Fuel Injector Balance Test Example
| Cylinder | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| First Reading | 360 kPa (52 psi) | 360 kPa (52 psi) | 360 kPa (52 psi) | 360 kPa (52 psi) | 360 kPa (52 psi) | 360 kPa (52 psi) |
| Second Reading | 195 kPa (28 psi) | 138 kPa (20 psi) | 195 kPa (28 psi) | 195 kPa (28 psi) | 235 kPa (34 psi) | 195 kPa (28 psi) |
