I thought the resulting effective C/R of the standard increase to 1.0bar on a 7.0:1 930 engine interesting because it falls nicely within what is considered a safe zone on your graph.
The operating environment for any vehicle can be very wide, from well below freezing to well above 100F at varying elevations. Having this graphed or mathematical information is necessary to make decisions of how far you can push your engine parameters given the environment it will operate.
