Interesting Ideas for the future

Turbocharged ship diesels are getting over 50%, and compound generators have hit 60% without changing Carnot's equation. Still, I take most such claims with a block of salt.

Thanks guys for finding the links to that car..

I'm only a curious observer, watching and trying to learn.

Let me share the beer talk me and my friends have about
it. I don't know if I'm correct. Just speculation.

Well first, its a vapour system. The coils heat the fuel
but only fuel vapours go into the engine.

The carburator, we think, was only used to get the engine
up to speed. Once up to speed, the vehicle would just run
on vapor to maintain speed.

Here's some interesting speculation. They put the
motor in an insulated box to stop heat from escaping.

The actual engine ran much cooler than what we
see in our day to day commuting machines. We
think the engineers knew that if you lose heat then
you lose efficiency.

That's why rather than shedding unwanted heat by disposal
of it in the heat wastebin (radiator) these engines had no
such wastebin. They instead tried to preserve every piece
of heat they had and not any escape.

Vapour technology is interesting. I can't claim to be an
expert in it.

Now, that motor had no twin cams and was OHV. No VVTI,
or any of the things the brochures say we need today.

Of course, in reality it may have been on 30hp or less.

But it raises some very interesting questions.

Gasoline vapour will disperse into air faster than liquid, but that is not usually a big advantage, and might have defeated a CVCC lean-burn arrangement. "Running on fumes" is just a humorous exaggeration of using up the last of a tank.
Smokey Yunick tried hard to build adiabatic engines, but the materials and lubricants both broke down quickly. He had the best in the world, much better than those previously available. We still need cooling systems in addition to the exhaust to keep an engine healthy and prevent pre-ignition.

thats right.

The 376 mpg demo is interesting. I don't know of
other vapor conversions but I know many don't end
well.

My understanding of all the failures with implementations
of vapour injection is that the engine overheats because
there is no combustion chamber cooling system.

The 1900's might have the answer to that one and
what they did back then was use water injection instead
of liquid fuel to control the temperature in the combustion
chamber.

I'm very sure that water-injection can replace the
cooling ability of liquid fuel and control cylinder temperatures.

I personally do not care if I am using more water in my
car than petrol.

I'm thinking that maybe vapour might be good for idling
and coasting, and then if I need power, then allow the
fuel injectors to spray only when and if I actually need
some power.

Temperature control is vital. Actually the car I am using
has uses too much fuel and gets too hot. So all of this
thinking just comes with trying to fix the current problems

I want my car to run at 60% of its current temperature.

That's my goal. I'm told it will be more efficient.

not idling would be better yet.

What about engines that use cams in place of the crankshaft? Or, have some other format to covert the fuel to mechanical motion that is more efficient than the sinusoidal motion of a crankshaft?

[Big Dave]

Swashplate motors get away from the limitations of a crankshaft, but they are relatively high-friction mechanisms. Hard to lubricate.

You're going to change your view on this in few years.

Sure. One step at a time. I'm just a vapor hackmason..

[NeilBlanchard]

What about cams like the Revtec?
