You would expect the introduction of cooling into the I.C. Cycle would decrease thrust – this not what we see. Water injection gave Spitfires an extra burst of speed for short intervals. We are actually doing Molecular Nuclear Fusion
The ordinary I.C. Cycle also does a little Molecular Nuclear Fusion
When I was told diesel engines ran off water, I was doubtful. I cuts in at 10 amospheres – Fossil Fuels diesels run at a minimum of 8.
But we get more power at higher pressure, so it is likely we have already got commercially available diesels, that run off water.
So this is work a garage can confirm. Then we need to pump liquid water around an Al coil of the exhaust, to get steam.
To start the cycle off, we need to charge up a steam reservoir. Then we get a diesel which runs off water.
No micro particulates, and as mush NOx as a petrol engine. This science was worked out in World War II. You can buy retro fitted water injection systems for sports cars today. Ash surviving Spitfire pilots about water injection – a system so violent, you had to do an engine re-build.
We can alter a production car, to run off just water. We may choose to keep Fossil Fuels burning, to start the system off. Then change over to water.
And we produce carbon 0 cars – that 'burn' water. See 1. Modern materials can cope with Molecular Nuclear Fusion – no problem. Line the cylinders with TiO ceramic – t odouble the engine power. We are already looking at a 20 fold increase in engine power.
