Here it is ... with doping you find the consumption of a "cool" driving but by "typing in" ... and in town ...

Have you ever "banged" in your car?

Hello,
1,5 to 2 liters / 100 more with diesel, it can be done but you have to hit hard anyway and they must not have changed their habits after installing the system.
It would be better to start from the Byr consumption with an eco-driving and bring it below 4L / 100.

Logically, the arrival of the carbon tax will surely speed things up and the other town halls will surely take this route, after all, their vehicles are our taxes.

At the beginning or I had my XM, I consumed about 8 l / 100 km on average.
Now I'm at 5.9 l / 100 km.

The difference ? Eco driving very thorough and a little mixture.

So it's not difficult to have +/- 25% consumption on the same vehicle ...

There you are right. For my part, I would tend to think that there is a "psychological" effect which encourages to consume less when one is aware ...

But whatever the case, the performance obtained is significant, especially if it is obtained:
- in the time,
- on an unassigned vehicle,
- with several conductors.

Yes, lowering consumption is not difficult but it still requires some very advanced driving efforts as you say.
But that's why I find the analyzes of consumption very subjective.

Hello

Seeking to consume less with a car and seeking to improve a water doping system is a different approach

Our test bench is the road
So you have to do it by comparison
Same speed, same route, same weather

If we do tests driving at 100kmh on the highway
compare with doping and without doping at 100kmh


If the measurements were not carried out before the installation of the system, we can refer to the manufacturer's figures,
but I proceed differently, (my figures measured before water doping was lower than those of the manufacturer)

The manufacturer gives
90kmh 8litres
120kmh 10,9 liters
City 10,4 liters
measured on several journeys at 100kmh between 8,8l to 9,5 liters

I took 9 liters for my basic calculations at 100kmh
I do a determined route I do it in the same type of highway driving 100 km / h at the cruise
without dry bubbler water, which will give my calculation basis for the other tests with water.

Now to say that the test made by a fleet of vehicles of a municipality is not valid ?? it is to look for lice, it seems to me that when it is spread over a year and many km the errors are minimized.
the km traveled and the total consumption remain comparable values ​​before assembly and after assembly, and I would be surprised that the drivers change their way of driving.

One 306 diesel = one fleet vehicle of a municipality?

Certainly, but as said lumberjack, there can be "psychological" effects that encourage you to consume less when you are aware.

There was also in France a general decrease in the consumption of cars following the radar policy on each straight line by more than 400m and increase in the price at the pump ... many people have eased their foot either for themselves or for his boss...

I have probably made a false opinion on water doping and pantone ... personally I do not believe it and I can not even try given the type of trip that I make every day .. .25 km of village crossings alternating with peri-urban roads where you drive at 70 ...

But it seems that it works ...

Yes for the radars but especially the drop in maximum speed and the increased repression.

So much so that in 2004, some clever tax specialists wanted to impose the lighting of daytime running lights on all vehicles ... as for the environment, the scrapping bonus and perhaps the carbon tax, the real reason was not the publicly declared one ... : Lol:

Yes, lowering consumption is not difficult but it still requires some very advanced driving efforts as you say.

This is not the point I want to highlight ...
What I'm saying is that on the same vehicle, depending on the use, the drivers (or the way of driving, it's the same thing) and the topography of the places, it is not surprising to find +/- 25% consumption on the balance sheet.

SO, contrary to what you say, a difference of 1 to 2 liters per 100 on the 306 D is not really surprising and it is not necessarily necessary to "hit it" ...

I put your sentence:
[...]Hello,
1,5 to 2 liters / 100 more with diesel, it can be done but you have to hit it hard anyway [...]

No, it is on the contrary very objective since these are NUMBERS, which is more if the measurements are carried out over fairly long durations and in before-after comparison.

Cdlt

Note, however, compared to my remark, that this effect will be felt all the less since there are many drivers on the same vehicle and they do not pay for their fuel ...
Finally, do all the drivers of this vehicle have "the green fiber"? I doubt...
