The specified MCR (M) and its propeller curve 1 will normally be selected on the engine service curve 2.
Once point M has been selected in the layout diagram, the load diagram can be drawn, as shown in the figure, and hence the actual
load limitation lines of the diesel engine may be found by using the inclinations from the construction lines and the %figures stated.
