2: University of Western Australia (U.W.A.) – November 2005
In conjunction with Rio Tinto’s Pilbara Iron Ore operations, fuel efficiency tests at UWA facility were conducted using generators fitted with fuel meters, load box facility and other test equipment to accurately measure fuel consumed for power produced.
Tests were conducted on both new and older engines to represent differing ages as would be expected in a general working environment. Two engines at a time were used, one as test whilst the second was used as the control engine to determine any climatic affected changes.
These tightly controlled tests proved the difficulties encountered when trying to accurately measure fuel consumption but by controlling as many of the variables as possible did provide evidence of fuel efficiency savings between 2% and 5.5%, dependant on engine and load, following FPC treatment of fuel.
