Abstract: The invention concerns a method for supplying iron, via the fuel, to the particulate trap of a diesel engine exhaust in a form suitable for promoting trap regeneration.

The method is thus particularly suitable for modern engines showing increased susceptibility to fuel injector deposits. The colloid also shows a balance of properties providing excellent suitability for use as an additive in fuels, and especially in diesel engine on-board dosing devices.
