Successful alternative fuels fulfill environmental and energy security needs
without sacrificing operating performance. Operationally, biodiesel
performs very similar to low sulfur diesel in terms of power, torque, and fuel
without major modification of engines or infrastructure.
Biodiesel offers similar power to diesel fuel. One of the major advantages of biodiesel is
the fact that it can be used in existing engines and fuel injection equipment with little
impact to operating performance. Biodiesel has a higher cetane number than U.S.
diesel fuel. In over 15 million miles of in-field demonstrations biodiesel showed similar
fuel consumption, horsepower, torque, and haulage rates as conventional diesel fuel.
Biodiesel provides significant lubricity improvement over petroleum diesel fuel. Lubricity
results of biodiesel and petroleum diesel using industry test methods indicate that there
is a marked improvement in lubricity when biodiesel is added to conventional diesel
fuel. Even biodiesel levels below 1 percent can provide up to a 65 percent increase in
lubricity in distillate fuels.
Compatibility of biodiesel with engine components. The recent switch to low sulfur
diesel fuel has caused most OEMs to switch to components suitable for use with
biodiesel, but users should contact their OEM for specific information. In general,
biodiesel will soften and degrade certain types of elastomers and natural rubber
compounds over time. Using high percent blends can impact fuel system components
(primarily fuel hoses and fuel pump seals), that contain elastomer compounds
incompatible with biodiesel. Manufacturers recommend that natural or butyl rubbers
not be allowed to come in contact with pure biodiesel. Biodiesel will lead to
degradation of these materials over time, although the effect is lessened with biodiesel
blends. If a fuel system does contain these materials and users wish to fuel with pure
biodiesel, replacement with compatible elastomers is recommended.
Biodiesel in cold weather. Cold weather can cloud and even gel any diesel fuel,
including biodiesel. Users of a 20 percent biodiesel blend will experience an increase
of the cold flow properties (cold filter plugging point, cloud point, pour point) of
approximately 3 to 5° Fahrenheit. Precautions employed for petroleum diesel are
needed for fueling with 20 percent blends. Neat (100 percent) biodiesel will gel faster
than petrodiesel in cold weather operations. Solutions for winter operability with neat
biodiesel are much the same as that for low-sulfur #2 diesel (i.e., blending with #1
diesel, utilization of fuel heaters, and storage of the vehicle in or near a building).
These same solutions work well with biodiesel blends, as do the use of cold flow
improvement additives.

BLT : Bantuan Langsung Tunai ( Direct Cash Assistance)
Open letter to Mr. President SBY Assalamualaikum wr.wb In connection with the distribution of BLT planned early this month. Our whole community is the Village Jatimulyo thankless us to Mr. Presiden.BLT will be distributed to 222 families. Behind the gratitude there is little that we ganjalan natural village as the Government, Mr. President .. To know Jatimulyo Village, District Wedarijaksa, Pati regency, Central Java, has a population of 2335 inhabitants is 698 KK tentram the village where the majority of the population derive in the main agricultural sector (read: farmers) with the human resources level is very simple., harmonious and peaceful. I led the Village Jatimulyo exactly 1 year mid-March and this is one of the most youthful of the 400 head because the Village was still the age of 28 years. Although I am still young as the Village Head of approaches to try to give what the needs, aspirations and expectations and provide solutions for the problems people Saya.Dari various things that we can not pecahkan problem is BLT (Direct Cash Assistance). Peaceful community that is full tolerance, with the BLT we feel there is a change in the social. The life of a neighbor memenci change into each other and mutual distrust. BLT data that is not in the Government of entry before I become a conflict when horizaontal BLT is years down yesterday and will go down again month - this month. Mr. President that we respect, to know that Mr. BPS data from the less accurate and not right and when the agency head on the record to say we comply with 14 criteria listed in very poor conditions of the population impossible for us to be able to do it especially diembel - embroider with the target data. Then I started thinking about how when bijaksananya BLT funds for the program has become PNPM program or PPIP program or another for many kemaslahatan community does not become bantua individuals. Mr. President that we love very, Village Jatimulyo have never got anything from the program unless the government funds that is not how ADD. Bondo our knowledgeable Deso not more than 1.5 Ha if the auction to pay for the Village administration for 1 (one) year is not even enough. And we only rely on self-reliance from the public .. if the BLT makes our society can no longer harmonious. Then we can with what we built the Village? With all humility I as the Village Head, the village is the smallest of which is the foundation of the State is seeking the policy of Mr. President to be able to make the program a more capable without the need to ram one with the Society lainnya.Kami want to pursue self-sufficient farming for which Mr. President dengungkan. In closing, we say thank you and sorry to the request of Mr. President, when we submit the less well, Wassalamualaikum wr.wb.
Sincerely,
The Village Jatimulyo
