compression across the cylinders, 28-29 → 31 atm
| EQUIPMENT | MILEAGE AT TEST START | WHAT WAS MEASURED |
|---|---|---|
| MAN TGA, MAN D 2866 diesel, plate No. AX 4493 AT | 1 069 013 km | Compression in all six cylinders, atm |
Compression by cylinder, MAN D 2866 diesel
| CYLINDER | BEFORE, ATM | AFTER, ATM | CHANGE, ATM |
|---|---|---|---|
| Cylinder 1 | 28 | 31 | +3 |
| Cylinder 2 | 28 | 31 | +3 |
| Cylinder 3 | 29 | 31 | +2 |
| Cylinder 4 | 29 | 31 | +2 |
| Cylinder 5 | 29 | 31 | +2 |
| Cylinder 6 | 28 | 31 | +3 |
All six cylinders reached one and the same value — 31 atm. Compression is capped by the factory rating, so this common level across all cylinders is the limit of the achievable result.
Conclusion of the act
The commission of Transservice LLC — the director, the chief mechanic and the engine fitter — recorded in the act: "Application of the Atomic Metal Conditioner 'XADO 1Stage Maximum for Diesel Truck' led to the evening out (removal of the spread) of compression and to its increase by an average of 2.5 units, and accordingly to a rise in engine power of 4-5 %". By the start of the test the engine had run over a million kilometres; the treatment was carried out without teardown — by adding the formulation into the 40 l oil system. After a year of service, compression rose in all six cylinders and levelled off at 31 atm: the tightness of the cylinder-piston group was restored, and with it the power and smooth running of the diesel.
The results refer to the MAN D 2866 diesel of a MAN TGA truck with over one million kilometres of mileage; with a different engine condition and operating modes the figures may differ. The original technical act with signatures and stamps is published in full and available for download.
