Both measurements were taken in the same fleet diagnostics bay, with the engine at operating temperature.
How the work on the bus proceeded
| STAGE | DATE | DETAILS |
|---|---|---|
| Diagnostics before treatment | 25.09.2002 | Power at operating temperature 80 kW, smoke opacity 83.3 % |
| Engine treatment | September 2002 | XADO Revitalizant gel for diesel engines, three stages, no teardown |
| Service operation | 33 days | Over 4000 km on city routes, the bus was never taken off the line |
| Diagnostics after treatment | 28.10.2002 | Power at operating temperature 96 kW |
The engine was treated in place on the bus: no teardown, no parts replacement and no downtime were required.
What the report recorded
At the diagnostics bay of JSC Avtokolonna No. 1118 on 25.09.2002, the Volvo B10M60 bus showed power at operating temperature of 80 kW and smoke opacity of 83.3 % — the condition of a worn city bus diesel. The engine was treated with XADO Revitalizant gel in three stages, without removing it from the vehicle and without teardown. The bus stayed in route service; after 33 days and over 4000 km a repeat measurement in the same bay gave 96 kW — 20 % above the initial figure. The gain was obtained without replacing any parts: the metal-ceramic layer builds up exactly where the cylinder-piston surfaces are worn, restores sealing — and the engine delivers its power again. The report was approved by the technical director of the company and certified with the stamps of the bus fleet and of the contractor that performed the treatment.
The results refer to the diesel engine of a Volvo B10M60 bus in city service; on other equipment and under different conditions the figures may differ. The original report of JSC Avtokolonna No. 1118 dated 29.10.2002, with signatures and stamps, is published in full and available for download.
