Hello everyone!!
Here are the results of my humble experience in process:
The pollution control is ok
Date: 19 / 09 / 2008
320 991km
0.00% vol Co________
% Vol Co corr_____0.00
% vol Co2________14.9
% Vol O2_________0.57
ppm flight HC_______0015
Lambda__________1.026
Since I'm 322 089km
I spent wiring shielded wire, re-worked my CR and ... no noticeable change ...
Until I get a used collector with its probe.
I tested it on 200 last km, I have to refuel, and guess what: 6.12l / 100 on 280km - drop it!
The lambda sensor indicator seems to react better also ...
So the old probe seems wrong in retrospect (I would have tried with a new probe ...)
320 000 km with a lambda probe, it is far from 80km 000 recommended for replacement!
Anyway, another thing teases me: constant speed, toward 100km / h, the lambda value is greater than when I'm on the motorway or in full acceleration (mostly uphill).
Motor load seems a key factor, and therefore, the type of feed received by the probe.
Let me explain: at full load I think that the flow of exhaust gases is laminar and the probe provides a correct indication (at least close to the values I'm looking for) ...
At 100km / h, in steady speed, I suspect the flow to be swirling, and because of this, the probe only gives an approximate value of the actual mixture.
The calculator corrects too much due to this vortex flow?
(This reminds me thinking that I had done it years ago, about the fuel consumption that seemed more than respectable in 140, compared to those found at lower speeds.)
Has anyone already done the same thinking?
Because logically, the power required to maintain 140km / h is greater than that required to 100km / h.
Similarly, the drag increases well with the square of the speed (if I remember correctly)? So, differences in consumption should be obvious ...
Or, the collector is designed for optimum performance at full load, which coupled with the reactor, gives such good results when the motor is loaded ...
I'll see if I can improve that!
Other gadget: a rectangular signal generator (base NE 555 - be indulgent, I'm just starting out in electronics

) Adjustable in amplitude and frequency, always with a lambda value indicator.
This will allow me to clear the probes (compare their values) and my previous installation ...
I'll perhaps see a little clearer

!!
As for my good old Vectra, this week, I change his gasket (since the time I had to do it!).
Soon 7000 km Gillier with Pantone-assembly, it will allow me to visually check (ah Saint Thomas!) The benefits of the system on engine cleanliness - the camera is ready!
Soon for new
Econologiquement your,
