PMI System, Type PT/S Offline
On the MEengines, the mechanical indicator sys-
tem is replaced by a Pressure Analyser System
for measurement of the cylinder combustion pres-
sure.
The PMI pressure analyser systems measures the
engine’s main parameters, such as cylinder pres-
sure, scavenge air pressure, engine speed etc.
enabling the engineer to run the diesel engine at
its optimum performance.
This system gets its data from a high performance
piezoelectric pressure transducer which is to be
mounted on the indicator valve. The transducer
is moved from one cylinder to another in order to
complete measurements on all cylinders.
The crankshaft position is determined by means
of the same trigger system as for the engine con-
trol system.
The PMI system compensates automatically for
the twisting experienced by each section of the
crankshaft due to the torque generated at differ-
ent loads.
