1. Foreword
1.1. Units of pressure
1.1.1 - Units of pressure in bars.
N.B. : One bar has the advantage of being close to the average atmospheric pressure at sea level.
1.1.2 - Unit of pressure in millimetres of mercury (symbol: mmHg) or Torr (symbol: Torr).
This unit of measurement of pressure was origially defined as the pressure exerted at 0°C by a 1 millimetre column of mercury, later indexed to the atmospheric pressure.
The pressure values indicated in the tables below are the values read on the pressure gauge (Relative pressure).
N.B. : Relative pressure is equal to absolute pressure minus atmospheric pressure.
1.2. Units of tension
The SEEM unit measures by deflection of the static tension of the belt, by deforming a portion of its length.

10. Pressure, engine end of compression / Cylinder leakage rates
10.1. Pressure, engine end of compression
Measure the pressure at the end of compression, in order, on cylinders 1, 2 and 3.
Description | Minimal value | Nominal value |
End of compression pressure | 9 ± 0,3 bars | 12 ± 0,3 bars |
N.B. : The difference in pressure between 2 cylinders must not exceed 3 bars.
CAUTION : Always search for the origins of fault(s), where the values measured are found to be significantly out.
10.2. Cylinder leakage rates
Cylinder leakage rates are considered non-compliant if they are higher than the following values.
Measuring of the leak rate of the cylinders
Km (mileage) | Less than 30000 kilometres | 30000 to 100000 kilometres | More than 100000 kilometres |
Leakage rate | 10% | 12% | 16% |
