Looking for help building a Gas Vapor system

[teoman]

400 deg C is 752 deg F. What they are using.

I would heat some fuel in an injector and see for yourself how it performs. If it acts like a flamethrower you can maybe fill a clear container with exhaust or argon or nitrogen and observe what the transonic guys are doing. Then you can try it in the air. Your injectors will not work for long but i guesstimate it will be long enough for you to see. Then you can have a look at cooling the same vapor. Maybe attaching the injector to a copper pipe (that is heat controlled or just running through boiling water) to see if you can get vapor out or if you get condensation of your sludge once the fuel cools down.

Yes, and i am describing a method how you can test your theory that when it cools down the "gunk" will not recondense.

If the injector does not survive, you can try injector to heated copper pipe to teflon tube to cooled copper pipe.

Have it first shoot in to a bucket of water or exhaust gas bag untill the o2 in the system is consumed/ejected then you could try it in the air.

If successfull you have a precisely metered vapor injection system with a bit of delay. After this you can try adjusting the hot zone length and cold zone length.

To heat it up intially, you can place a kiln heating element close to the copper pipe and then embed the lot in plaster of paris, or wrap it in several layers of "titanium exhaust wrap". I think it was lava rock wool or some such thing.

That is what i am proposing. An injector to have a precise control of fuel flow. Followed by a hot copper pipe followed by a cooling copper pipe, just as you are proposing. You can add teflon tubing in between to act as heat barriers so hot part of pipe does not contact cold part (or even between the injector). With such a simple system you can test your ideas.

Once the vapor cools down (as you propose) we do not know if the gunk will condemse out, with this setup you can test that.

They mean little to you because you don't understand the basics of industrial chemistry and thermochemistry. You admitted you know nothing about rate equations. That is high school chemistry. How do I speak about the ins and outs of thermochemistry when you can't even begin to understand such basics?

Don't blame me for your lack of education.

The EGR through a bubbler of gasoline is a safe and useful first test. It is a basis for the GEET. I have seen GEETs in action and seen their severe limitations but do see some value. The use of EGR allows a hot gas addition to vaporize your fuel without the chance of your heated gasoline/air mix spontaneously oxidizing. THAT is the advantage of EGR use in a stoichiometric run regime. Once mixed in with air, it burns normally.

Your fuel heater/condenser will still have issues with gunk dropping out of the vapor stream. And you do know about thermal depolymerization and reformation of hydrocarbons in a subcritical heated hydrocarbon fuel solution? It isn't just gunk that is in your gasoline that will clog and destroy your systems operation. Once you heat your fuel, you will find other compounds forming dependent on the interactions with your materials of construction. I've been there and done that. You are walking blindly into it.
