The analysis of mechanical damage of common rail injectors

Abstract

The paper presents the causes and effects of corrosion, destructively affecting the technical condition and operational reliability of injectors used in Common Rail supply systems. In addition, the analysis was made regarding damage to compression-ignition (diesel) engines with common-rail supply systems occurring in the operation of injectors caused by ex-ternal and internal operating factors. Studies on injection equipment wear were carried out with the use of Hitachi S-3400 scanning electron microscope. Photos were also taken at the repair workshop of the needle surface and the socket using D.O. Smart digital microscope with specialized fibre optic lighting. Worn components were analyzed, indicating the elements most frequently subject to destructive processes. The possibilities of diagnosing subassemblies of Common Rail injection systems were indicated.
