Key results
↑6.1%
oil pressure on a warmed-up engine, 3.3 → 3.5 bar
↓1.5-2°C
cylinder head temperature, 55–60 → 53–58 °C
| EQUIPMENT | HOURS AT START OF TESTS | WHAT WAS MEASURED |
|---|---|---|
| KATO F 399 DE truck crane, six-cylinder diesel | 47 151 engine hours, in service since 1991 | Cylinder head temperature 1–6, oil pressure, ultrasonic noise and knocking, vibration |
Measurements before and after treatment — KATO F 399 DE crane diesel
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Cylinder 1 head temperature | 55 °C | 53 °C |
| Cylinder 2 head temperature | 57 °C | 55 °C |
| Cylinder 3 head temperature | 58.5 °C | 57 °C |
| Cylinder 4 head temperature | 60 °C | 58 °C |
| Cylinder 5 head temperature | 60 °C | 58 °C |
| Cylinder 6 head temperature | 57 °C | 55 °C |
| Oil pressure, idle 700 rpm | 3.3 bar | 3.5 bar |
The temperature drop was recorded on all six cylinders; measurements were taken cylinder by cylinder on a warmed-up engine at an oil temperature of 50 °C.
Engine condition as recorded by the commission
| INDICATION | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Elevated ultrasonic noise | In cylinder 4 | Absent |
| Isolated knocking | In cylinder 4 | Not observed |
| Vibration | Present | Absent |
| Oil burn-off consumption | Elevated | Decreased |
The defect in cylinder 4 — ultrasonic noise and knocking — was recorded by the commission BEFORE treatment; the engine was not disassembled.
Commission conclusion
The Kazzinc JSC commission recorded in the report: "increased compression in the cylinder-piston group (CPG), an increase in oil pressure of 0.2 bar on a warmed-up engine, reduced oil burn-off consumption". The commission attributes the lower noise and vibration and the higher, more even compression across the cylinders to reduced clearances in the crank mechanism and to longer intervals between overhauls. The verdict of the report, verbatim: "the effectiveness of XADO technology for repair and restoration of internal combustion engines without their disassembly, under normal operating conditions, has been experimentally proven". This concerns a diesel with 47 151 engine hours that had been in service for more than ten years: before treatment the commission recorded ultrasonic noise and knocking in cylinder 4, vibration and elevated oil burn-off consumption. The treatment was carried out on a running machine, the crane was not taken out of service; the commission recommended repeating it after 2000 engine hours.
The results relate to the six-cylinder diesel of a KATO F 399 DE truck crane with 47 151 engine hours; on other equipment and under other operating conditions the figures may differ. The treatment was performed by W.F.G. Corporation, whose representatives were members of the commission. The original report is published in full and available for download.
