Foreword
Units of pressure
1/ units of pressure in bars
NoteOne bar has the advantage of being close to the average atmospheric pressure at sea level
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)
NoteRelative pressure is equal to absolute pressure minus atmospheric pressure
Units of tension
The SEEM unit measures by deflection of the static tension of the belt, by deforming a portion of its length

Pressure, engine end of compression
Measure the pressure at the end of compression, in order, on cylinders 1, 2,3 and 4
NoteThe difference in pressure between 2 cylinders must not exceed 5 bars
WarningAlways search for the origins of fault(s), where the values measured are found to be significantly out
