Key results

↑8%

compression across the cylinders, 7.5-8.0 → 8.0-9.0 atm

↓43-50%

exhaust toxicity, CO 6.58 → 3.75 % and CH 375 → 187 ppm

MACHINE AND UNIT	MILEAGE AT TEST START	WHAT WAS MEASURED
UAZ-69, reg. no. RV 1344 VV — engine, 4 cylinders	126,000 km	Compression in each of the four cylinders; CO and CH in the exhaust gases
Same vehicle — gearbox	126,000 km	In-service assessment: noise, gear engagement

Engine compression by cylinder

CYLINDER	BEFORE TREATMENT, ATM	AFTER, ATM	GAIN, ATM
I	7.5	8.0	+0.5
II	7.5	8.0	+0.5
III	8.0	9.0	+1.0
IV	8.0	9.0	+1.0

Compression rose in all four cylinders. The gain is capped by the engine's factory nominal: compression cannot rise above it.

Exhaust gas toxicity

PARAMETER	BEFORE TREATMENT	AFTER	CHANGE
CO, % in exhaust	6.58 %	3.75 %	−43 %
CH, ppm	375 ppm	187 ppm	−50 %

The exhaust gas measurement was carried out and certified with its own stamp by an outside contractor — "FORD" auto service, B. Yordanov.

Protocol conclusions

The commission of Elektrorazpredelenie EAD, Plovdiv, together with "MAY" OOD recorded the following results of the treatment by XADO technology: 1. Compression in the cylinders increased by 8 % on average. 2. Emission of toxic substances in the exhaust dropped by 43 – 50 %. 3. Gearbox performance improved: the noise in operation disappeared, the gears became easier to engage. The vehicle came to the treatment with 126,000 km on the odometer, and after only 2,680 km of normal service the compression had risen in all four cylinders, while the CO and CH content in the exhaust gases fell roughly by half. The engine and the gearbox were neither disassembled nor repaired: the result was obtained on machinery that kept working every day.

The results relate to the petrol engine and the gearbox of a UAZ-69 vehicle with 126,000 km on the odometer, operated by Elektrorazpredelenie EAD, Plovdiv; on other machinery and under other duty cycles the figures may differ.
