That's a close enough idea of how the HyCO 2DT works. Please know that the HyCO 2DT and the HyCO 2A, while both are 'evaporitive fuel' technologies, are different devices. The HyCO 2DT is designed to work on turbocharged (diesel or gasoline) engines. The HyCO 2A only works on gasoline engines.

I'd change the word 'huge' to 'respectable'; and note that any gains are only acquired if everything is working correctly (which I assist anyone I can).

The HyCO 2DT regulates fuel vapors using turbo pressure. As the engine comes under load, the turbo pressure increases and 'more' vapors are formed.
The HyCO 2A generally depends on engine vacuum so reduces it's vapor as the engine comes under load... Unless you put a venturi in the intake air, then the vapors will pretty much match air consumption.

Yes, so you answered your own question. It doesn't matter if you are burning gasoline in liquid or vapor; as you increase combustion efficiency your exhaust oxygen content will rise.

Those are good questions which become really obvious once you start using the technology. You cut back on the liquid as you add vapor, so the air:vapor fuel ratio stays consistent (which is why you don't lose power). I can't tell you how much vapor is produced because there are too many variables.
With diesel, the HyCO 2DT doesn't produce enough to have a combustible mixture in the intake manifold, but it will for gasoline.
The HyCO 2A will produce enough vapors to idle a 300 ci engine but I don't recommend producing that much, it makes it harder to make a smooth transition between the vapor and liquid fuel systems.

No. That is a common misunderstanding. The EFIE is NOT a fuel saver, ask anyone who has installed it without also installing an actual combustion enhancement technology.

It is as safe or safer that the vehicle's fuel tank. In hundreds of installations over decades of time, on all kinds of vehicles, I've never heard of a mishap.
