mechanical fuel injection again.....

[brutus t maximus]

let me start off by stateing the following.

1. i have no interest in EFI or its derivitives or retrofitting EFI to old hillborn, crower, or enderle et.al. systems.

2. i understand that the aforementioned mechanical systems are not at all street friendly, and are intended to be "race only" systems.

3. i have many years experience with direct injection, indirect inject, PT injection, bosch mechanical injection etc used on diesels. so i have the basic knowlege of how those systems work.

4. i also know how the bosch CIS systems work, although i am not leaning in that direction.

5. i want a system that is low pressure, nozzle above the throttle plates, that tailors the fuel delivery by means of 3 inputs. first is throttle position as in alpha n systems, second manifold pressure as in speed density systems and third engine rpm.

i think i have a start for a design using a 3 way differential lever to control the fuel system flow referenced by these 3 inputs.

what i am looking for is an individual or a group that works on similar ground up designs.

every site i see online wants me to go the EFI route or ridicule, which i think is bullshit to the 9th power.

anyone know of such a site that deals with something like i have described or someone that is working along these lines?


would there be any interest in a system such as i have described that worked relatively well that could be understood and tuneable by the average rodder?

or am i out on a limb by myself?

Woodward Govenor makes 3 dimensional cams for missle engines. Maybe a search will give you some more info of such a device. I've only seen one, which had a lever and shaft for rotation and a spool with pressure on one side, a spring on the other for changing the depth, and profile, on the lobe in relation to the follower. It was the central control for a mechanical fuel metering device.
I don't know if anything like that would be useful to you, but hey, it's a free idea, for what that's worth.

Have you got the catalog from Kinsler ?

We ran mechanical timed injection on a 2 liter Hart motor is Can Am back in the mid 80's.
Kinsler had reworked a metering unit we borrowed from another team after ours siezed.
Our motor always ran well,
but never ran as well as it did with the Kinsler modified metering unit. http://www.jalopyjournal.com/ubbthreads/images/graemlins/cool.gif
And the giy who owned it,wouldn't sell it when he saw how much faster our car was. http://www.jalopyjournal.com/ubbthreads/images/graemlins/mad.gif

thanks for the input guys,,, still hopin for a group or individual that is working along these lines.

oh well maybe they are hiding out

this place has some serious forums stuff on and the peopel are thinking along your way also, both sites are good to hook up with some one

the second link is for tech but reading some posts alot of people are out there loking for some thing similar to your ideas
