Looking for help building a Gas Vapor system

[teoman]

Diesels like cold dense air.

Gasoline engines have to go to lean burn which not all of them achieve too well.

Here's a link to a great conversion tool to try and get your head around British vs US volumetric measurements.

Right is it is 0.8326755 to a US Gal...

As for your other crack, explain...

A MPG is a factor of how much power an ICE makes from gasoline, and as my Ford has more power with cold air and much less with hot air, then it seems correct that I get more MPG as the only variable is the IAT as the computer maintains everything else like the A/F ratios etc.

So is the English mile the same as the US Mile??

As for heated the current intake, I see a MAJOR lost of power here in the summer even with the engine holding its running temp at 190 with 110 degree intake air.

And when it gets cold a big power boost and better MPG in the cold winter air temps.

SO in my book colder intake is better.

Rich

The English and US mile are the same.
I successfully tested my switchable cold air and thermostatic intake it worked great. The switchable intake gives improved fuel economy or full power when needed. Now all I need to do is automate it.

No.

[racprops]

Really?? Back that one up will you.

Miles Per Gallon is the measure of how far a vehicle can travel on a gallon of fuel. How much power the engine makes is not relevant as long as it can move the vehicle.

Volumetric efficiency is helped (a little) by cooler air, but that hurts FE rather than helping it, by causing the engine to use more fuel at idle.

I disagree, it takes a certain amount of HP to move the car, over coming wind, tire, internal friction ETC. to maintain a set speed.

SO IF that HP can be made with less fuel, then you get more MPG.

There are many changes that can help, higher compression ratios, and a stroker crank making more torque could make more HP/torque with less fuel. or a more powerful fuel also.

Volumetric efficiency is helped (a little) by cooler air, but that hurts FE rather than helping it, by causing the engine to use more fuel at idle.

As for idle I have two gauges that show the GPH at idle and hot or cold it uses the same .45 to .60 GPH depending on rather the A/C compressor is engaged.

AND idle has very little to do with MPG unless left idling for long times...

The car was stripped and had a two speed chain drive.

The engine was heavy wrapped to run super hot.

The carb was from a very small lawn mower, it was just big enough to bearly power the motor.

I believe the fuel was a special blend.

The only trick left out was a down hill run.

So no it is NOT relevant, as it is no way a by any stretch of a car anyone might ever drive.

By your analysis and admission, neither is the Pogue Carburetor equipped car which pretty much followed the same formula to 200 mpg. Thus I expect you will desist from bringing up that device as an "example" of high mileage possibilities, in the future.

Xist bringing up the Shell Eco Racer as a parallel to the Pogue Experiment is relevant in that they are similar exercises. Most people who use the Pogue carb as a miracle device do not look deep enough into the experiment to realize it is impossible to separate the other variables that contributed to the 200 mpg end result.

Like those long downhill stretches in Nevada? Idling at rest is always zero(0)mpg.

It falls out of the equation, so it's a factor.

I agree with you, I have not used the Poque carb as a point...I can see it could NOT produce such MPG in a real world car driven normally.

It at best could only produce a little vapor and at best given a small improvement in MPG.

There was no system to completely vaporize the fuel.
