I am also still trying to

figure out how an Etec injector works. The Ficht used a metal rod

driven

by an external solenoid. What is the difference in Etec? Got a

patent

number or two?

Hi Del,

It's been a long time.

Check out Patent No.6398511 B1. It works like an audio speaker where a

pulse

of current makes the "armature" move forward, then an opposite pulse

stops

it and returns the "armature" to its home position. Unlike the FICHT
injector, it does not depend on springs to return it to start its

cycle all

over again. It still is a "linear motor" attached to a pump, but

according

to the factory folks, it is not only more precise in delivery and

supposidly

operational up to 10,000 rpm, but it can "pump" more fuel in a shorter

time

frame so higher horsepower motors are possible. That is why Yamaha has

to

use such high pressures, now up to 1000 psi, is to flow enough fuel in

the

short amount of time it has between exhaust port closing and igntion.

They

still have to start fuel injection before the exhaust is closed and

that is

why they cannot meet 2008 emission specs, but only the 2006 ones..

From what I understand, OMC was working on this years back and now
Bombardier has the resources to get it into production. It is a

Bombardier

patent and is not infringing on any Ficht family patents so they do

not have

to use the FICHT name.

I haven't gotten to see or play with one yet but reports from the

field

testers say the E-TECH idles very slow and doesn't even ripple the

water

because it is so smooth. Time will tell when the production models

roll off

the line next month. According to Bombardier, by next year's model
introduction, they will be the first company to have all their motors

meet

2008 emission limits.

I did watch a 3hp rope start E-TECH run 2 years ago. Carbureted small

hp

4-strokes can't meet the more stringent emission levels, but E-TECH

can.

Thanks for the patent pointer. The voice coil in a speaker or in a disk
drive is in a magnetic field from a perm. magnet, and is attached to the
cone or arm. I'm having trouble figuring out how the voice coil creates
the fuel pressure. Push on a rod or diaphram maybe?

I'll take a look at the patent when I am on wideband.

I mentioned at least a year ago that Ficht were mucking around with
capacitors, trying yet again to get something for nothing (NB patent
date 4 June 2002).

In short this is Ficht sans the name & if you read the patent look at
the effort they've put into making sure there's no mention of what
happens inside the "pump" part i.e. it's still the same old impact pump
with the same original defects from 98 not enough pressure, not enough
flow, not enough atomisation & still trying to meet regs with lean
mixtures, all = detonation failures in too high a percentage to be a
commercial proposition.

As I suggested when I first mentioned the capacitor thing, they are
well aware of the problem but have no solution, this is just more of the
same old OMC experimentation with consumers' money!! They've increased
the size of the electrical system so much that now they're trying to
milk as much energy out of it vs times available, as possible, trouble
is it's literally re-arranging deck chairs on the S(unken) S(hi.) Ficht.

It can't work any more than the original Ficht did & as then, the same
NG dealer lackies will deceive, spruik & BS.
