WHAT IS THE BIODIESEL DERIVED FORM COCONUT OIL?
It is called Coconut Methy Ester (CME) which has a
carbon chain of C8 to C18 similar to the carbon chain
of petroleum kerosene and diesel. CME has, in addition
to the various general advantages of biodiesel, the
unique characteristic of high lubricity and solvency
(self-cleaning property). It makes the diesel engine
more efficient. The tiny fuel pump, the fuel line, and
the fuel injector get lubricated by the fuel itself and
all dirt, grime, gum and carbon deposits in the fuel
system are dissolved.
IS THERE A RISK OF ENGINE DAMAGE WHEN USING BIODIESEL?
In the U.S., biodiesel is used in blends of 5% to 20%.
In France, diesel fuel must contain 5% biodiesel by law.
In fact, the Worldwide Fuel Charter issued by all engine
manufacturers in the U.S., Europe, and Japan allows the
use of 5% blend of biodiesel in petroleum diesel without
voiding the engine warranty. Local laboratory tests by
the Department of Energy showed that at 1%, 2%, and 5%
blend of CME in petroleum diesel the resulting blends
are still in conformity with the Philippine National
Standards for diesel fuel. Therefore, there is really
no risk of engine damage in using biodiesel or biodiesel
ARE THERE ALREADY QUALITY STANDARDS FOR BIODIESEL?
There is already a draft of the proposed Philippine National
Standard for Biodiesel which will soon be finalized.
In the U.S., there is already an ASTM D6751 standard
and in Europe, there is DIN 51606 and EN 14214 standards.
WILL THERE BE AN INCREASE IN DIESEL FUEL PRICE AS A RESULT
OF USING BIODIESEL BLENDS?
Reducing air pollution, particulary in the metropolitan
areas, will necessarily entail costs. This can be done by
either using cleaner fuel or improving engines or both.
Current petroleum diesel produced and sold by oil companies
has a relatively high boiling point at 388 C (industrial
diesel fuel), as compared to the 343 C (automotive diesel
fuel) produced prior to the oil crises in the 70s. The
oil companies can either adjust the oil refinery settings
or use additives like CME, both of which will of course,
incur additional costs. Initial studies indicate that the
use of CME will be more cost effective, will actually make
the diesel engine more efficient, will additionally
benefit the coconut industry, and will also help in the
country's effort to attain fuel security.
