7、 for refuelling road vehicles, and their filling rates. It applies to nozzle spouts for leaded gasoline and diesel fuel for road vehicles. 2 Reference IS0 4130, Road vehicles - Three-dimensional reference systems and fiducial marks - Definitions. 3 Requirements The nozzle spout shall conform to the
8、dimensions given in the figure. The shape is at the manufacturers discretion. The flow rate, qv, shall be qv 50 Vmin for leaded gasoline; qv 50 Vmin or 50 Vmin qv 100 Vmin for diesel fuel, depending on spout dimensions (see the figure). The figure shows a nozzle spout with a spring for safe hooking
9、in the tank filler opening. The dimensions apply also to nozzle spouts with cams or depressions for safe hooking.
