Abstract
A process for reducing injector deposits in an internal combustion engine fuelled with a fuel composition, the process comprising contacting a fuel composition with a metal-selective membrane situated in the fuel delivery system. The reduction of such deposits provides an increase in fuel efficiency, fuel thermal stability, boost in engine cleanliness, improves fuel economy and enables the possibility of using a reduced amount of expensive detergent in the fuel composition.
