IE B041COMMISSION REPORT, KAZZINC JSC, MAY 2002
KATO F 399 DE truck crane: quieter, smoother diesel no teardown, no downtime
Knocking and vibration disappeared, oil pressure rose, the cylinders began running cooler. 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 (2002).

Key results
| 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.

Limits of this report: 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.
