The complexity of the deposits formation process on the components of compression ignition engine, including high-pressure injection Common Rail systems, is gaining global significance. Knowledge related to the mechanisms of their formation and chemical composition is still insufficient and requires further studies. The studies allowed, hypothetically, assuming several mechanisms of their formation, but each of these require further research in order to be verified and finally confirmed. This is due to high complexity of the factors and conditions that may affect the initiation of the deposit formation, of which the most important are: fuel and additive composition and type of contaminants from fuel production and transport. Deposits’ physical nature may vary, as these may be soaps, salts of metals or ashless materials like imide or amide forms of organic polymers. This article contains the results of the research on the assessment of HP Common Rail injector and EGR components contamination and their technical condition, after 120 thousand km operational run, with the use of diesel and biofuel B10.
