Has anyone ever made something that combined a springer and CO2?
Like … injecting CO2 into a springer’s chamber just as the trigger is pulled?

I've seen folks intentionally diesel their springers by putting a drop of 3 in 1 oil in the pellet skirt...

But isn’t CO2 used to extinguish fires? If so, might it actually suppress dieseling while simultaneously increasing chamber pressure?

Not sure what introducing CO2 to the mix would do. Not sure it would prevent detonation from compression, which is what dieseling is. I had only mentioned it because that was the only supplemental propellant I know of that has been used in tandem with springers...

I'm far from studied up on springer operation but my instinct is the CO2 would reduce velocity because its cooling effect would counteract the adiabatic heating of the springer's normal firing cycle, whereby reducing the pressure.

That could be. There must be a reason it hasn’t been tried.
My thinking is that a springer starts with air at 1 atmosphere and compresses it, but a shot of CO2 would raise the initial chamber pressure to well above 1 atmosphere

This is what happens when I have my morning tea . Brainstorming about a way to “supercharge” a simple springer without going all the way to PCP

I'd tend to think the added pressure wouldn't do anything but slow the shot down.
The Springs are designed for a given pressure. Toss in another 800 PSI and I'd suspect it would cushion the Spring.

That sounds right. The added pressure works in both directions … against the pellet and against the spring. So I guess the piston wouldn’t even move until it could overcome the chamber pressure, and by then the pellet has already left?

Hang on … what if we inject co2 *behind* the piston? Then it’s assisting the spring rather than fighting it. Methinks that would be like having a much stronger spring but without the added cocking effort

CO2 is liquid above about 900psi at 70°F. Injected in front of piston Co2 gas would revert to liquid under compression by the spring.
1) buy a more powerful airgun.
2) install a stronger spring
3) try adding a spacer under the spring to increase spring compression
All far less complicated and assure a more consistent result.

Your not taking port size into consideration.
A Strong Spring will not help much given port size, volume of chamber, and such.
So CO2 behind the piston? Just a worthless imitation of a stronger spring.
Not to even mention the redesign/manufacuring/cost of doing something like that.

Waiting to see who says
"But that CO2 would turn to gas pretty fast and add the power then."

Ok, it was a thought. Looks like there’s no advantage. I need to bounce these ideas off you guys, helps me understand what I’m missing

WRT a stronger spring, that sounds like the way to go. If a really powerful spring were installed it could pack quite a punch but also be too stiff to cock … perhaps a ratcheting mechanism on the lever could solve that, easier to cock but would require several pulls.

A stronger spring will yield more power but only to a point. An incremental gain as you are stuck with a fixed volume of air to compress, a fixed transfer port size and a pellet that’s going to start moving when a certain pressure is applied.
Better to buy a magnum springer if that is your performance goal rather than try to make one of lesser capabilities something it’s not.
