Ford's urea-diesel co-fueling scheme comes in heavy-duty, light-duty nozzle versions

Diesel Fuel News, March 18, 2002

The heavy-duty vehicle nozzle design (SAE 2002-01-0290) still must be optimized, as today's version could restrict gallons-per-minute (gpm) diesel flow rates by about 10-15%. So, Ford aims to enlarge the nozzle size (see Diesel Fuel News 8/20/2001, p1), taking advantage of the larger fuel-filler-holes on diesel trucks; this would eliminate potential truck-stop congestion due to slower-than-normal gpm diesel refueling rates.

GPM rate for light-duty application with the urea/diesel nozzle doesn't suffer, Ford found. As for nozzle-tip urea crystallization/deposition problems, it may be possible to solve this by mechanical means, such that every time a customer inserts the nozzle into a tank, the coupler for urea connection could chip-off whatever crystals may be plugging the nozzle, Ford urea-SCR tech developer Dick Baker explains.
