fuel vapour injection system
 

Hello everybody

I found some very interesting patents: https://www.google.com/advanced_patent_search?hl=en

my goal is to build an easy to produce vapour system to install it on a gasoline/ diesel engine.

Patent: US4458654 A

you like to discuss it?

looking forward for some interesting thoughts

You first.

With your first post started in the UC, I have to assume you know vaporizing fuel before injection does not significantly change the thermal efficiency of the engine or the combustion efficiency of the fuel.

Given that, are you looking for further refutation of this idea?

Hi UFO

thanks very much for thoughts, I don't want to refute that at all.

I have already an HHO dry cell system installed. I am just about to change the PWM and EFIE controller. With the new PWM/EFIE I should get better fuel economy results.

With the old system, fuel economy about 3 %.
with the new system, I am sure to get more.

But with a HHO system the fuel economy is limited, that's why I want to try to vaporise the fuel first.

Hi wickydude
thanks for that link.

I called this guy (463 mpg) even up for some ideas/ plans, unfortunately I didn't get any useful infos from him.
But he did something outstanding.

I wish I could build a system like half the economy from him.

You didn't get any useful info because it's a scam. Doesn't work. Better find something else to fill your time. Thought you'd get that from the linked thread.
Unsubscribing...

Can you explain how you expect to get increased fuel efficiency by vaporizing your fuel if you understand it does not change thermal or combustion efficiency?

I think when you can inject vapour only into your burning chamber, it would give me better fuel economy.
A lot of unburnt fuel goes out the catalytic exhaust.

In patents by manufacturers which sited that patent, they seemed to focus on cold starts, but not continuously trying to vaporize fuel. Which lead to me finding so information on Delphi heated injectors, focused on improving cold starts when using ethanol. The injectors were heated for 4seconds before cranking, and then left on for 86seconds

In Figure 15 we can see that although focus was not fuel consumption improvements, the total obtained reduction was 0.4% during FTP75 emissions cycle. When heating was activated the burned fuel decreased from 43g to 36g and fuel at exhaust (unburned) decreased from 7g to 2g. http://delphi.com/docs/default-sourc...f.pdf?sfvrsn=0

Woohoo 0.4%! Take that unicorn corral!
