Ford Trucks to Get 62 MPG?

Sepp Hasslberger: Pogue Carburetor, 'Gasoline Vapor Maker' Increase Mileage

For anyone interested in high milage fuel handling systems for gasoline engines.:thumbsup::thumbsup:

Mythbusters is a farce...........as was proven by the episode about a car behing sandwiched between two tractor-trailers, and becoming part of the tractor trailer.

The trucks were going at different speeds, hit the car(which was stationary), at different times, and different angles. Totally fraudulent detemination on their part!!!

Totally discredited themselves........with their own video..............go figure:confused2::confused2::confused2:

Don, they revisited the myth to correct the flaws you point out, and they fully admitted that their experiment had problems. They labeled the myth as "BUSTED" in both cases. They went on to ramp it up in another episode by strapping a compact car to a rocket sled in New Mexico and running it into concrete wall. No fusion as would be expected; but a thoroughly pancaked car with little left that was recognizable. I guess you didn't watch those episodes. In any case, true car fusion in "BUSTED" as one needs energies seen at the center of stars to start a fusion reaction.

dunno if anyone elso caught this Euro- pe-on :laughing::laughing::laughing::laughing:

Or Eur-o-peein.

The efficiency of the piston engine has something to do with physical dimensions too. The larger the engine the lower relative losses. Both friction and thermal losses are lower as the engine cylinder volume gets bigger.
Reason being volume increases with cube of dimension while surface increases with square of dimension. Additionally it is easier to contain the burning air/fuel mixture farther away from the cylinder wall keeping it cooler thus lowering energy dissipated into colling system.

Those engines have the lowest specific fuel consumption from all engines ever made. Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption). Fuel consumption at maximum economy is 0.260 lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion.
Typical modern tractor engine specific fuel consumption is about .430 lbs/hp/hour. That is about 26% efficiency.

There was once a time when you actually were able to purchase real gasoline...............

You still can buy isooctane - "real gasoline" but real gasoline has never been all isooctane so, you're wrong.

And that 'real gasoline' could be converted to a vapor, by use of heating coils, from your exhaust system.............thus an entirely closed system, changing the liqiud to a gas.

All gasoline can be converted to vapor, leave a pan of it outside and come back later... where did it go? It converted to vapor.

Liquid gasoline is only about 65% burned in the internal combustion engine, whereas a gas............is 98 to 99 percent burned in the same engine.

Sort of, but no one burns liquid gasoline in the engine, they vaporize it using high pressure injection against hot components in the cylinder. All modern engines sold in the US burn nearly 100% of the gasoline (and the other components of the fuel).

Same concept as propane, but done with.............."original gasoline", not the garbage marketed today which has caused a cancer increase of 75%, because of the 'carcinogens' that are added.

Uhm, no. Propane and gasoline burn almost the same, just happens propane doesn't need a fancy injection system to be well vaporized as it has a lower vapor pressure. BTW propane can be burned rich to produce lots of soot and carcinogens too. Your claim re gas engines causing cancer increases can't be substantiated. They used to pollute far more, and cause other problems when there were additives such as lead in the fuel.

And back in the early 80's.........Ford motor comany did install carbs on (some) F150 pickups that would get over 50 MPG(with a V8), but those trucks were promptly recalled and the carbs were changed.

The technology is there, but it is a conspiracy to get you to buy more oil!

I don't care if ya'all believe what I typed or not..............but I would appreciate it if ya'all did some research before you try to insult my intelligence!

You've bought into someones conspiracy theory, but they are outright lies, a 1980's pickup with a conventional V8 producing the same power as a conventional V8, driving on the same course and speed powered by gas, will not achieve 50 mpg period. It does not matter how you put it into the cylinder, the engine simply can't make power out of nothing.

Thats hp at the PTO or wheels, not at the flywheel like the numbers for the Sulzer are...
the average industrial diesel has about 35% efficiency.

I think that it is at the flywheel with all components such as standard exhaust, air filter, water pump, generator, hydraulic pump etc installed.

Here is a better estimation:

Typical fuel consumption at rated power of typical tractor engine
257 g/kW.h= 0.427 lb/hp/hour
Wartsila uses 0.260 lb/HP.hour they claim 50%+ efficiency

50%/0.427*0.260=30.44% That a better number than 26 I suppose..

Slowzuki; does the compression ratio have anything to do with efficiency?

 

[Renze]

Slowzuki; does the compression ratio have anything to do with efficiency?

Thats the main reason why Diesels are more efficient...

 

[Egon]

OK, if high compression is good one would think the gasoline from the olden days may not be as good as todays gasoline?

 

[Redneck in training]

High compression ratio is part of the higher efficiency equation. Another big part is small throttling loss in the suction tract.
