Key results
↑27-40%
cylinder compression, 10-11 → 14 kgf/cm²
↓15.2%
fuel consumption, 11.2 → 9.5 l
| EQUIPMENT | CONDITION AT START OF WORK | WHAT WAS MEASURED |
|---|---|---|
| Toyota Camry, 2012<br/>2AR engine, 2.5 l | Six years of taxi service<br/>compression 10-11 kgf/cm² | Compression in all four cylinders · fuel consumption |
Compression across the cylinders of the 2AR engine
| CYLINDER | BEFORE TREATMENT, kgf/cm² | AFTER TREATMENT, kgf/cm² | CHANGE |
|---|---|---|---|
| I | 10 | 14 | +4 kgf/cm² · +40 % |
| II | 10 | 14 | +4 kgf/cm² · +40 % |
| III | 10 | 14 | +4 kgf/cm² · +40 % |
| IV | 11 | 14 | +3 kgf/cm² · +27.3 % |
| Spread between cylinders | 1 kgf/cm² | 0 kgf/cm² | All four cylinders at the same value |
Compression does not rise above the nominal value set by the engine manufacturer: bringing all four cylinders to a single value is the maximum achievable.
Fuel consumption
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT | CHANGE |
|---|---|---|---|
| Fuel consumption | 11.2 l | 9.5 l | −1.7 l · 15.2 % |
The drop in consumption follows from the restored sealing of the cylinder-piston group: even compression across all cylinders gives even engine running.
What the act recorded
The treatment was performed without disassembling the engine, on a car that had by then worked six years in taxi service. In the section «Results of treatment» the act states: «Compression evened out across all cylinders» and «Engine throttle response improved». The measurements confirm this: all four cylinders moved from 10-11 to a single value of 14 kgf/cm², fuel consumption 11.2 → 9.5 l. Compression cannot rise above the factory nominal value, so an identical reading in every cylinder is the maximum achievable for a worn engine, and even cylinder operation is exactly what produces the fuel saving. The act recommends: «Introduce into the system scheduled preventive maintenance of machines and mechanisms using XADO technology, ensuring an increase in service life», and XADO technology is recommended for use at Taxi Moy Gorod LLC.
The results apply to a Toyota Camry passenger car with a 2.5 l 2AR petrol engine in taxi operation; on other engines and operating modes the figures may differ. The original act of conclusion dated 20.08.2018, with signatures and stamps, is published in full and available for download.
