IE B054REPORT UNDER CONTRACT No. 02/XADO OF 19.06.2001
ZIL-MMZ-45021 tipper: compression up in every cylinder, no teardown
Compression rose in every cylinder, idle fuel consumption decreased. 25–46 % — compression across the cylinders, 3.0–5.0 → 4.0–7.0 kgf/cm²; 2 min — running time on 1 l of petrol at idle, 16 → 18 min (Kazakhstan · 2001).

|---|---|---|
| ZIL-MMZ-45021 tipper truck,<br/>engine No. 080403 | built 1986, 15 years in service by the time of treatment; compression 4.8–5.0 kgf/cm², in cylinder 7 3.0 kgf/cm² | Compression across 8 cylinders; engine running time on 1 l of petrol at idle |
Compression by cylinder, engine No. 080403
| CYLINDER | BEFORE TREATMENT, KG/CM² | AFTER TREATMENT, KG/CM² | CHANGE |
|---|---|---|---|
| 1st | 4.9 | 6.5 | +33 % |
| 2nd | 4.9 | 7.0 | +43 % |
| 3rd | 4.9 | 7.0 | +43 % |

| 7th | 3.0 | 4.0 | +33 % |
| 8th | 4.8 | 6.5 | +35 % |
Each cylinder was measured before treatment and after 2736 km of running; the engine was not dismantled and the truck stayed in service.
Fuel consumption at idle
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Engine running time on 1 l of petrol | 16 min | 18 min |
