• When the load on the pump rises and the pres-
sure rises, the engine speed goes down.
At this time, the pump discharge is reduced and
the engine speed is set about the rated output
point. If the pressure lowers, the pump dis-
charge is increased until the engine speed is set
about the rated output point.
By repeating this control, the engine can always
be used at near the rated output point.
• Compared with the A mode, which provides the
maximum output, the E mode lowers the engine
output to provide matching at a point which gives
better fuel consumption efficiency than the A
mode.
