i was visiting with my dad Saturday and he and i were rummaging through piles and boxes of crapola in his shop and we came across a project the two of us were messing with back in the 70's... the main vapor chamber from a pogue vaporization carburetor. dad told me to haul it home and see if it was worth the time and effort to finish the thing... anyone here ever seen one working or know more about them? the principal is sound, heat your gasoline with exhaust heat and boost efficiency thus increasing gas mileage and dropping emissions... i dont mean to start a shitstorm, but with the price of gas, if a guy could build one, and it works without major loss of power why not? T
it's one of those things that sounds like it should work, unless you happen to know enough about automotive engineering to understand that it won't work. Fact is that almost all the fuel in any engine gets used to make power or heat. Carburetors vaporize it just fine, what doesn't get vaporized in the carb does get vaporized in the cylinder and burned. You may not believe the laws of physics and chemistry, but you can't break them.
Some famous car guy (could have been Smoky Unick but don't quote me on that & don't critique my spelling) built an intake that had the exhaust going through it & got incredible mileage. I may have more info on another computer but they are not hooked up at this time & one is not working. You can increase mileage, but you loose power. I think it works to also heat the intake air but not near as well as the entire charge. ~ Paul aka "Tha Driver" If at first you don't succeed, destroy all evidence that you tried.
I would say that if every inventor asked if something could be done then nothing would have ever been invented...just from all the guys saying it can't be done! i.e. a guy on here a couple of years ago decided to build his own intake. A whole bunch of engineer type guys (and wannabe engineers) told him his design was way off and it would never run. This guy is pretty hardheaded and says screw it I'm building it...ran great and still running. Point is...the only way to really know if it will work is to figure it out ,make it run and then tell us how it is!!
Good point, but in this case everyone in the world has been wanting to do this for a long time, many have tried and all have failed, and many scientists can explain exactly why it won't work. There are ways to get phenomenel mileage, we got about 500 on our high mileage car in college, and the folks who won the contest got over 1500. But that's a car you could not drive in the real world.
ONLY? Obviously you make more than $5,000 a year.... ~ Paul aka "Tha Driver" Experience is something you don't get until just after you need it.
So exactly what's wrong with trying to get 50 or 100 (or even a 10% increase) in a "real world" car? All of that is possible, & this country desperately needs to be less dependent on forien oil. ~ Paul aka "Tha Driver" For every action there is an equal and opposite criticism.
Jezzz ... I hope you don't consider Canada as one of the OTHER Countries! We are the SECOND LARGEST producers of petroleum products IN THE WORLD! (and BTW, we STILL pay more for a gallon of gas than you do!)
Nothing wrong with it, and we do know exactly how to do it, but you and I and most other Americans don't want to drive the little crackerbox that gets that kind of mileage. The 100 mpg carb is a fantasy scam, some con artists have made money on the concept, and conspiracy theorists love it because it makes a great urban legend. In real life, an intermediate sized car can get 20 to 30 in town driving, and 30 or so on the road on gasoline. It can get more mpg if it has hybrid help, and even more if it's a diesel. But it takes a certain amount of engergy to move that much mass on tires through the air at speed, and there is only so much energy in a gallon of gasoline, and there is only so much efficiency possible in the thermal cycle of an engine. You are welcome to pursue the 100 mpg carb, you'll be wasting your time until you finally decide that it is a pipe dream...only then will the learning be complete.
Ahh, ... finally, a "short and sweet" reason why a 100 MPG carb is a "pipe dream!" Squirrel; you must have stayed awake in "Physics 101!"
In the mid 70's Detroit came up with a high milage carb. It was called"computer controlled fuel injection" go figure..??Sparky
Interesting article.When I worked at the Mercedes-Benz dealer,one of the stories in their propaganda newsletters concerned a yearly competition held by M-B for their engineering students. The rules for car building were similar(all used a single cylinder diesel engine and a minimum and maximum speed had to be maintained)and some of the vehicles were quite wild.The engines were started and run up to maximum speed(18mph I believe),shut off and coasted back to a minimum of 3mph where they were restarted and the cycle begun again.Only a liter of fuel was allowed and the mileage results were extrapolated. The winning vehicle one year had a calculated 3,000 plus mpg! A sidebar noted that a lot of people believed at the time that streamlining wasn't a factor in cars that went so slowly but that theory was quickly disproved. They ran the car both with and without the streamlined body and the mileage figures were cut nearly in half! Sort of makes the case for having an efficient body design doesn't it?
Well...it depends on other things. If the tires are very skinny and high pressure, and the car is very light, then the rolling resistance will be so low that aerodynamics will be important at low speeds. On "normal" cars, rolling resistance is so high that aerodynamics actually are not important until you get up to 40 mph or so.
Me neither, actually. I scrape buy doing some paint/body work & selling a few parts on a couple news groups... ~ Paul aka "Tha Driver" Plan to be spontaneous - tomorrow.
