MAXIMUM OUTPUT
The maximum output of the EC02-A and ECOZ-R is such standard power as developed by the engine, after its 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 condi-
tion.
,"
2-2 CONTINUOUS RATED OUTPUT
The continuous rated output
of
the EC02-A and EC02-R
is
such power as developed by the engine when running at
an
opti-
mum speed most favorable in view
of
engine
life
and fuel consumption ratio. Therefore,
it
follows that when designing a driv-
ing system
for
any mechanism, with the engine, as a prime mover, the continuous power 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
the EC02-Aand EC02-R
is
that driving torque
of
the driving shaft at which the engine is driving an
external load, while the engine
is
pulling its rnax. output. The fuel consumption ratio at max. output
is
that fuel consump-
tion ratio
of
the engine while the engine is running at the max. output.
