Toyota Camry 2AR in taxi service: compression evened out, fuel consumption dropped
Compression evened out across all cylinders, fuel consumption dropped, engine responsiveness improved. 27–40 % — cylinder compression, 10–11 → 14 kgf/cm²; 15.2 % — fuel consumption, 11.2 → 9.5 l (2018).

Key results
| 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.
