IE S008FOUR TEST REPORTS · MARCH — MAY 2006
Drill rig diesels: UBSh-312A, BOOMER, AXERA — compression gain repeated
Compression rose in all measured cylinders, the spread across cylinders closed up, fuel consumption dropped. 20–33 % — compression across cylinders, 15.5–33 → 27–40 kgf/cm²; 0.26 l/h — idle fuel consumption, 1.58 → 1.32 l/h (2006).

Cylinder compression — four rigs
| RIG | BEFORE TREATMENT, KGF/CM² | AFTER, KGF/CM² | GAIN, KGF/CM² | GAIN, % |
|---|---|---|---|---|
| BOOMER 251 No. 1, Deutz F4L912W | 29.0–33.0 | 37.5–39.5 | 6.5–8.5 | 20–29 |
| AXERA D05 No. 2, Deutz F4L912W | 31.0–32.0 | 37.0–40.0 | 5.0–9.0 | 16–29 |
| UBSh-312A No. 14, D243 | 15.5–22.1 | 27.0–29.5 | 7.4–13.5 | 34–87 |
| UBSh-312A No. 18, D243 | 22.0–23.0 | 27.0–29.0 | 4.2–6.0 | 18–27 |
Each cylinder was measured with a ZECA 363 diesel compression tester — before treatment and after the operating period. A gain was recorded on every cylinder measured on all four rigs.
Fuel consumption — AXERA D05 No. 2, fuel system
| PARAMETER | BEFORE TREATMENT | AFTER | CHANGE |
|---|---|---|---|
| Running time on 100 ml of fuel, idle | 3 min 48 s | 4 min 32 s | +44 s |
| Fuel consumption, idle | 1.58 l/h | 1.32 l/h | −0.26 l/h |
Measured with a stopwatch on a fixed fuel volume before treatment and after 54 engine hours. The fuel system was treated on all four rigs.
