May 25th, 2007 11:52 AM #1132Skipping a beat could be best explained by fuel injector or injction pump clogging or water in the fuel tank. My bet is the fuel injector clogging. Biodiesel burns better burning carbon residue at the tip of your injectors and has solvent properties dissolving wax buildup in your fuel lines.
Best,

nakow... may away na naman
let me butt-in to calm down our colleagues and mediate :D
on the refining of cocodiesel to get PNS or ASTM specs :
-simple and straightforward answer : yes, homebrewers can refine cocodiesel to pass the specs. Fairly simple lang yung process, hint --> try looking up the process described in the biodiesel forums and journeytoforever.org. The thing is, how to analyze if you indeed passed the specs. You'll need some chemicals/reagents, lab glasswares and some knowledge on chemical titrations. Or better yet, why not submit it to DOE for analysis. They'd gladly accept your samples.
on why cocobiodiesel is better:
coco oil has a very high amount lauric acid fraction (about 50%), this fraction is converted to sodium lauryl sulfate (SLS) by the soap and detergent makers since it is a very good detergent. This detergency property is imparted to cocobiodiesel, that is why some claim that CME has the best detergency property - it has an inherent cleaning property. CME has also been tested to have a high dissolving power- this I know for myself since we've tested it in the lab. And lastly, there are findings that in terms of pollution reduction, CME not only lowers the airborne particulates from diesel engine emissions but also lowers the NOx (nitrous oxides) levels vs. std. diesel. I've heard this claim from an American technie guy who has subjected the CME to various tests and whom I've met personally.
so there, I hope this settles some of the issues you guys raised.
disclaimer - I don't work for the big three oil companies. Pls. don't PM me on the refining technique-- do your research on the net and you'll find out how.

Nagiging more interesting na ang topic.
Na rate na ba ng API ang BTU heat content ng biodiesel compared to regular diesel?
How about the cetane number?
I hope it is favorable to our cocodiesel.

May 25th, 2007 10:56 PM #1136It was local manufacturers and the DOE (in brochures and full-page newspaper advertisements) that claimed 1% blends of CME can deliver 15-25% fuel savings. Yes, the NREL report never mentioned anything like this. It basically said, CME is like all other biodiesels, can be used as an additive or a fuel substitute with emission reducing capabilities.
Knowing that other biodiesels actually lowered fuel mileage and increased fuel cost neccesitating foreign governments to subsidize consumers, I was actually surprised to see "for myself" that minute (0.5% and 1.0%) CME blends indeed delivered better fuel mileage and fuel savings.
My test procedure has been previously in this thread and I am confident my results are accurate. I am even willing to demostrate them for verification purposes. What's in this for me?
Nothing really! I simply believe, by proving that minute blends (0.5%, 1.0% and 2.0%) of CME can deliver increased fuel mileage and savings because of its superior chemical characteristics, I can be helping our poor and floundering coconut industry.
Yes, one manufacturer recently provided funding for more tests -- but this is just a bonus with good intentions for everyone.
Wouldn't it be nice to know, for sure, as in "eating the pudding" that CME was really better than the others, that CME gives better fuel mileage and fuel savings on top of reduced emissions? Wouldn't it be nice if other countries knew about this and wanted CME for themselves too?
I started the thread entitled "What is your DIESEL fuel consumption?" Check it out as information on fuel consumption data using 1% CME is posted.

May 26th, 2007 12:29 AM #1137BTU rating ng BD: it's lower than regular diesel. Have the figure somewhere
tambak papers ko regarding this. Hanapin ko lang. Including cetane number. 52++ definitely.
dali lang gumawa ng BD to PNS standard. Di ba rsnald? hehehe. Nasa Net lahat.
rsnald: nice explanation bro.
Dami ng news ng mga joint ventures for bio fuels. Better for us! Jatophra karamihan ang feedstock, well in the long term of course, and sa Mindanao itatanim.
Keep the discussion going guys. Basta "going forward" ok yan!

May 26th, 2007 09:23 AM #1138For me, anyone can make biodiesel, just like anyone can make beer with a small brewery in their garage. But I'm not optimistic of a small brewer selling beer to the general public to rival San Miguel, am I?

pre, highest figure for cetane rating of cocodiesel that I encountered was 65 yata vs. 40 for regular diesel. Basta it's higher than that for biodiesel based on soya (U.S.) or rapeseed (Europe). Kaya nga yung mga Hapon, cocobiodiesel ang habol instead of the other biodiesels.
On the BTU rating, tama, it's lower than diesel. We've computed it based on the BTU ratings of individual carbon chain methyl esters that is present in CME. But I'm getting too technical here, anyways, CME is indeed lower in BTU but its higher oxygen content somehow results in better fuel combustion when it is mixed with diesel. Using it pure (100% BD) results in lower kilometers/liter but using it as an additive (0.5% - 1% levels), somehow, the fuel efficiency is improved.
Another good thing with CME pala is that it is inherently more stable towards oxidation, meaning, di mabilis magdegrade when exposed to oxygen, and will not produce by-products that will gum up the engine. I can explain it in technical terms but I'd rather leave it at that. Plus, CME I think will not need to be winterized, but this is not necessary for a tropical country like ours. Just another selling point for CME if it's used abroad.
As for Jathropa being a substitute for Coconut, di ko pa alam ang carbon chain distribution/characteristics ng oil na yan. ang alam ko lang na oil that could potentially match coconut oil in terms of biodiesel property is canola oil. But canola is not as abundant as coconut.
Dapat bilisan natin umaksyon sa CME. Years ago, we were the #1 coconut producing country. Ngayon yata, #3 na lang tayo behind India and Indonesia.
We should take advantage of our position before other countries get going. We're lucky in a sense that we are the first country in SEA to have passed a law mandating the use of biofuel in all vehicles. The time to act is now.
(update : I might be wrong with this statement, based on the statistics mentioned in this link below :
http://indexmundi.com/en/commodities...onut/2005.html
Philippines is still the #1 coconut oil producing country? )
The fantasy scenario for CME is this... If only coconut oil prices were low and stable, and if only our coconut industry was well established, we'd be the only country in the world whose heavy industry and whose main means of transportation would be powered by compression ignition (diesel) engines powered by CME. We'd be partially free from dependency on petroleum products. and to top it all, our pollution levels would be very low.Last edited by rsnald; May 26th, 2007 at 11:32 AM.

Thank You Rsnald for the inputs.
Mas mataas pala ang oxygen content. Very useful for any combustion engine.
How is the supply versus the demand. I know that a lot of industries depend on coconut by products for the manufacturing of their goods. Hindi ba mag aagawan sila dito at eventually tataas ang presyo making it more of a problem than a solution?
Tumutulong ba ang coconut authority ng Pilipinas sa mga coconut farmers natin?
How can an ordinary person like me help in making cocobiodiesel successful?
Aside from the Biofuels Act, what else is needed to make cocobiodiesel become a reliable export and earn our country dollars?
