Low Temperature Operability of Diesel Vehicles 890048

Low temperature waxing of diesel vehicles is of continuing concern to vehicle manufacturers, fleet operators and diesel vehicle drivers. However, significant progress has been and is being made in addressing their needs for better protection against waxing problems in winter.In the past two years a new generation of fuel additive technology has become available which offers further improvements in performance over that produced by conventional flow improvers. Wax Anti-settling Flow Improvers (WAFI) modify the wax crystals so that they remain dispersed rather than settling to the bottom of the fuel tank. This paper presents data from field and dynamometer tests demonstrating the lower minimum operability temperatures resulting from use of these additives.
