Depending on greenhouse gasses and clouds the level of outgoing radiation is approximately 3 km above the surface.
The port valve is therefore effectively timed to remain closed whenever the secondary carburetor throat is closed, isolating the induction tract from exhaust gasses.
Global warming is the effect of too many greenhouse gasses trapped in the air that hold in heat.
Further expansion of the gasses occurs in the propelling nozzle, where the gasses exhaust to atmospheric pressure.
Instead, they adjusted the flow of exhaust gasses to spool up instantly and provide strong power.
The hot gasses were then piped out of the combustion area into the power cylinder.
A steel laminate heatshield was installed on the bottom of the rear fuselage to protect it from the exhaust gasses.
There is also a bigger (2.7-inch) dual exhaust system that vents gasses out the back through the rear apron.
