The Cold Filter Plugging Point method is used to describe the procedures for determining low-temperature operability in diesel fuel, biodiesel, blends and gas oils. The CFPP is a critical property used to forecast the lowest temperature at which a fuel will freely flow through filters in a diesel engine system.
All diesel fuels contain wax. At some points wax crystals will begin to precipitate when the temperature of the fuel decreases. If a certain amount of wax precipitates, the crystals can block fuel flow through filters and other restricted passages in the fuel system.
