Biodiesel Rulez!!! [ARCHIVED]

[cocojam]

May nakasubok na bang mag full tank ng BD sa mga tsikoteers? Or rather the question is, may nakasubok na bang gumamit ng 100% BD? What would be the consequences of using 100% BD (aside of course the cost)? What about other BDs derived from cooking oils, are they inferior to cocodiesels?

What I know of is that before Biodiesel came out in the market sometime in 2002 (pioneered by Senbel), the coconut research group PCIERD had been running their diesel L300 van on pure biodiesel (extracted from their own reactor) for about 10 years already. The engine is still in pristine condition and contrary to previous reports that biodiesel will melt the rubber parts (ie. oilseals, fuel pump diaphragms, hoses, etc.) due to its solvency properties, it did not. Consequences, nothing really based on this experience by PCIERD but why go 100% (given the currenct cost/liter of biodiesel) when you can reap the benefits of a cleaner engine (due to BD's solvency action), cleaner emissions (due to lower distillation point = total combustion), and increased power (higher cetane than regular diesel) even at a mix of 5-10% BD.

Hope this helps....

I forgot to answer your last question regarding BD's dervied from other cooking oils. Actually BD's in the U.S. comes from soya bean oil while in Europe its mainly canola and rapeseed oil. Malaysia uses Palm Oil for their BD mainlya because Palm oil is abundant in Malaysia. Other vegetable oils (ie. corn, olive, etc.) can all be esterified to create BD. However, here is where the Philippines (and perhaps Indonesia as well) are very lucky to have abundance of coconut to produce coconut oil because coconut based BD has the highest cetane rating among all the mentioned vegetable oils. Petrol diesel has a cetane of only around 54-56 while rapeseed oil is around 56, palm at around 60 (kaya lang mabilis matulog becoz of its low pour point), etc. Guess what....coco BD has the highest cetane at over 60.

Hope this helps.

I have not, and will probably consider this idea if the price of diesel exceeds the price of biodiesel, and I get assurances from Isuzu that a 100% BD solution won't melt my fuel lines, and other rubber components of my fuel system. I understand that a higher than 50% BD mix is not recommended in the EU, for valid reasons.

Hi I am new to the forum.
I thought I might be able to offer help to those looking for biodiesel.

Been researching on Biodiesels for a 2 months now and how it affects diesel engines (positive or negative) seems like the pluses outweigh the minuses.

Based on data from different biodiesel sources, the only negative effect is on seals and that is with the use of blends above 20% provided the glycerine removal is adequate. According to the chemrez data, their Japan testing shows the superiority of their Coco biodiesel in this and other respects.

Actually, glycerine when not fully extracted from the BD during the esterification process can produce gumming in the combustion chamber in the long run.....same effect you get when you run your diesel engine with cooking oil. The seals (or whatever rubber parts you have in the engine) will not be ruined by glycerine but by methanol which is used in the reaction process to separate glycerine from the vegetable oil. Methanol is also taken out before the end-product BD is finally produced. All BD's have specific fuel standards the same way gasoline and diesel and other petro-based fuel have theirs. The Philippine (DOE) standards were based on the BD produced by Senbel if Im not mistaken. So ensure that your BD source meets the standard especially on the residual methanol content to ensure your seals dont melt.

FYI, the World Wide Fuel Charter standards for diesel allows up to a 5% mix of BD. This was approved/signed by know fuel and automotive manufacturers. Given this, usage of BD up to 5% blend will not even void your engine warranty.

anybody used it on a 4jx1 engine? as far as im concerned, mdyo sensitive ang injector ng trooper.. kya d ko p sinubukan..

I'm presently running on 2.5% BD for my 2003 Trooper; mileage has marginally improved, but noticeably with more torque. That's good enough for me.

Thanks for answering my questions. I'm trying to analyze, given the abundance of coconut oil in this country, given the high cetane rating of cocodiesel, why not encourage people to organize small scale production of cocodiesel? Hence, cost of BD will drop way below normal diesel; hence, people will use pure cocodiesel instead of mixing, (if it's proven that it's really safe) reducing dependence from normal diesel; hence, grabing the market from the big 3.

What dya think? I'm willing to invest.hehehehhe

betwen estrol and biotek, what is much better?

It really all depends on the government. If they wanted to push all out biodiesel, they could actually. But I guess they wont given the strong lobby force of the petro giants. Just imagine the lost revenues for them due to the substitution of BD. Shell actually sells blended diesel with BD in France and Brazil but why do you think small players like Seaoil and Flying V was the first to come out with BD blended diesel. At present the price per liter or kg of RBD (refined bleached deodorized coco oil) is still high thereby ending up with a BD price of at least P55/ltr kaya di economical pa. But if the govt will put up subsidies for the coco industry...definitely costs will go down.

Im only familiar with Estrol since I was involved in its development. I dont think it would be fair for me to say which is better. It really depends on their specs. As long as they meet the DOE standard for BD, it should work fine with your engine.

Welcome to the tsikot forums cocojam, and particularly, our lengthy biodiesel rulez thread. Nice to have somebody around with a wealth of experience on Estrol, and coco-biodiesel in general.
