The Toyota Prius already does this. I recall reading on I think edmunds.com about how someone thought that there was something wrong with his car because he would hear it making a noise after he turned it off, which turned out to be the coolant being moved into a special container that would keep it warm for at least a few days.
why don't they use preheaters in gas engines?

I don't know what my fuel temps were. I just made a simple homemade device. ran the gas hose to a long aluminum tube attached to the radiator hose. In summer it made my engine ping. I am not sure It got heated up very warm in the winter though, because there should be some mpg improvement in very cold weather if the fuel is warmed.
I wonder why it pinged?
Thanks for the feedback.

because gas is sprayed with a fine mist into the intake on a gas engine it will immediately become the same temp as the ambient temp in the intake runner, no matter what temp it is in the fuel system. then the gas/air mix sits in the cyl during the compression cycle further giving it time to heat up. whatever preheating you do will be undone or overdone during that time.
diesels are injected directly into the cyl and the fuel is immediately burned. it doesn't sit in hot areas first getting warmed up before it is burned. that may be why it makes a difference to have the diesel fuel preheated.

Great info. Thanks
I see your point. If I had a cold air intake, it basically would just cool the fuel and visa versa.
I have to see if I can find some literature on the concept.

Maybe I can use Peltiers to bring the gas beyond coolant temp.
They worked great in my over clocking days. I will just use it in reverse.

You should look into Hose in Hose(HIH), or hose on hose(HOH). Most SVO users are using or making it. You run your fuel line through another hose that has coolant flowing through it. You can also look into heated fuel filters, or even injector line heaters. SVO users use it to lower viscosity of the VO so it more closely resembles diesel.
Awesome thanks. I will look into it.

OK!
Do you have any information on fuel heating, besides your opinion on it? I don't want to discuss payback to customer or company.
I am just looking into anyone who may have tried fuel heating on gasoline vehicle.
Nope I don't have any info on it.
But I gotta ask, if you didn't want to talk about those things then
a: why did you reply to my comment?
and
b:why did you bring up electic fans?
As far as the concept of payback goes in the context of how I am using it in the business sense, you are still missing the point. But, I digress....
I can reply to whatever I want, I started the thread...lol
take it easy and stay on topic like the rest of the repliers.
Diesel fuel is heated because when at around freezing temps the wax in the diesel starts to gel . In over the road trucks I have noticed that after a long run the fuel tank with the fuel return line gets quite warm as compared with the other tank. Also gas engine fuel injecters run excess fuel back to the tank to cool the fuel system .
