【 摘 要 】

The article describes damages to high pressure injectors used in common rail injection systems. The conducted analysis of their causes includes the diagnosis of injectors on a test bench and the results of microscopic research of damaged components. The tribological damages of high pressure injectors are local and cavitations pitting. The place of cavitations pitting are mainly check valves, where the reduction in the quantity of injected fuel is forming.
