PMI System
As an option on the MC engines, the mechanical
indicator system can be supported by a pressure
analyser system for measurement of the cylinder
combustion pressure.
Monitoring of cylinder pressures allows for:
• optimising the engine performance
• optimising the fuel economy
• minimising engine load
• minimising operating cost through condition
based maintenance
• complying with emission requirements
Measurements
The cylinder pressure is measured by a high
performance piezo-electric pressure transducer,
mounted on the indicator valve.
The engine speed signal is obtained from an an-
gle encoder mounted on the crankshaft fore end.
Alternatively the signal could be obtained from a
trigger arrangement on the aft end of the engine.
The PMI system compensates automatically for
the twisting experienced by each section of the
crankshaft due to the torque generated at differ-
ent loads.
