Measuring Combustion Pressure in Cylinders
Appendix 5 sets out the procedure for measuring combustion pressure in the cylinders of locomotive and marine diesel engines by means of a maximeter connected through an indicator cock. Measurements are taken on a warmed-up engine under load, cylinder by cylinder.
Procedure for Measuring Combustion Pressure in the Cylinders of Locomotive and Marine Diesel Engines
Procedure
- Warm up the engine to its operating temperature.
- Set the engine speed at which maximum power is reached and apply a load to the engine.
- Connect the maximeter to the engine cylinder through a special indicator cock.If the cylinder has no indicator cock, one must be installed with the engine shut down.
- Open the cylinder indicator cock, close the maximeter valve and record the maximum pressure gauge reading.
- Open the maximeter valve, close the cylinder indicator cock and disconnect the maximeter.
- Measure the combustion pressure in the remaining cylinders in the same way.
