Abstract:
1. A system comprising: a diesel engine comprising a high pressure fuel injection system, the high pressure fuel injection system comprising an injector nozzle, wherein the high pressure fuel injection system is configured to operate at a fuel pressure at the injector nozzle in excess of 1000 bar and at a fuel temperature at a tip of the injector nozzle of 250 -350° C.; and a highly paraffinic distillate fuel composition configured for reducing formation of injector nozzle deposits in the high pressure fuel injection system when combusted in the diesel engine, wherein the highly paraffinic distillate fuel comprises a blend of individual components, wherein the hi hl paraffinic distillate fuel has a relative fouling behaviour of 70% or less, expressed as a percentage of a difference between fouling behaviors of the individual components and a fouling behavior of the highly paraffinic distillate fuel, and wherein the highly paraffinic distillate fuel has an aromatics content less than 0.1 wt %, a sulphur content less than 10 ppm and a paraffinic content of at least 70 wt %, and a density of more than 0.815 g. cm
