1、IS0 13331:1995(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a sub

2、ject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (I

3、EC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Sta

6、0 13331:1995(E) Road vehicles - Filler pipes and openings of motor vehicle fuel tanks - Vapour recovery system 1 Scope This International Standard ensures compatibility be- tween new petrol-powered vehicle designs and refuelling vapour recovery nozzles - both active and passive systems - by their di

7、mensions and specifi- cations. NOTE 1 The dimensions and specifications of this Inter- national Standard are based on SAE J1140. This International Standard was developed primarily for passenger car and commercial vehicle applications but may be used in marine, industrial and similar applications wh

8、ere refuelling vapour recovery is re- quired. For national standards, see annex A. 2 Definitions For the purposes of this International Standard, the following definitions apply. 2.1 active vapour recovery system: System whereby the vapour is extracted during fuel filling by a powered form of extrac

9、tion, e.g. a vacuum pump. This system may require sealing of the filler pipe or may be the open type (not sealed). 2.2 passive vapour recovery system: System whereby the vapour leaving a fuel tank is emitted due to the volumetric displacement of the liquid fuel being added which relies on filler pip

10、e sealing to prevent loss of vapour. 2.3 filler pipe sealing surface: That part of the filler pipe against which a certain type of recovery nozzle can effect a vapour-tight seal (see figure 1). 2.4 nozzle test gauge: Gauge with dimensions as shown in figure6, used to establish the reference lines ar

11、ound which the filler pipe access zone is de- fined. 2.5 reference plane: Plane which contains the axial centreline of the filler pipe sealing surface, and is ro- tated into the direction which the manufacturer of the automobile has determined to be the orientation in which the nozzle is to be inser

12、ted. 2.6 normal resting position of nozzle test gauge: Gauge position when the following conditions are met. 2.6.1 The gauge is inserted into the filler pipe, such that the axial centreline of the gauge lies in the refer- ence plane. 2.6.2 The locking ring of the gauge is located im- mediately to th

13、e inside (i.e. the vehicle tank side) of the locking lip. 2.6.3 Either the gauge locking ring rests upon the filler pipe wall, or the gauge shaft rests upon the locking lip as shown in figures 2a) and 3a), respect- ively. 2.6.4 The fuel-dispensing end of the gauge, as indi- cated in figures 2a) and

14、3a), is in contact with a re- straining point. 2.7 insertion position of nozzle gauge: Gauge position when the following conditrons are met.

20、1 The filler pipe sealing surface shall meet the re- quirements of figure I. 3.2 An internal locking lip (see number 4 in figures 2 and 3) shall be provided around at least 100” of the inside circumference of the filler pipe. The locking lip shall be orientated such that it extends at least 35” to e

21、ither side of the reference plane. The height of the lip shall not be less than 2,5 mm measured from the inside wall of the filler pipe nor less than 8.5 mm as measured from the outside wall of the filler pipe if the outside diameter of the filler pipe is between 52 mm and 57,5 mm (see figure 1). Th

22、e depth of the lip shall be not less than 4 mm nor more than 13 mm into the filler pipe as measured in the reference plane, from the filler pipe sealing surface (designated n in figure 5, detail XI. 3.3 The filler pipe and all surrounding bumpers, body parts, and factory-installed accessories shall

23、be designed and fabricated so that the filler pipe access Q IS0 IS0 13331:1995(E) zone shall allow for insertion of a vapour recovery nozzle in at least one orientation within + 90” of the upright or vertical position. Allowance shall be made for production tolerances as these are not included in th

24、e access zone. The access zone consists of three parts as specified in 3.3.1 to 3.3.3. 3.3.1 A zone with an oval cross-section (see number 1 in figure41 that is fixed relative to the face of the filler pipe and designed to accommodate the sealing portion of a vapour recovery nozzle. The offset A (de

25、signated f in figure 5, section A-A) is equal to 0,004$ - 0,3c( + 2,O. expressed in millimetres, if the nozzle test gauge locking ring rests on the filler pipe wall in its normal resting position as illustrated in figure2a). tf the gauge shaft rests on the locking lip in its normal resting position

26、as is illustrated in figure3a), then offset A = 0,004a2 - 0,3a. + 0,l Id, expressed in millimetres, where d is the depth of the locking lip measured from the plane of the filler pipe sealing surface (designated n in figure5, detail X) in the reference plane, expressed in millimetres. Offset B (desig

27、nated g in figure5, section A-A) is equal to the number of degrees of angle /I x 0,4, expressed in millimetres. Offset B fails to exist for B 0. 3.3.2 A zone with a rectangular cross-section tapered at the bottom (see number 3 in figure41, that is designed to accommodate the handle portion of a vapo

28、ur recovery nozzle. This zone is the portion, shown in figure4, within the lines defined by points C, D, E, F and G. The bottom line of this zone (line C-D) is positioned relative to reference line A as shown in figure4. Reference line A is the nozzle test gauge centreline in the normal resting posi

29、tion as shown in figure4. The top of this zone (line G-F-E) is positioned relative to reference line B as shown in figure4. Reference line B is the nozzle test gauge centreline in the insertion position as shown in figure4. The centre P for the 190 mm, 240 mm and 306 mm radii, shown in figure 4, is

30、located by finding the intersection point of the 306 mm radius arcs struck from points D and E, respectively. 3.3.3 A transition zone (see number 2 in figure41 consisting of a smooth blend from the rectangular zone to the oval zone. The top of this transition zone is the line G-J in figures 4 and 5,

31、 and the bottom of this zone is line A-C. 3.4 The internal portions of the filler pipe shall be configured such that the nozzle test gauge can be in- serted far enough into the filler pipe to allow entrance of its locking ring beyond the filler pipe locking lip, and to allow movement of the gauge to

32、 the normal resting position and back to the released position. An un- leaded petrol restrictor shall be positioned so that the nozzle test gauge in the normal resting position pen- etrates the restrictor by at least 22,5 mm. The internal portions of the filler pipe shall also be configured to hold

33、the nozzle test gauge in a normal resting position such that the angle formed between the axial centreline of the nozzle test gauge and the axial centreline of the filler pipe sealing surface falls within the c( angle from + 20” to -10” as shown in figures 2a) and 3a). 3.5 As a minimum assurance aga

34、inst spillage, the filler pipe shall be orientated such that the axial centreline of the nozzle test gauge in the normal resting position forms an angle of not less than 30” with the horizontal plane, with the fuel-dispensing end pointing down. 3.6 Vapour outlet ports shall be positioned such as to

35、permit vapour recovery regardless of the system applied (e.g. active or passive).
