10D100 and 12VFE diesels: compression up, fuel consumption down
Compression rose in all cylinders of both diesels, idle fuel consumption and noise dropped. 13–72 % — cylinder compression, 25–28 → 27–31 and 18–20 → 31–35 kgf/cm²; 14.5–25 % — fuel consumption at idle, 108 → 81 l/h on the D1 diesel train; 8–17 dBA — noise level at maximum speed, 131 → 114 and 108 → 95 dBA (2003).

Cylinder compression — both diesels, two mileage checkpoints
| DIESEL · MILEAGE AFTER TREATMENT | BEFORE TREATMENT | AFTER | CHANGE |
|---|---|---|---|
| 10D100 No. 1432FKh · 29 864 km | 25–28 kgf/cm² | 27–31 kgf/cm² | +12.8 % |
| 10D100 No. 1432FKh · 114 014 km | 25–28 kgf/cm² | 28–30.5 kgf/cm² | +13.4 % |
| 12VFE 17/24 No. 24282 · 41 136 km | 18–20 kgf/cm² | 31–33 kgf/cm² | +61.9 % |
| 12VFE 17/24 No. 24282 · 115 675 km | 18–20 kgf/cm² | 32–35 kgf/cm² | +72.0 % |
Depot compression gauges, GOST 2405-80. The gain is the greater the lower the compression was before treatment; growth was recorded in every measured cylinder of both diesels.
Fuel consumption at idle
| DIESEL | AFTER 30-41 THOUSAND KM | AFTER 114-116 THOUSAND KM |
|---|---|---|
| Locomotive 2TE10UT No. 0036 · 10D100 diesel | −14.5 % | −19.8 % |
| Diesel train D1 No. 764 · 12VFE 17/24 diesel | −21.3 % · 108 → 85 l/h | −25.0 % · 108 → 81 l/h |
Measured at idle with the depot's standard instruments. On each diesel the saving at the second measurement was deeper than at the first.
Noise level at maximum speed
| DIESEL · MILEAGE AFTER TREATMENT | BEFORE TREATMENT | AFTER | CHANGE |
|---|---|---|---|
| 10D100 No. 1432FKh · 29 864 km | 131 dBA | 123 dBA | −8 dBA |
| 10D100 No. 1432FKh · 114 014 km | 131 dBA | 114 dBA | −17 dBA |
| 12VFE 17/24 No. 24282 · 41 136 km | 108 dBA | 96 dBA | −12 dBA |
| 12VFE 17/24 No. 24282 · 115 675 km | 108 dBA | 95 dBA | −13 dBA |
Depot sound level meter, measured at the maximum operating speed of each diesel.
Power output, combustion pressure and oil pressure
| DIESEL · PARAMETER | BEFORE TREATMENT | AFTER | CHANGE |
|---|---|---|---|
| 10D100 · power on the rheostatic test bench, 850 rpm | 1780 kW | 1850 kW | +3.9 % |
| 12VFE 17/24 · maximum combustion pressure, 1180 rpm | 40 kgf/cm² | 59–63 kgf/cm² | +52.9 % |
| 12VFE 17/24 · oil pressure, 830 rpm | 2.8 kgf/cm² | 3.4 kgf/cm² | +21.4 % |
The locomotive diesel power was taken on the depot's rheostatic test bench; the gain holds even after 114 014 km of mileage.
