“Gazel 983-93” engine: compression evened out without teardown, in service

Compression evened out across all cylinders, valve mechanism noise disappeared, oil consumption almost stopped. 0.2–0.5 kgf/cm² — compression in the cylinders, 8.5–9.0 → 9.0 kgf/cm² (2001).

Cylinder I was already at 9.0 kgf/cm² — after the treatment the other three came up to its level.

Conclusion of the test report

The engine entered the trial with uneven compression and noise in the valve mechanism. Compression physically cannot rise above the manufacturer's rated value, so bringing all four cylinders to 9.0 kgf/cm² is the limit achievable for this engine. ATP 11231 and Azurit LLC recorded the results in the test report and conclusion and recommended including planned preventive work using XADO technology® in the enterprise's scheduled vehicle repair system: 1. Compression evened out distinctly across all cylinders. 2. Noise in the valvetrain disappeared. 3. The fuel saving achieved amounted to 10%. 4. Oil burn-off consumption is close to zero. 5. Engine throttle response improved.

Application submitted by

Pilot treatment on the enterprise's equipment

  • any oil- or grease-lubricated assemblies: gearboxes, engines, compressors, bearings and others;
  • treatment within the regular operating cycle, without halting production;
  • instrumental measurements before and after: vibration, temperature, power consumption or current;
  • procedure for the specific assembly, dose calculation and support from a XADO engineer.

After the application, a XADO engineer will agree the units and the list of measurements with you.
