PERFORMANCE

2-1 MAXIMUM OUTPUT

The maximumoutput

the output

an engine with its throttle valve fully opened under the

condition

that all the moving parts are properly worn in after the initial break-in period.

new engine may not produce full maximum output while

its

moving parts are

still

not broken-in.

2-2 CONTINUOUS

RATED

OUTPUT

Thecontinuous rated output is theoutput ofan engine at optimum governedspeedwhich is

most

favorable

from

the view point of engine’s life and fuel consumption.

When the engine

installed on acertainequipment,

recommended that thecontinuousoutput

required from the engine bekept below

this

continuous rated output.

2-3MAXIMUM TORQUE

The maximum torque

the

torque

the output shaft when the engine

producing maximum output at

certainrevolution.
