Why not an engine-heated fuel injection system?

block without oxygen. This would heat up the liquid to more than one
pressure, I'm sure. Also, a car engine operates at very high
temperatures, often much more than 212 F. Let's assume that it works
at 250 F.
I would think that allowing the gasoline to heat up without oxygen to
prevent combustion and eject inside the pistons at 2 atmosphere
pressure is a natural fuel injector, with perfectly atomized fuel.
What's wrong with this idea? The only thing bad that I can think of
is that the gas would rapidly expand inside the piston and partially
condense, perhaps, which may offset my "perfectly atomized fuel
charger idea".

Leak->explosive fire->death (plus excessive expansion of moving parts,
a minor secondary consideration). Car engines operate at much lower
temperatures than 212F, they use water as a coolant. That's what is wrong.

Bad assumption; the temperatures inside an engine are far higher then
that.

Most fuels boil at relatively low temperatures.
Ever heard of the term "vapor lock"?
How do you get 2 atmosphere pressure on the intake stroke where the pressure
is usually local atmospheric?
Getting 2 atmospheres would require one hell of a turbocharger, roughly
doubling the fuel flow to keep the mixture correct, and likely would result
in either a melt down of the engine or seizure from things spot welding.

Well, for starters, the fuel expands in the cylinder, not the piston,
and the vaporization of the fuel helps keep the temperature inside the
cylinder down so it doesn't melt.
Other than those few minor nits, why don't you try it on your car and get
back to us.

reach temperatures of 120 or more in the summer.
You get a condition called "vapor lock".
Actually they try to *cool* the fuel lines in these areas! (To prevent vapor
lock.)

It will pyrolyze, depositing varnish and char, and generating
particulates that clog conduits and form soot in combustion chambers.

Wow. I can has engineering?

Are ya gonna heat the gas tank, too?
A four-stroke auto engine has a compression ratio of about 8:1. Maybe
you should look up carburators and fuel injectors plus the engineering
of an efficient, nonpolluting engine and learn something about how it
all works.

You want the charge - air and fuel - to go in as cold as possible.
Look up why or learn some thermodynamics.

A few years back, I saw an Audi caught on fire in front of my house while it
was parked for 30 minutes. I believe German cars already heat up gasoline to a
certain degree, heat can rise up and cause explosion even when you leave it in
park position.
If you want to improve your car fuel economy, why not using this device?

It's supposed to save fuel by as much as 1/2, the top model saves even more.
It's risky if over-heating gasoline above a safe point while on the road...
