2. PERFORMANCE
2-1 MAXIMUM OUTPUT
The maximum output of an engine is such standard power as developed by that engine, after its initial run-in period with all
the moving parts properly worn-in, when operating with the fully open throttle valve. Therefore, it follows that a new
engine may not develop this maximum output in the beginning, because 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 at an optimum speed
most favorable from the point of view of engine life and fuel consumption ratio. Therefore, it follows that when designing a
driving system
for
any mechanism, with a model EC05-2,07-2, IO, 17
or 25-2
engine, as a prime mover, the continuous pow-
er requirement of that mechanism must be kept below the continuous rated output specified.
2-3 MAXIMUM TORQUE and FUEL CONSUMPTION RATIO AT MAX. OUTPUT
The maximum torque of an engine is that driving torque of the driving shaft at which the engine is driving an external load,
while the engine is developing its max. output. The fuel consumption ratio at max. output is that fuel consumption ratio of
an engine while that engine is running at the max. output.
