled with extreme care. An inherent property of fuel, that increases therisks of its handling, is its high volatility. For the above reasons, safetystandards such as the UL standards for safety in North America, the ATEXdirective in the EU or the European standard EN 13617 pertaining to petrolfilling stations have been created for fuel handling to reduce the therebyinduced risks.
According to those standards, electromechanical devices, such as themotor or the above mentioned switching device, must be enclosed inexplosion-proof housings or isolated through the use of intrinsically safecircuitry in order to protect against the hazards of a spark igniting fuel vapors.
Although serious measures have been taken to ensure the safety it isalways a concern when highly inflammable substances are handled aroundfuel dispensing units. ln today”s conventional fuel dispensing units it is common that anadditive is added to the fuel of the fuel dispensing unit for various reasons.The additive constitutes a highly inflammable substance and is normally heldin a container which is placed in connection to the fuel dispensing unit and isconnected thereto.
The additive is pumped into the fuel at a pressure side of a fuel pumpinside the fuel dispensing unit. The additive itself is pumped by means of apump driven by a motor.
A problem with this solution is that new regulations states that theadditive is no longer allowed to be pressurized in concentrated form due tothe risk of explosion.
Summary of the invention lt is an objective of the present invention to mitigate, alleviate oreliminate one or more of the above-identified deficiencies in the art anddisadvantages singly or in any combination and solve at least the abovementioned problems.
According to a first aspect of the invention, these and other objects areachieved, in full or at least in part, by a fuel dispensing unit for refuelingvehicles. The fuel dispensing unit comprises an underground tank for holdingfuel, a fuel conduit for transporting the fuel, the fuel conduit extendingbetween the underground tank and a hose connection, a pump arranged onthe fuel conduit, the pump having a suction side and a pressure side, anadditive tank for holding additive, and an additive conduit for transporting theadditive. The additive conduit extends between the additive tank and the fuelconduit. The fuel dispensing unit is characterized in that the additive conduitis connected to the fuel conduit on the suction side of the pump.
Since the additive enters the fuel conduit at the suction side of thepump, it is no longer pressurized in concentrated form. ln other words, theadditive is mixed into the fuel present in the fuel conduit before beingpressurized by means of the pump.
This is advantageous in that the risk of explosion is eliminated. Anotheradvantage is that the need for an additional pump and motor for pumping theadditive in the fuel dispensing unit is removed.
The fuel dispensing unit may further comprise a flow meter and acontrol valve arranged in series in the additive conduit.
The fuel dispensing unit may further comprise a control unit connectedto the flow meter and a control valve.
The control unit may be adapted to control the control valve based onthe volume of fuel present in a fuel flow path of the fuel dispensing unit when a refuelling process is initiated to compensate for lack of additive in thatvolume of fuel.
The volume of fuel present between the nozzle of the fuel dispensingunit and the additive injection point of the system, i.e. where the additiveconduit connects with the fuel conduit, is known. ln one embodiment, thecontrol valve in the additive conduit is set to distribute a higher level ofadditive for the first 5 litres of fuel to compensate for the lack of additive in thefuel present in the system when the refuelling process is initiated. lf thepreceding refuelling process in the system included additive, no suchcompensation will be necessary.
The fuel dispensing unit may further comprise a flow meter arranged inthe fuel conduit at the suction side of the pump, wherein the control unit isconnected to the flow meter arranged in the fuel conduit.
The control unit may be adapted to control the control valve based oninformation from the flow meter arranged in the additive conduit and from theflow meter arranged in the fuel conduit.
The fuel dispensing unit may further comprise bypass channelextending between the pressure side and the suction side of the pump on thefuel conduit, the bypass channel comprising a control valve.
The pump and the flow meter arranged in the fuel conduit may bearranged in a hydraulics compartment of the fuel dispensing unit.
The additive tank, and the flow meter and the control valve arranged inthe additive conduit, may be arranged in an additive compartment.
The additive compartment may be arranged in an opposite side to thehydraulics compartment of the fuel dispensing.
The fuel dispensing unit may further comprise a nozzle connected tothe hose connection via a hose.
According to a second aspect of the invention, these and other objects,and/or advantages that will be apparent from the following description ofembodiments, are achieved, in full or at least in part, by a method for handlinga fuel pump unit for a fuel dispensing unit. The fuel dispensing unit comprisesan underground tank for holding fuel, a fuel conduit for transporting fuel, thefuel conduit extending between the underground tank and a hose connection, a pump arranged on the fuel conduit, the pump having a suction side and apressure side, an additive tank for holding additive, an additive conduit fortransporting additive. The additive conduit extending between the additivetank and the fuel conduit. The method is characterized by the step ofconnecting the additive conduit to the fuel conduit at the suction side (S) ofthe pump.
The method may further comprise the step of controlling the controlvalve arranged in the additive conduit based on the volume of fuel present inthe fuel flow path of the fuel dispensing unit when a refuelling process isinitiated to compensate for lack of additive in that volume of fuel.
The method may further comprise the step of controlling a control valvearranged in the additive conduit based on information from a flow meterarranged in the additive conduit and information from a flow meter arranged inthe fuel conduit.

Brief description of the drawinds The above, as well as additional objects, features and advantages ofthe present invention, will be better understood through the followingillustrative and non-limiting detailed description of embodiments of the presentinvention, with reference to the appended drawings, where the samereference numerals may be used for similar elements, and wherein: Fig. 1 is a perspective view of one exemplary embodiment of a fueldispensing unit for refueling vehicles according to a first aspect of theinvenfion.
Fig. 2 is another perspective view of one exemplary embodiment of thefuel dispensing unit for refueling vehicles according to the first aspect of theinvenfion.
Detailed description of preferred embodiments of the invention Fig. 1 illustrates an exemplary embodiment of a fuel dispensing unit 1for refueling vehicles. The fuel dispensing unit 1 has hose storage spaces 2on each opposing side of the fuel dispensing unit 1, an electrical compartment3 containing all the electronics for the fuel dispensing unit 1, a hydrauliccompartment 4 containing fuel dispensing means (not shown), e.g. fuelmetering means, valves, vapour recovery system etc., and a column 5extending vertically between and separating the electrical compartment 3 andthe hydraulic compartment 4 from the hose storage spaces 2. The fueldispensing unit 1 also has an additive compartment 6 which is arranged on anopposite side of the fuel dispensing unit 1 in relation to the hydraulicscompartment 4.
When filling up the tank of a motor vehicle, the fuel is pumped from anunderground tank 7 by means of a pump 8 which is located in the hydrauliccompartment 4, and from there to the column 5 and out to a nozzle 9 via ahose connected 10 to the hose connection 11.
The fuel dispensing unit 1 has a nozzle boot 12 in which the nozzle 9 isarranged when not in use. The nozzle boot 12 preferably comprises a sensor(not shown) for detecting if the nozzle 9 is present in the nozzle boot 12.Further, the nozzle 9 is normally equipped with a flow meter (not shown) formeasuring the fuel flow rate from the nozzle 9 upon refuelling.
Fig. 2 illustrates the fuel dispensing unit 1 from a see throughperspective. The fuel dispensing unit 1 comprises the underground tank 7 forholding fuel and a fuel conduit 13 for transporting the fuel. The fuel conduit 13extends between the underground tank 7 and the hose connection 11. Thefuel dispensing unit 1 further comprises the pump 8 arranged on the fuelconduit 13, the pump having a suction side S and a pressure side P, anadditive tank 14 for holding additive, and an additive conduit 15 fortransporting the additive. The additive conduit 15 extends between theadditive tank 14 and the fuel conduit 13 and is connected the fuel conduit 13at the suction side S of the pump 8. ln this embodiment, a flow meter 16 and a control valve 17 arearranged in series in the additive conduit 15. The fuel dispensing unit 1 alsocomprises a control unit 18 which is connected to the flow meter 16 and thecontrol valve 17. The control unit 18 is used to control the flow of additivethrough the additive conduit 15 by means of the control valve 17.
The control unit 18 may for example be adapted to control the controlvalve 17 based on the volume of fuel present in a fuel flow path of the fueldispensing unit 1 when a refuelling process is initiated to compensate for lackof additive in that volume of fuel.
More specifically, since the volume of fuel present between a nozzle 9of the fuel dispensing unit 1 and the additive injection point of the system, i.e.where the additive conduit connects with the fuel conduit 13, is known, thecontrol valve 17 in the additive conduit 15 may be set to distribute a higherlevel of additive for a predetermined number litres of fuel to compensate forthe lack of additive in the fuel present in the system when the refuellingprocess is initiated. lf the preceding refuelling process in the system includedadditive, no such compensation is necessary. The predetermined number of litre is established based on the volume of fuel present in the system whenthe refuelling process is initiated.
Optionally, a flow meter 19 is arranged in the fuel conduit at the suctionside S of the pump 8. ln this case, the control unit 18 is connected to the flowmeter 19 arranged in the fuel conduit 13. This way, the control unit 18 may beadapted to control the control valve 17 based on information from the flowmeter 16 arranged in the additive conduit and from the flow meter 13arranged in the fuel conduit. ln other words, the control valve 17 in theadditive conduit 15 may be set to distribute a level of additive which is basedon the fuel flow rate detected by the flow meter in the fuel conduit 13.
Naturally, the control unit 18 may be adapted to combine the differentsolutions described above in order to give the best possible accuracy of theratio blending. ln other words, the control unit 18 may be adapted to controlthe control valve 17 based on information from both the flow meter 16 and theflow meter 19, as well as, simultaneously compensating for the potential forthe lack of additive in the fuel volume present in the system when therefuelling process is initiated.
The fuel dispensing unit 1 may also further comprise a bypass channel20 extending between the pressure side P and the suction side S of the pump8 on the fuel conduit 13, wherein the bypass channel 20 comprises a controlvalve 21. During simultaneous fuelling, the control valve 21 in the bypasschannel 20 is closed or open at a small opening degree. However, when thefuel dispensing unit 1 is used to deliver fuel from only one nozzle 9, abackpressure develops and causes the control valve 21 to open. Thereby, aportion of the pumped fuel is recirculated to the inlet of the pump 8.
The pump 8 and the flow meter 13 arranged in the fuel conduit arearranged in a hydraulics compartment 4 of the fuel dispensing unit 1, whilethe additive tank 14, and the flow meter 16 and the control valve 17 arrangedin the additive conduit 15, are arranged in an additive compartment 6. Theadditive compartment 6 is in this embodiment arranged at an opposite side tothe hydraulics compartment 4 of the fuel dispensing unit 1. lt is understood that other variations in the present invention arecontemplated and in some instances, some features of the invention can be employed without a corresponding use of other features. Accordingly, it isappropriate that the appended claims be construed broadly in a mannerconsistent with the scope of the invention.
For instance,the control valve 17 may be constituted by an on-offvalve, a proportional valve, or another device for adjusting the additive flowrate in the additive conduit 15.
The pump 8 may be connected to a pump motor which drives the samebut it may also include a pump motor in itself.
