POWER OUTPUT
PERFORMANCE CURVES
Power curves are of standard test engines.
Power output will decrease 3.5 % for each 300m elevation increase above sea level and decrease 1 % for each
5.6°C increase above the standard temperature of 15.6°C.
As shipped, production engines will develop not less than 90 % of the "Maximum B.H.P."
After running-in, they will develop not less than 95 % of the "Maximum B.H.P."
For pratical operation, the B.H.P. load and engine speed should be within the limits defined by the
"Recommended maximum operating B.H.P." curve (below 90 % of the "Maximum B.H.P.)
For optimum engine service life in generator, pump and other continuous constant-load applications, operation
should be within 85 % of the "Maximum B.H.P."
* 80 % for GX(V) 610/620/670, for GC(V) 135/160 and for GCV/GXV 520/530.
Continuous operation with light load at low rpm is not economical. Such operation conditions can lead to
incomplete combustion of the fuel mixture, resulting in excessive exhaust smoke and carbon build-up.
Fuel consumption will increase under such operating conditions.
Running at low rpm limits the engine power and cooling performance of the fan and can cause engine
overheating and shortened engine service life.
With fluctuating loads (tillers, compressors, etc.) the engine should be run within the recommended maximum
operating B.H.P.
The engine speed setting must be chosen so that even if maximum load is suddenly applied, the engine speed
may not drop below the point where maximum torque is developed; this speed setting assures good
performance and fuel economy.
