Biodiesel Rulez!!! [ARCHIVED]

[biogas.works]

Yo! Is it ok also if I will use it with old model L300? kailangan ba na ipalinis yung fuel line/tank? Paano ba ang tamang ratio kung gagamitin mo yung biodiesel?

We have been using BioDiesel on old Isuzu (non-turbo) engines older than your vehicle and they have been running much better.

No need to clean the fuel line/fuel tank. If ever dirt will be dislodged it will be trapped/collected in your fuel filter. Using 1% (or 0.5%), a very low concentration, will take some time to clog the fuel filter. I have been running it for about a year and I have had no problems.

The instructions for using BioDiesel are printed on the bottle. You can read them before you buy. I suggest you use 1% (500 mL BD mixed with 50L diesel) the first time and then try 0.5% (500 mL mixed with 100L diesel or 100mL mixed with 20L diesel, etc.).

NOTE: Mas matipid yung 0.5%. Observe your fuel mileage and make a note of it. After running 2,000+ km, switch to 1%. Observe and compare mileage, you will notice pareho lang ang consumption o baka mas malaki pa ang tipid sa 0.5%.

Mukhang naka-research ka na ng husto sa CME ah. Ano comparative stats mo ng before/after? Do you know if using CME might invalidate your warranty?

Many carmakers (particularly CAMPI) opposed the BioFuels Act because CME has not been tested comprehensively. BioEthanol for Gasoline has been used for 25+ years in the US, Canada, Europe, etc. It is a well-known fuel enhancer that is sold by all major oil companies. In the Phils, Shell sold E10 (10%) before the Act was approved and altho the Act only mandates E5 (5%).

By comparison, BioDiesels are new and very different from each other (Soya, Rapeseed, Canola, Palm Oil, etc.) The countries who can afford extensive testing like the US & Canada, naturally, only test their products (i.e: Soya & Canola.) On the internet, the US NREL only performed Emission Tests on CME. No fuel savings tests. Besides, BioDiesels like Soya BD are known to increase fuel usage instead of giving fuel savings.

CME is a very good product as it delivers fuel savings at 0.5% on top of reducing emissions but the blend cannot be lowered because production capacity is pegged to 1% usage. As we will save anyway, nobody cares if our savings is poor (or could be higher!) The lower blend will cause unsellable excess capacity that will be difficult to sell.

My tests produce 10-15% fuel savings with 1% CME. Comparatively, 0.5% CME gives more fuel savings of 15-20%. I have been testing since July 2006 using a simulated dyno to produce scientific and statistically accurate data. No local test has this level of accuracy.

Unfortunately, no one is performing tests on 0.5%. In a few weeks, the BioFuels Act will be fully implemented. Whether we like it or not, only 1% CME diesel will be sold in ALL gasoline stations. You may never know if 0.5% is better if you did not perform any tests and we will be stuck with 1% or higher blends because that is more profitable to manufacturers. Better we lose than they earn less, yehey!

NOTE: Using 0.5% is cheaper! To test 0.5% CME use 1% for the first 500 km before using 0.5%. Measure & keep track of fuel mileage. Compare and ENJOY the savings!

Biodiesel: the pros and cons
By Jim Kerr

Yumm. It was close to suppertime and the smell of french fries was in the air. But where was that smell coming from? There was no restaurant to be found - the city bus idling on the corner was the only thing around. Then I saw the decals: "Fuelled with Biodiesel". I was smelling the exhaust from the bus.


Biodiesel is a renewable fuel derived from vegetable oils, animal fat and cooking oils. Some think that these products are simply mixed with diesel to produce the fuel, but try to operate unrefined fats and oils in your diesel engine and you will soon be needing rebuilt fuel injectors and possibly an injection pump. Instead, the oils and fat are made into methyl or ethyl esters.

Soybean oil is the most common source of methyl ester in the United States, while Europe and Canada are more commonly using Canola to produce biodiesel. In a process called transesterification, the various oils (triglycerides) are converted into methyl esters through a chemical reaction with methanol in the presence of a catalyst, such as sodium or potassium hydroxide. Water, glycerols, the methanol and other trace produces are then removed from the biodiesel before it becomes a quality fuel. Sounds complicated. Making quality biodiesel isn't something that can easily be done at home!

Why go to all the trouble of using biodiesel? The answer seems obvious - it is a renewable resource and will reduce our dependency on fossil fuels, but that may be only part of the advantage. Using biodiesel does mean we use less regular diesel, but the percentages of biodiesel used are relatively small. For example, most diesel vehicle manufacturers recommend only 5% biodiesel (B5) mixed with 95% regular diesel. In colder climates the percentage may be even less.

After initial testing over the past couple years, the City of Saskatoon transit system will start using 1% biodiesel in all their city buses. They will also operate some on B5 biodiesel to test the suitability of this fuel during cold weather. While a large fleet would have a significant reduction in the amount of regular diesel they use, economical driving techniques can easily save this much fuel and more. Driver training and monitoring would have a dramatic reduction on fuel usage.

One of the big advantages to using biodiesel shows up in the engine. Analysis done on the Saskatoon city buses showed that the improved lubrication qualities of the biodiesel may increase some major engine parts longevity by as much as 100 percent. That may not be as important for passenger car drivers, where engine durability is already matching the durability of the rest of the vehicle, but commercial vehicles may be used for decades and travel millions of kilometres. Increased longevity reduces maintenance costs.

Biodiesel is also good for reducing emissions. The fuel contains less than 15 parts per million sulphur, which enables it to meet the 2007 diesel fuel regulations. Hydrocarbon and carbon monoxide tailpipe emissions are also reduced slightly at B5 levels and more at higher mixtures.

There are some disadvantages to using biodiesel. First, biodiesel has slightly less energy that regular diesel, so if we were to use a large percentage of biodiesel in a vehicle, the engine would either have less power or use more fuel to deliver equal power. Fortunately, at low percentages such as B5, the difference in energy compared to diesel without biodiesel added is very small.

Biodiesel also oxidizes faster due to its chemical makeup. Long term storage of the fuel is more difficult so additives must be mixed with the fuel to improve storage capability.

The biggest disadvantage of biodiesel is that pure biodiesel begins to freeze or solidify at temperatures above 0 degrees C. B5 diesel is commonly used in Europe and the use of tank heaters and fuel line heaters has enabled the use of biodiesel in even the colder climates. Using biodiesel during a cold Canadian winter could be a problem in older diesel vehicles not equipped with fuel heaters, although blending the fuel with different grades of regular diesel will help prevent it from freezing.

The increased use of biodiesel is a benefit to the agricultural community, creating a demand for oil seed crops such as Canola. We probably will not see more than a B20 mixture of biodiesel used in our climate, and most blends will likely be B5 or less. Even so, biodiesel has many advantages, both economically and environmentally, to make it one of the fuels of the future.

The article above is OLD. On May 2006, Saskatoon announced after "Higher Precision" evaluations that they will use 2% Canola BD instead of 5% because they found lower blends were better (i.e: Better fuel savings & lubricity. Emissions increased slightly but were still much lower than pure diesel.)

Most biodiesels like Canola BD, Soya BD, etc. have slightly less energy as mentioned above so they require more diesel. The Philippine BioDiesel known as Coconut Methyl Ester (CME) appears to be the only biodiesel capable of giving low emissions and increased fuel mileage even when used at very low percentages.

The BioFuels Act mandates 1% CME (whether we like it or not) but my own tests using a simulated chassis dyno show that 0.5% CME gives the same or better performance than 1% CME. I have reported these findings to concerned authorities but understandably no one is interested in knowing, testing or lowering the blend from 1% to 0.5% -- because that means less profits.

In fact, the BioFuels Act stipulates increasing the blend from 1% to 2% within 2 years -- even though there are no published scientific tests (done in the Philippines or elsewhere in the world) that 1% or 2% CME will deliver fuel savings benefits claimed on a long-term basis. (Section 11b even prohibits the use of lower blends.)

I envy the government of Canada (through the Western Economic Diversification Canada) and the Saskatchewan Canola Development Commission for performing and publishing a very detailed and comprehensive report. And, for choosing a lower blend because studies showed that was better.

In the Philippines, the welfare of manufacturers who will derive more profits are more important than giving motorists WORLDWIDE better savings from 0.5% CME -- an excellent BioDiesel -- probably the BEST in the world.

Please ascertain my findings. You have nothing to lose. Trying 0.5% is safer compared to using 1% CME when it will be the only diesel available under the BioFuels Act.

You only need to spend about 150 pesos (for 2 bottles of 500mL of CME) to perform the test. Add 1% CME at the beginning (or with your 1st 50 liters of diesel.) Switch to 0.5% CME afterwards and determine fuel mileage. Remember, do not follow bottle instructions, at this point, as they are for 1% CME. Keep the data and compare it when only 1% CME diesel can be purchased.

If your fuel mileage with 1% CME is the same or lower than 0.5% CME, its obvious your are using more CME than you should and are simply wasting an excellent fuel. SAYANG!

My tests produce 10-15% fuel savings with 1% CME. Comparatively, 0.5% CME gives more fuel savings of 15-20%. I have been testing since July 2006 using a simulated dyno to produce scientific and statistically accurate data. No local test has this level of accuracy. [/COLOR]

IMO.

The 5% difference between 10-15% & 15-20% savings using a 1% & 0.5% blend respectively is a bit of a stretch already in real world conditions.

People "waste" more fuel by idling their vehicles needlessly, driving recklessly, not maintaining their engines properly, etc.

If the motorist wants to really save on fuel it is really up to him/herself really.

I have to agree with you on this. As very few motorists tried using CME before the BioFuels Act was approved last month (even though CME was available for for at least 2 years before that), we deserve to use "more than" necessary because that is what we were told.

Now I can see why some companies love selling, trying & dumping their products here in the Philippines.

I am preparing a short thesis for my masters and making bd out of waste oil is my thesis statement. Nakakatuwa lang na since 1991 meron na palang test vehicle ang PCA (PhilCoconut Authority) using 100%CME. More than 50K km na na-log using Isuzu C240 engine. Of course way back 1984 nagkaroon na ng attempt to use coco oil as alternative fuel but the tests did not give encouraging results. Post ko yung mga data and of course naka footnote yung mga sources. hehe

Actually, way back in the 1970's the gov't of Mr Marcos recommended the use of CNO (coconut oil) as a diesel substitute. The PCA has 2 vehicles running on refined & filtered CNO up to today. Despite scientific data that say CNO contains impurities like glycerine than can clog injectors, the 2 vehicles of the PCA are still running.

Re mazdamazda's comment that:
"The 5% difference between 10-15% & 15-20% savings using a 1% & 0.5% blend respectively is a bit of a stretch already in real world conditions."

Please don't forget:

• 100 million liters/yr of CME that local manufacturers can produce can only be mixed with 10 billion liters at 1% while the same amount at 0.5% can be mixed with 20 billion liters worldwide.

• Even if emission is slightly higher for 0.5%, the emission for 2 vehicles using the same fuel will be ultimately lower.

• The 5% difference in fuel savings (assuming 1% CME can produce 10-15% savings although that has not been proven by anyone on a LONG-TERM basis) is equivalent to additional fuel savings of approximately 1 billion liters/yr of diesel. At $0.60/L of diesel, this additional savings is worth $600 million/yr in worldwide fuel savings.

• In the Philippines, where 7 billion liters/yr of diesel is used, we stand to save 350 million liters/yr of diesel or about $210 million/yr.

No wonder, Chemrez is rushing to build a larger plant and PNOC, Shell, SeaOil, etc. are scrambling to put up CME plants. At 1% this venture is VERY PROFITABLE for them!

The average motorist will save money but not as much as it should be. (Please check my math & let me know if I mis-calculated.)
