fuel injection and other stuff

[glennyrosa]

Geez, this fuel injection does sound sweet. I'd love to dig a deep
hole and send my carb to Solex hell. One thing I do not understand is
the fuel pump in the tank. Why does the fuel pump have to be in the
tank? All these new cars have the damn pump in the tank. Won't an
inline electric pump work? Or is there not enough pressure?

On another subject:

From even before I put my rig in the water I knew that I'd be crabbing
the wheels to go straight. There seems to be a lot of engineering
types in this group. One would think that there would be a
commercially available 1:1 reversing gear box of the proper size that
could be spliced into one of the propeller drive shafts. And someone
is making new props. How difficult would it be to make an opposite
screw?

Seems to me that counter rotating screws would yield an extra knot and
make the turning radius equal both directions.
Probably cost more than it's worth.

I'm just trying to figure out how to make this car a little faster in
water. I understand that you can only push a turd so fast. I'm
certain that someone has gone boating without a front bumper before.
I'd like to try it to see what happens. If it works I may try to
figure a way to attach the bumper with pip pins for easy removal.
Again, any speed gain would probably be minimal to the point of
ignoring it.

<font face="Arial" size="2">There is a method I'm working on (but have been for 10 years !) to control props individually. Basically involves splitting the selector fork in half, having two rods going forward and two levers for control. Then means props can be selected forward or reverse individually. It is all mechanical and changes can be reversed. I'm sure it will work well. The clutch idea on the shaft has been looked at but it isn't really possible. </font>

<font face="Arial" size="2">Amphi won't really go faster in water - it's a law of physics - even with a big 1500 it makes very little difference. Front bumper isn't issue,you need weight distribution such the water level is below it. Remove as much weight from trunk as possible, also if you sit in the back and steer with your feet Amphi goes faster. A GPS gives you accurate results of speed. </font>

I think generally the pumps are mounted in tank to make the plumbing a
little easier. In addition, the tank serves to muffle some of the
noise from the pump. Otherwise you have to mount the pump on rubber
bussings to keep from hearing it.

Does anyone have good pictures of the EFI setup? I'm curious about the
manifold for the direct injection setup, as well as how you would
overcome the intake charge scavenging from the siamesed intake on the
Triumph motor...

That fuel injected Amphi drove really well. The engine was incredibly
smooth running with no lags, sags of misses. It starts like a modern
car, with no choke, no pressing the gas pedal and system gives the
engine a very flat power curve.

The car you saw used the original manifold with a throttle body
adapted to it though Sam Ferge is having a port injected version done
for a 1500 engine. This will need a custom manifold.

The fuel pump in the tank is a problem they are going to work on.
It's too expensive and complicted for the average Amphicar and I heard
the coast guard wouldn't approve those long high pressure lines. I
suggested a modification that would allow the original tank to be used
and also make the system cheaper as well as appease the coast guard.
We'll see what revisions those clever guys from Delphi come up with.


Had a great time at Celina. Unfortunatley, I was having such a good
time that I never got around to taking many pictures.

Re: Re: fuel injection and other stuff

I cut and paste the info about fuel injecting to a friend who specializes in British motors. I cut and pasted his reply which sorta answered my question. Why couldn't one just remove a fuel injection system from a late British car? Wait! Maybe I just answered my own question. Because it's Lucas?

Glenn (who wanted to take his car swimming yesterday for the second time and is battling a new, never been a problem before, problem with vapor lock)

Anyway, here's his comment:

The article on the complex and time-consuming adaption of computer control and
throttle-body FI to the Triumph engine was interesting but amazing he got it all
working (parts from everywhere)! All that has been standard in cars since '85
or so, would have been MUCH easier to simply lift it all from any British car of
that period (or later). The factory Metro turbo engine I'm restoring (basic
A-series like Mini Cooper has) has such a setup available, in fact I'm looking
for the computer, sensors and wire harnesses (a trip to England! maybe this
Fall). Article's mention of the increased HP, smoothness, broader torque range,
easier starting, etc. is all true, reasons all of it was done (in addition of
course to the added service revenue that would now flow into dealerships &
manufacturers!!).
