IE A093REPORT ON MEASUREMENTS BEFORE AND AFTER TREATMENT WITH XADO TECHNOLOGY
TGM-40 locomotive: compression and oil pressure up without teardown
Compression rose in every cylinder of the row, oil pressure in the lubrication system rose. 12–21.7 % — compression on all 12 cylinders, 23–25 → 28; 17.3 % — oil pressure at 45 °C, 5.2 → 6.1 kgf/cm² (2001).

Compression is recorded in the report without a unit of measurement, so the change for each cylinder is given in relative terms.
Oil pressure in the engine lubrication system
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT | CHANGE |
|---|---|---|---|
| Oil pressure at an oil temperature of 45 °C | 5.2 kgf/cm² | 6.1 kgf/cm² | +17.3 % |
Higher pressure in the lubrication system indicates restored clearances in the engine friction pairs.
