The engine was a 7:1 compression single Cyllinder engine with Sodium filled Exhaust valves. RPM was 2500.
Inlet Air was injected by some mechanism. They had the temperature fixed at 250F degrees for the last graph.
I should have shown THIS graph first, as this graph is the same procedure, but done at 150F degrees, which is more indicative of an intercooled engine.
Same colors as before ...
Enjoy.
