Abstract
A method of reducing the impact of deposits in a post combustion system of a diesel engine. The method comprises combusting in the engine a diesel fuel composition comprising as additives: (a) one or more quaternary ammonium salts; and (b) one or more compounds which are a product of a Mannich reaction between an (b1) aldehyde, (b2) an amine and (b3) an optionally substituted phenol. The method may be particularly effective when combusting a diesel fuel composition comprising renewable diesel.
