Robin EY08D - 2. PERFORMANCE; 2-1 MAXIMUM OUTPUT; 2-2 CONTINUOUS RATED OUTPUT; 2-3 MAXIMUM TORQUE and FUEL CONSUMPTION RATIO at MAXIMUM OUTPUT

2. PERFORMANCE
2-1 MAXIMUM OUTPUT
The maximum output of an engine is such standard power as developed by the engine, after its initial break-in
period with all the moving parts properly worn in, when operating with a fully open throttle valve, Therefore,
a new engine may not develop the maximum output in the beginning because the moving parts are not in a
properly worn-in condition.
2-2 CONTINUOUS RATED OUTPUT
The continuous rated output of an engine is such power as developed by that engine when running continu-
ously at an optimum speed, and most favorable from the viewpoint of engine life and fuel consumption ratio,
with the governor in operation. It is suggested, therefore, that when designing a driving system
for any mech-
anism, with this engine
as prime mover, the continuous power requirement of that mechanism be kept below
the continuous rated output specified.
2-3 MAXIMUM TORQUE and FUEL CONSUMPTION RATIO at MAXIMUM OUTPUT
These mean the maximum torque of the output shaft and fuel consumption ratio at the maxiumum output
of
an engine.
