I should explain to others how to read it:

The top graph shows the torque of the engine ( a Series 60 - 3), it shows peak torque at 1500rpm, then it drops off big heaps, interestingly the peak toque happens at 1200 rpm.

The middle graph is the horsepower of the engine, it climbs to a peak at 1670rpm, then drops off.

The bottom graph is fuel consumption under load, it's best reading for fuel useage is at 1500 rpm.

So what does this mean, it means that you souldn't take this engine over 1700rpm because you loose torque, horsepower and you will start to use more fuel, and your lower end should be 1200 to pick up the bes tof your available torque.

Ahh, the beauty of modern electronic diesel engines!!!
