If you want higher mileage the efficiency of the internal combustion engine has to be raised. One of the advantages of an ICE is it's wider range of operating rpm compared to diesel. The disadvantage is that the efficiency is low because the burning fuel wavefront does not match the piston speed. Adding hydrogen gas or water vapor slows down the wavefront and improves efficiency. Supermileage closed circuit "cars" run on lawnmower engines have no brakes, alternator, lights, power steering, etc. and have expensive high precision very low friction wheel bearings. The engine is run only long enough to get the car up to speed and then it's cut off and the car coasts. You can't make and operate a street legal automobile in a way the will get 1000 MPG.
Cars today don't get any better mileage than 30 years ago because the EPA has watered down gasoline with alcohol to lower carbon emissions and have forced car makers to lower compression ratios to eliminate nitrous oxide emissions. Cars today last longer and don't pollute, but they cost more to operate.
A fuel vaporizer on a car is called a throttle body injector. 1980's technology.
Congrats genius you've replied to my thread that's more than Six years old.
Thermo Electric Generator (TEG) is not expensive anymore, its like 4$ for 60W module, so at around 50$ a 1KW unit can be built easily, and HHO off a 1KW would be roughly 5 Ltrs per minute, which can be very useful in boosting Mpg ;)
HHO should work fine and not come up against the laws of physics if the alternator is NOT used to power the electrolyzer. Instead, thermoelectric generators powered by the vehicle's waste heat should be used to power the electrolyzer in a standard, non-hybrid vehicle. The engine will not work any harder to power a TEG, since waste heat is a byproduct of any running internal combustion engine, so the HHO from the electrolyzer would be a source of extra fuel with no cost in performance. This would raise efficiency levels.
This could be done, it would work, miles per gallon would go up, and no one could could feasibly argue that the physics don't allow it. After all, using the engine's waste heat is using a valid source of energy that routinely goes to waste. If that energy is captured and used to generate HHO via a thermoelectric generator and an HHO electrolyzer, it should reduce the amount of gasoline consumed per mile in a gasoline vehicle.
This could be done and there are advantages beyond higher mpg, like cleaner emissions due to HHO's ability to more thoroughly combust gasoline, but I'd bet no one even bothers to try due to the upfront cost of a thermoelectric generator. Let's face it. People won't really give a crap unless there is a true energy crisis, a situation where fuel is too expensive or truly in short supply.
If HHO generation on the fly could be done, then please go and do it, but I know it can't, and I haven't even got a degree in physics, I do have common sense though and know that to split Hydrogen and Oxygen, you need twice the energy input into separating them than you would get back, it's a simple case of ever diminishing returns. It's not worked to date, and doubtful that it will ever work in the future.
You're absolutely correct, you do not have a degree in physics. We'll have to take what you "know" with a grain of salt. :)
Thank you for your comment.
