KamAZ and ZIL-130: higher compression and fuel savings instead of overhaul
Compression in the cylinders rose, most in the most worn one, fuel consumption decreased. 3.7–10.8 % — compression in the ZIL-130 cylinders, 6.5–8.9 → 7.2–9.5 kgf/cm²; gain in 3 of 4 readings; the rest unchanged; 11.5–13.5 % — fuel consumption of both trucks, 100 ml burned in 45 → 52 and 100 → 113 s (1999).

Key results
| VEHICLE | MILEAGE AT START | WHAT WAS MEASURED |
|---|---|---|
| KamAZ dump truck, reg. No. 1652 YaN1 | 76,443 km | Fuel consumption, oil pressure |
| ZIL-130, reg. No. 78-79 YaNA | 49,426 km | Compression by cylinder, fuel consumption, oil pressure |
ZIL-130 — compression by cylinder
| CYLINDER | BEFORE, kgf/cm² | AFTER, kgf/cm² | GAIN |
|---|---|---|---|
| Cylinder 2 | 8.2 | 8.5 | +0.3 · +3.7 % |
| Cylinder 3 | 8.9 | 9.5 | +0.6 · +6.7 % |
| Cylinder 4 | 8.6 | 8.6 | no change |
| Cylinder 6 | 6.5 | 7.2 | +0.7 · +10.8 % |
Compression is capped by the engine's rated value, so the largest gain came from the most worn cylinder: 6.5 → 7.2 kgf/cm².
Fuel consumption and oil pressure — both trucks
| PARAMETER | KAMAZ, BEFORE → AFTER | ZIL-130, BEFORE → AFTER | CHANGE |
|---|---|---|---|
| Time to burn 100 ml of fuel, s | 45 → 52 | 100 → 113 | consumption −13.5 % · −11.5 % |
| Oil pressure, kgf/cm² | 3 → 3.5 | 1 → 1.7 | +0.5 · +0.7 |
| Coolant temperature, °C | 60 → 60 | 60 → 60 | thermal conditions of the readings identical |
Fuel consumption is inverse to the time taken to burn the control portion: the longer it lasts, the more economical the engine.

About this result:
Limits of this report: The results refer to the engines of the KamAZ dump truck and the ZIL-130 of the motor transport shop of STIROL Concern OJSC; on other equipment and under other operating conditions the figures may differ. RVS is an obsolete XADO designation, the zero-generation formulations; the current product generation is revitalizants.
