Our new paper in Fuel investigates the source of internal injector deposits in diesel injectors - a nasty problem that may be the source of a significant chunk of the soot emissions from diesel cars, and not only - NO_x and CO₂ emissions are also affected.

The nature of the diesel injector deposits suggests one rather unexpected source - the earthing current, a safety measure that protects the engine against sparks produced by a streaming currents carried by the injected fuel (a problem that appears in many other hydraulic devices, not only fuel injectors).

But will this hypothesis stand an experimental test?
