Racprops....if the engine is 98% efficient at burning gasoline, pray tell, how does converting it to vapor and burning it just the same improve things?

[B]OK Read this:

Modern gasoline engines have a maximum thermal efficiency of about 25% to 30% when used to power a car. In other words, even when the engine is operating at its point of maximum thermal efficiency, of the total heat energy released by the gasoline consumed, about 70-75% is rejected as heat without being turned into useful work, i.e. turning the crankshaft.[1] Approximately half of this rejected heat is carried away by the exhaust gases, and half passes through the cylinder walls or cylinder head into the engine cooling system, and is passed to the atmosphere via the cooling system radiator.[2] Some of the work generated is also lost as friction, noise, air turbulence, and work used to turn engine equipment and appliances such as water and oil pumps and the electrical generator, leaving only about 25-30% of the energy released by the fuel consumed available to move the vehicle.

@ engine efficient at burning gasoline - Bing

NOTE the 25 to 30% efficiency…

There are more detailed report saying that the reason for this inefficiency is that gas in a liquid state is injected into the engine, even as a super fine mist it is still liquid, only a small part of it vaporlizes within time to make power…(see above)

The rest is burned BUT not making any useful power, it is the waste heat that heats up the motor and is lastly burned in the Cat.


Now if you only let in the Vapor ..say only 30% and it all is burned during the power stork, and there is nothing left over what happens?

Burned is burned, same amount of oxygen, same amount of carbon, same amount of hydrogen, same engine wasting 70% of the heat energy.

Where does vaporizing the gas early help? How do you inject that? Or do we go back to carburation as a means of fuel introduction? How do you not blow yerself up?

A) By being only vapor you can burn all of it during the PS.
B) No, well not into the engine or intake, you inject it into a prechamber, and make vapor.
C) Kind of, the trick is we suck in air and add gasoline, to do this we tank a little gas and run the air though it lifting the vapor.
D) That is one of the major problems.

You come across as trying to be a learned fellow, yet, somehow basic concepts in chemistry and thermodynamics seem to be no reason in your mind to spoil a crazy idea.

I don’t think so read above…again.
