Hi Tommey,
I engineered it in this way:
I used following concept, it is a very old concept you even could buy in the 70s. There was a plastic rocket which you filled up with a little bit of water and than you pumped it up.
Without the water the rocket did not lift...but with the little bit of water it was shot to the sky.
Same effect using a empty water hose at your house...you open the focet of the empty pipe only a little bit and at the end of the hose the water comes out as a explosion.
Translatet to a wheel with small, round, conic water channels you need allways to inject water-air-water-air.
By turning the wheel water presses the air and the air presses the water out of the jets.
Important is that the channels should be small in diameter, starting about 8mm diameter going to 4mm diameter.
My engine using a timing of two injections at same time, at 12 o´clok and 6 o´clock.
So only in this position the channels are getting water in.
With an adjustable timing I could adjust more or less water injection.
Air is added by special drilled holes at the center of the wheel. holes work as a walve without need to close the holes.
Centrifugal force of the wheel will manage that no oil comes out of the air holes.
My system should run by itself at a speed of about 1900rpm.
I will take some pictures of the device which had been professional built by a construction company.
My device had some issues as square not conic channels, so it was only one time running super shortly by itself and even did not work by trying to get it running again.
extremly complicated to adjust air, water, RPM, Waterpressure. And important to use oil instead of water. I run it on a nice place...so was not possible to use oil...
You only need to watch the time when it was engineered, it was the rocket time and even at scool they teached the water rocket effect..and you could buy the rockets as children toys.
I am very sure that this simple construction should work, but it will be not a easy job as only a single parameter needs to be wrong.
We should need a hydraulic engineer to prevent mistakes...

my thougts....when you make a combustion before the liquid is entering the channels it could not create the pressure which is neccessary at the jets and it could not selfrunning...
