Torque Gauge
The engine torque output
is measured by measuring the torque that is supplied to stop the rotation
of the outer case of the Generator. The generator and the engine are in
mechanical equilibrium and these two quantities have the same magnitude (but
opposite sign).
The torque reading is obtained in two ways: (i) A strain
gauge balance on an arm of known mechanical properties is used to provide
torque information to the computer data acquisition system; (ii) A pressure
capsule is deflected by the strain gauge balance arm and this pressure is
displayed by the dynamometer torque gauge.
Torque and RPM information
is to be used co compute the output work of the transparent engine when it
is running in steady state. This work should be compared to that obtained
from the (p,v) curve for the working fluid in the engine. |
