Increasing the load of a warmed-up engine (generator engine)
The load can only be increased depending on the continuous power P
me
according to the values
recommended by DIN 6280 and ISO 3046. The graph below shows the possible load stages at which
the frequency settling time stipulated by DIN/ISO is possible.
The diagram shows guide values for load stages in % engine rating depending on the mean
effective piston pressure of rated output, on the example of a 6 M20-engine with a full load
p

= 21.9 bar.
