BioDiesel pix

Guys,
here's the url of my biodiesel pix used on my 2002 Mitsu. Adventure.

di pala sya ganon kalinis........

Doc D,
What property of biodiesel would actually remove the smoke- is it the higher cetane rating or sulfur content? Heard that most local diesel fuels just meet the 45 cetane minimum.

[Djerms]

Naku, yan din po ang sinabi sa akin ng dad ko. Baka daw makasama ang biodiesel in the long run. As chemical engineer he knows daw. Kaya ako, stop muna...

[Olive Drab]

sinasabi ko na nga ba eh..

[mdpo]

Naku... after how many kms yan? Mukhang matapang ata sobra ang senbel ah.. kasi pati yung filter niyari...

[HBOY]

change your filters and monitor it regularly.. kung kakastart nyo pa lang magbiodiesel... definitely.. all the gunk that was in your tank caused by the regular diesels will be flushed out in time.. and the most that will be hit will be your filters.

IMO... biodiesels are not bad.... initial reaction lang siguro ng tao.. kasi nga lumalabas lahat ng gunk....

Doc D, mukhang masyadong matapang ang B20 blend (or b10 ba ginawa mo). pero in fairness to biodiesel in general, sana you compared a fuel filter where you used diesel only. unless of course alam mo na itsura ng filter na diesel lang ginamit mo.
As for the residues, can't tell if they came from the biodiesel or from your fuel tank or fuel lines, or even from the diesel fuel that you regularly load. The least I can say is, at least your filter did its job of retaining those residues. To give you an idea of how potentially dirty our diesel fuel is, nung nasa CDO ako, biglang pumalya yung minamaheno kong utility vehicle (it had an isuzu engine), I immediately checked the fuel filter. nung kinalas namin, ang daming dumi, muddy and watery, halos puno na yung filter nun.
anyways, to play it safe, use up to 5% max lang. start w/ 2% (B2 blend, 1% is useless), then ramp up to 5%. Kung may mga luma kang gaskets, never go more than 5%.
First time use mo ba to pre? in any case, i'll also check my fuel filter. i went up to B10 or B20 din kasi e. pero so far, no engine problems naman. kaya naman siguro sunugin ng diesel engine yun.

to my fellow Diesel users, don't be alarmed, for now, just follow the recommended dosages, and you'll be on the safe side.

Ano nga ba ang hitsura ng fuel filter na diesel lang ang ginamit? Baka naman ganyan din.

The problem with the experiement is wala siyang "control" to comare against.

And it needs more time and more kms. para maging conclusive ang findings.

[RCM]

rsnald is right! A blend of 5% is enough to achieve 50% smoke reduction also an economical figure. You can't conclude if those residues were from the Biodiesel, I can only assure you that CME (Coco Methyl Esters), the base of Estrol Biodiesel has a high solvency factor. It literally cleans the engine by softening the carbon deposits (unburned fuel).

CME's has 65-72 Cetane rating/number and 0.03% Sulfur by weight. One thing that most of us don't consider is the presence of Oxygen, a factor we consider for good combustion. Mineral diesel does not have the presence of oxygen, while Estrol Biodiesel is 11% oxygen by weight.

[Doc Diesel]

jackaroo,
the higher the cetane rating the better. sulfur content is just second.

mdpo,
after 333kms. po yan.

rsnald et al;
I was able to see my filter before I loaded the biodiesel but couldn't take pictures of it since it was already soaked with diesel and we [my techs.] saw that it was a bit deteriorated but not like rotten.

I did not say that the residue came from the biodiesel. All I said was we saw residues after the biodiesel usage. Finding where it came is still in the process for us. It could be true that the "gunk" could have come from the dirt accumulated by my usage of regular diesel.

Pls. people don't quote me on these things. I am just merely showing you my litle experiment.

Basta the significant surprises we saw were:
1. Improved acceleration.
2. Better mileage [my 60L usually lasts a week, with this my tank lasted for 4 days more].
3. No visible smoke even at 4.5k rpm.

Doc D: Thanks for sharing results ng experiment mo. Pls take note peeps, walang conclusion na ginawa but merely observations. Try ko na biodiesel before the weekend.

[cj]

tsikot's resident chemist, rsnald has spoken!

doc! thanks for sharing the results of your experiment. please keep us posted dun sa 2nd full tank mo kung ganun pa din kadami ang residue. thanks

[Doc Diesel]

I just consumed my 2nd tank today. I'll be filling up again with the same concoction of B10 blend [got 2 carboys kasi, he he] to experiment with.

Like my first tank, I'll be slicing up my filter again to see what happens. Stay tuned..

Doc Diesel

[Bubbles]

doc, sabi sa biodiesel, initial tanks daw, check ang fuel lines and filters maybe yun nga yun. cge pls inform us madlang people

[Bubbles]

Doc, I used biodiesel for about a month. 50% blend. I replaced my filter as suggested by senbel but didn't really check for deposits. Anyway, napansin ko ang increase in engine temp. Grabe increase in power at this blend. umaabot na ako ng 110kph from a max of 90 before. pero yun nga, mainit ang temperature. on the last tank na may biodiesel ako I think nagblend ako ng up to 80 percent. mauubusan ako ng fuel so dinagdag ko nalang yung estrol. engine wasn't any hotter than the 50%. pero when I went back to regular diesel, drop to normal temp ko. do you notice the same results.

BTW, love the smell. lalo na in enclosed spaces like basement parking areas. hehe. kaya lang malakas dumikit sa clothing yung amoy.

[Doc Diesel]

Bubbles,
I did not have any experience with increased temp.'s, normal lang yung sa akin like with ordinary diesel. from my 100kph, I can now run up to 120 to 130kph without any hesitation.

last sunday, a pajero was running alongside me in an 80km route. we ran together at speeds of 120kph [more or less 3.5 to 4k rpm on the tach]. it turned out we went to the same place, when we got there, he got down, asked me, pre bakit walang usok yung sa iyo? he he

I just changed fuel filter last night. di ko pa nabubuksan yung filter para ma-check kung meron din deposits. Pero from initial observations, mukhang malinis naman yung filter. Yung nga lang, on-and-off ang gamit ko ng biodiesel. saka hanggang B3 blend lang ako. highest blend ko na yata is B20? about 2 liters in 10 liters of diesel... almost empty na tangke ko non e. It was a short test lang. Tiningnan ko lang effect sa acceleration.

as for the experience of mr. bubbles, (naalala ko tuloy yung Lilo and Stitch :D ) since B50 ang gamit mo, palagay ko mas hotter burning ang fuel blend mo kaya mas tumaas engine/oil temp. Siguro mas mataas ang combustion temperature ng fuel blend pag mas marami ang nilagay na biodiesel. Yun lang ang naiisip kong possible explanation. If I were you, I'd check all rubber hoses, gaskets, etc. where your fuel passes through. medyo matapang na solvent ang cocodiesel vs. ordinary diesel.

Pero all in all, I think we've all proven the advantages of biodiesel.

[cj]

rsnald,

pre, pag nabuksan mo yung fuel filter mo let us know your findings also. thanks!

[Bubbles]

rsnald,
everythings fine. hoses ko walang problema kasi industrial chemical hoses gamit ko.
kaya lang nagbabawas radiator ko. di kaya pumutok head gasket ko dahil sa temp. hehe. lapit na ako sa boiling point. or cud be the cheapo radiator cap.
