Good effort, taking all that time to do this.
Can I just, again reiterate:
And saying planes will produce more particles through richer mixtures is just a true statement.
For a piston engine, this is true. It involves the fuel/air ratios, and anyone with a passing knowledge of auto mechanics understand this.
Modern jet turbine engines, however...operate differently. In simplest terms, to make a fuel/air mixture more 'rich', you increase the ratio of
fuel, to the amount of air. Turbine engines, though, get their air from the environment...it is readily available, and free for the taking, right in
from the front (the intake). The air is not metered, nor managed by a 'carburetor' or even restricted and modulated, as in a fuel-injected piston
A turbine engine, when you increase the flow of fuel (the rate and amount), it will simply 'find' the air it needs in order to provide
combustion....this generates more heat, and power. But, there is an upper limit regarding heat, and thus..power output has a limitation too.
The increase in power, besides making it hotter, also increases the RPM of the components, and they also are limited, based on design and material
strengths and tolerances.
The only way to make the jet turbine exhaust 'dirtier' or 'smokier' is to revert to older technology designs....or, out of the range of
feasibility, use a process called 'water-injection' (actually, a 50/50 water/isopropyl alcohol blend) which cools down the gases, as they exit the
combustion chamber, so the turbine blades and rotors don't experience the excessive heat....this provides a brief time of extra power 'boost'.
But, of course, takes a lot of the water mix...and, this equipment is more trouble than it's worth, and isn't practical except in limited
