2-1MAXIMUMOUTPUT

The maximum output of an engine is such standard power as developed by that engine, after its initial run-in period witha1

themovingpartsproperlyworn-in,whenoperatingwiththefullyopenthrottlevalve. Therefore,itfollowsthat a nev

enginemaynotdevelopthismaximumoutputinthebeginning,becausemovingpartsarenotin aproperly w0rn-hcondition.

2-2 CONTINUOUSRATEDOUTPUT
The continuous rated output of an engine is such power as developed by that engine when running at an optimum	speec

most favorable from the point of view of engine life and fuel consumption ratio. Therefore, it follows that when designing i

driving systemforanymechanism,withamodel EY33-2or EY44-2engine, as a primemover,thecontinuouspowe requirement of that mechanism must be kept below the continuous rated output specified.

2-3MAXIMUMTORQUEANDFUEL CONSUMPTION RATIOATMAX.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 o an engine while that engine is running at the max. output.
