Abstract

In the paper the different quality grades of diesel fuels of low sulphur and reduced aromatic content are summarized on the base of various degrees of reduction in sulphur and aromatic content. The effects of reduction in sulphur and aromatic content on exhaust gas emissions, fuel consumption and wear of fuel pump and other parts of engine are presented. The possibilities for reducing and eliminating the disadvantageous properties (wear of the fuel pump and injection system, excess fuel consumption, etc.) by using different types of additives (cetane number improver, lubricity improver, etc.) are discussed. The improvement in lubricity of reformulated and additive containing diesel fuels is presented on the base of results of High Frequency Reciprocating Rig (HFRR) test.
