PTC heating for preheating of diesel fuel

Abstract

In diesel fuels, the long chained hydrocarbons (paraffins) precipitate at ambient temperatures below 0 °C. The fuel becomes viscous and can clog of the filter material. The increasing demands placed on filtration by modern common-rail injection calls for performance ranges for diesel fuel preheating that have not been achieved before now in the utility vehicle sector. This article describes the path taken by Eichenauer to develop a modern PTC heating system for preheating of diesel fuel for the Fuel Service Centre at Hengst with respect to the new common-rail diesel engines from MAN.
