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.

Conclusions of the depot commissions

The commissions of the T. G. Shevchenko locomotive depot measured the parameters of each diesel twice — at scheduled repairs after 30-41 thousand km and after 114-116 thousand km of mileage. Compression grew in every measured cylinder of both engines, fuel consumption at idle fell in all four measurements, and by the second measurement the effect had become deeper, not weaker. The diesel of locomotive 2TE10UT had run eleven years without overhaul by the time of treatment; the document of 18.09.2003 records: «after a mileage of 114014 km no deterioration of the engine's operating parameters occurred, which in fact indicates the absence of engine part wear». The passport for the D1 diesel train concludes that the measurements «confirm the stability of the results obtained after treatment under the XADO technology over a long period of operation».

The results relate to the 10D100 and 12VFE 17/24 locomotive diesels under the operating conditions of the T. G. Shevchenko depot of the Odesa Railway; on other engines and duty cycles the figures may differ. The original passports with signatures and stamps are published in full and available for download.
