diesel tractor: how to purify exhaust gases?




by Mio » 05/04/07, 09:54

Hello to you,

I hope I'm in the right forum if not, please excuse me.
I see that there is a lot of talk about legislation, standards, tax incentives and quite a few theories and also that there are many competent people, so I would like to submit a little practical problem to you.

I just bought a small agricultural tractor to do various work on my property, because my muscles became faulty with age.
Of course this tractor (new) has a diesel engine and the seller, kindly refilled me with "red" in other words domestic fuel.
However, although I am in the open air, the smell of fuel oil already bothers me enormously, I would even say that this smell alone prevents me from approaching the tractor, but obviously there are the gas exhaust when the engine is running! I specify that I live in the countryside far from any source of pollution.

For the smell of fuel oil when stopped, the solution seems simple to me, it is to replace the "red" with "white" but for the exhaust what to do?
To come back to the domestic fuel oil which is still cheaper, I wonder what abominable product is added to it which causes me unbearable headaches, and if its biological toxicity has been studied?

For exhaust, since it is a tractor and I can add all the accessories I need, I mean I have room to do it, couldn't we imagine a filtration of these gases? I had heard that at the bottom of coal mines, the exhaust of diesel engines went through a "water tank", which seems to me a pretty logical solution. Researches on the Net did not allow me to find information about them.

While we are at it, could we not envisage a total purification of these gases.
Now if there is a solution (water, chemicals like quicklime, activated carbon, what do I know?), How do you calculate when the substance used for purification is saturated and what to do with the waste?
Could we also consider using another type of fuel that is more easily "treatable" in terms of releases?

I thank you in advance.

Hello
Why not "pantonize" your tractor? The pantone device is one of the main subjects of Econology (see the different forums).

hi and welcome mio

: Idea: rather than thinking of purifying think of not producing pollutants

Put on a pantone and turn to PVH and all your problems will be solved.

If you need advice you will find everything you want on this site and for PVH on oliomobile (link above).

just in passing we say HVB for raw vegetable oil, not HVP for raw vegetable oil :)

Otherwise, if you want to pollute less, you can already try to put a slight percentage of rapeseed oil in your diesel.

Me, I turn 10% in a 205 TD, already we see the difference, much less smoke.

I did the test on 2 consecutive technical checks, the exhaust gas opacity test. The first with 100% diesel, gave about 1,00 to the test.
The second CT, I had put 20% of rapeseed oil in the tank the opacity test had fallen to 0.65.

With a low% of rapeseed oil in diesel 10%, 20%, 30%, you do not need to modify the engine by adding a fuel heater.

In any case, I haven't made any changes, my 205 has 390 kms.
Once hot, it is even quieter.

Nico.

hi Pastekos

We say crude vegetable oil (HVB) for "new" oil from rapeseed or other, but we say HVP PURE vegetable oil (roughly filtered stew); which for me is ecologically much more interesting because it is a recycled waste and not a culture made to the detriment of food crops : Cheesy: : Cheesy: : Cheesy:

It was not a mistake, that said it also works (a little worse) at the HVB.

Thank you,

Why not "pantonize" your tractor? The pantone device is one of the main subjects of Econology (see the different forums).


I did not quite understand what a pantone was for, but I have the impression that the principle is not unanimous. Anyway this is not what I am looking for, I am not trying to save money but to absorb all the pollutants.

rather than thinking of cleaning, think of not producing pollutants.


My tractor is already producing pollutants, what I would like to do is absorb them so that there are no more. It seems to me theoretically simpler than to change fuel which in any case will produce other pollutants different from the first, and which will have to be eliminated anyway.

The operation would consist, if it is feasible to add a "filter" at the outlet of the exhaust without modifying anything on the tractor. I am not sure what would become of the warranty (it does not have an hour of operation) if I put oil in place of the fuel oil or if I modify the fuel supply systems.

From my recollection, it would seem that it is enough to bubble the exhaust gases in a water tank to somehow wash them. This process was used at the bottom of coal mines, it must have people who know this?

Kind regards.

The aim of water doping (sending a certain quantity of water vapor into the intake, under certain conditions = device derived from pantone) is not only to consume less, but precisely to clean up the engine to the crankcase oil stays clean and so does the exhaust.
As Zac, a great specialist in this field, writes, the ideal is to run on vegetable oil + water doping.

While waiting for the answer from someone who knows this process, maybe you could try to extend the exhaust in a container of water to see what it gives?

Thank you for your response, which seems more appropriate to me than the “oiled pantone”.
That is exactly what I intended to do, but I wanted to collect a minimum of information beforehand; For example, the gases should not be prevented and the engine "explode" or have difficulties. Nor should there be a vacuum, for example when the engine is turned off or stalled, and a rise in water in the cylinders. The device now has one hour of operation.
On the other hand I confirm, the pollution by an agricultural tractor which rolls in "red" and that one is perched on it, it is unbearable!

Kind regards.

I confirm: HVB + Pantone (water doping) is the "more better" currently : Cheesy:
