Has anyone monitored the difference in exhaust smoke before and after changing to an alternative fuel?

Thanks,

Don

diesel don,

Although I am not yet running either SVO or Bio, I have been doing alot of reading. It seems that smoke decreases when using bio, but so does MPG by 1 or 2. I will get back on later and post a bunch of links that are currently discussing this on the boards.

I appreciate the update as I'm trying to avoid an IP issue. '80 runs great but smokes like.....

I'm hoping that SVO does the trick.

Well, there ae two links, but I don't know if its quite what your looking for. Yoiu might just want to browse this site and do a couple searches on your own. http://biodiesel.infopop.net/2/OpenTopic?a=cfrm&s=465094322&f=066094322

There are a number of scientific journal studies that indicate that the smoke goes down, goes up, or remains unchanged depending on a lot of variables. (Type of oil, engine condition, load factors, injector condition, etc.) This topic is still in the early stages of research, with funding just now becoming available in meaningful amounts.

Of concern is that many of the studies, including the ones that say there is less total smoke, indicate an increase in the percentage of the ultrafine partcles, regarded as the most dangerous component of the smoke to the environment and to health effects. Besides the obvious pulmonary issues, the ultrafines have been solidly linked to heart problems, and probably to lymphatic cancers. More research is going on at many Universities at this time.

My 3 Benz Diesels have slightly different smoking habits.
The 1976 300D 115/114 starts much better on B-100 than pump Diesel. Of the three cars, it has always tended to smoke more than the newer 123 models. However, with B-100, it smokes less, and the exhaust is lighter in color and does not smell like a school bus. Smoking the most at cold idle, but much less after driving a few miles. This car requires "idle up" setting on idle adjuster knob or it will not start.
I also upgraded to Duratherm pencil glow plugs in parallel. Much much improved starting. This is the best thing you can do for one of these older "series glow plug" engines in my opinion.

The more modern 1981 240 D hardly smokes at all...and definitely much less on B100 . THis car really did not have a lot of smoke even when on pump diesel. On a cold morning you really can not see any exhaust condensation. Much Much less than a gasoline "vapor trail". THis car starts without any attention to the idle knob. I just leave it on low setting.
It starts and runs better on B100 than pump Diesel.

The 1984 300Diesel Turbo sedan was always a great starter. It has no idle knob for some reason and starts and runs great on B-100, again much less smoke.

Note: all of these cars have been running on 100% Biodiesel for 3 years.
No soot, no rancid Diesel smell, no french fry or fish smell,,,,just a fresh smell of "0 Carbon footprint " cooking smell. Very very rewarding.

I highly advise against any use of straight WVO in these fine cars. What a waste to ruin such a carefully built precision machine by running crap through it. Coke up injectors, rings, etc. Read Biodiesel Basics and Beyond.
They state that test show that the use of WVO will always result in the catastrophic failure of the engine. What a waste...just to save a few bucks.
I hope this information and advice is useful to you.

Prove up your dire warnings concerning the use of properly filtered and waterless WVO. There are many of us here that have seen these WVO cars run for many hundreds of thousands of miles with:
no coked injectors
no ring damage
no MFI pump damage.

If, as you claim, these engines will ALWAYS suffer catastrophic damage....
it should be easy for you to find proof and show us.

Your information and advice would be more helpful if it were actually true.

Yes it will smoke,however to control I use 1 quart turpintine to 40 gals fuel.

95 with poor cyl sealing, less smoke with bio. 97 with excellent sealing, no difference with bio.

We have emissions testing for Opacity here in the Vancouver area. I find that the readings for my vehicles on homemade B100 are less than they were on dino. This is pretty consistent over the years. I have had times where they have had to redo the test because the emissions meter indicated that the probe, wasn't inserted which it actually was. The result .1 % opacity. I also find that I can turn up the "Smoke screw" somewhat on my vehicles without producing an objectionable level of smoke. If anyone else has any objective evidence pro or con perhaps they would share. Cheers Dan

I have not seen any smoking difference in my four diesels (four including the tractor) on anything from 100% commercial biodiesel through the blends and down to 100% D2. My '87 smokes occasionally but that is a #2 cylinder problem and has nothing to do with fuel. The only time the '96 smokes is when it has a bad glow plug. The '85 has never smoked. The tractor always smokes (no ALDA!).

Whew... Another oldie! A thread from 2002.

A little smoke with #2. A little less smoke with B20 and no noticeable smoke with B99 over here. No noticeable drop in MPG or power with the bio in the one I have. Never used WVO and never plan too.

Tirebiter: I am not making that claim. Others are. The book, and see quote below. You may very well have found a way to use it that is not harmful to the system. Hopefully others can learn from your experience.

I'll have to take the book out from the library to find the references on failures. "Biodiesel Basics and Beyond" . Notice I did not add' "So it must be true". You are more dilligent than the folks I know who just either A add it to their regular fuel after filtering , and B filter it and use a two tank system.
I believe the book covers WVO as well. Always learning. Is the acidity of the wvo a concern, and if so, how do you deal with it? Good luck with your process.
