Measurement before the restorative repair with XADO technology and a repeat measurement after the control run; both measurements were made in the presence of the head of the repair shops and the senior foreman of the company.
Conclusion from the two reports
Both reports of ATP Khabarovskenergo JSC were signed on the same day and describe the same job on different vehicles: restorative engine repair with XADO technology without disassembly, a compression measurement before treatment and a repeat one after a control run. On the MITSUBISHI CHALLENGER compression rose by 12.0-16.7 % on every cylinder measured, on the TOYOTA LAND CRUISER by 6.9-10.0 %; on no cylinder did it fall. The gain was obtained on two different engines with different compression levels and was confirmed not on the day of treatment but after 1500 and 3000 km of normal service: the restored sealing of the cylinder-piston group holds up in service. Compression is capped from above by the manufacturer's rated value — the growth runs towards it and stops there, which is why the score here is in percent, not in multiples. The measurements were made in the presence of company officials, and both reports carry a stamp.
The results apply to the engines of the listed SUVs from the fleet of ATP Khabarovskenergo JSC and to their operating conditions; on other vehicles and duty cycles the figures may differ. The originals of both reports, with signatures and stamps, are published in full and available for download.
