Re: [Biofuel] Injector pumps Jetta TDI

2014-01-30 Thread jan-anders.warnqvist
Hello all, this alerts an alarm in my backbone. I suppose that we are 
talking about a pump of distributor type here ? Well, these pumps are 
certainly sensitive to viscosity and even more to abresive metal salts , 
Always present in SVO. These two concerns are covering the facts that 
the Jetta runs well on (washed) biodiesel. For using SVO as a fuel I 
would recommend a motor with a  different pump design, similar to those 
of W123-124 Mercedes-Benz. These pumps are not very tolerating of metal 
salts, but at least they should last longer than the distribution 
pumps.but the best way is to make sure that the SVO are pre-treated in 
terms of contaminations, even as in small amounts.

What year of TDI?  We ran a '99 TDI on  biodiesel for a long time

issues.  I'm not sure that I'd run SVO on the TDI pumps, but 
biodiesel
should not be an issue.  I've found that many diesel mechanics have 
what
could best be called an allergic reaction to biodiesel, and blame it 
for
all sorts of engine problems.  One blamed SVO for an old mercedes 
being
slow claiming that it had ruined the car... and it was only properly 
heated
180degree SVO in this particular one too.  I suspect that it was 
having a
non turbo 65 horsepower engine in a 3500lb car at 9,000 feet 
elevation that
made it slow, myself.   I do know that some injector pumps are 
not
particularly strong (I've heard that the lucas ones are on this list, 
but
not sure of others), and could be affected by a fuel with higher 
viscosity.
  So, perhaps... but I had not heard issues with the early TDI's 
before.  I
have heard that the PD TDI's may have issues with polymerization, 
depending

on the iodine number of the biodiesel.

SVO
could be used in a Jetta. I bought my Jetta with the expressed

use biofuel but it because difficult because most of the sources of
vegetable oil dried up so I just wound up using regular diesel.  
Anyway
recently my injector pump broke and needed to be replaced. My repair

the

to replace them too often. I would like to hear comments on this. Is

any truth to this. After about a month my repair guy managed to find 
a used

one in North Carolina.

[Biofuel] Time for Big Oil to Pay for Its Pollution

Time for Big Oil to Pay for Its Pollution

Thursday, 30 January 2014 16:07
By The Daily Take, The Thom Hartmann Program | Op-Ed

We need a carbon tax, and we need it now.

During his State of the Union Address on Tuesday, President Obama talked 
a lot about climate change, and how important it is that we stop using 
19th century energy forms and start using 21st century sources of energy.


The President said that, Over the past eight years, the United States 
has reduced our total carbon pollution more than any other nation on 
Earth. But we have to act with more urgency – because a changing climate 
is already harming western communities struggling with drought, and 
coastal cities dealing with floods.


He went on to say that, Climate change is a fact. And when our 
children's children look us in the eye and ask if we did all we could to 
leave them a safer, more stable world, with new sources of energy, I 
want us to be able to say yes, we did.


President Obama specifically addressed carbon pollution, saying that he 
had directed his administration to start working more with states to set 
new standards for the levels of carbon pollution that can be pumped into 
our skies.


While that's a good start, we need to be taking more definitive steps to 
curb carbon pollution associated with burning fossil fuels that causes a 
whole bunch of problems in addition to climate change.


When fossil-fuel based carbon pollution first became a talking point, we 
learned about how bad the health effects of air pollution were.


Then, we learned about the health ailments it can cause, things like 
lung cancer and asthma and heart disease.


And most recently, we learned that carbon pollution from burning fossil 
fuels is drastically altering our environment, driving global warming, 
and contributing to more severe weather across the globe.


But while we have learned more and more about the effects of carbon 
pollution, not once have we asked the fossil fuel industry and other 
carbon emitters to pay to clean up their waste.


Instead, we have been footing the bill.

The fossil fuel industry is the only industry that doesn't pay to clean 
up its own waste.


Instead, they profit of off the negative externalities - that waste - 
that comes with our nation's addiction to 19th century fossil fuels.


Externalities reduce the costs of business for a corporation, which 
means increased profits.


So, the fossil fuel industry will do anything to protect these 
externalities, because it means that they can dump their trash (carbon 
dioxide) on you and me without having to pay a dime for it, all the 
while seeing their profits skyrocket.


A recent study by the TEEB for Business Coalition found that globally, 
the top 100 environmental externalities cost the world-wide economy 
nearly $4.7 trillion each year.


That $4.7 trillion includes the costs of greenhouse gas emissions, the 
depletion of natural resources, the costs of climate change, the costs 
of cleaning up from climate-change driven severe weather events, and the 
costs of pollution-related health problems.


In fact, back in 2013, researchers in Europe released two separate 
studies, that revealed that fossil fuel-based carbon pollution can 
directly cause lung cancer, and can even worsen heart conditions and 
heart failure.


And countless other studies have detailed fossil fuel-driven carbon 
pollution's role in driving up cases of asthma and other health issues.


Right now, the fossil fuel industry has no incentive to change its ways. 
No incentive to stop flooding our skies with pollution, and no incentive 
to stop profiting off their negative externalities.


And to make matters worse, we are funding the fossil fuel industry's 
polluting ways.


Because of our out-of-whack tax policies, we are forking over more than 
$4 billion each year in subsidies to the fossil fuel industry.


And when you're getting $4 billion each year from the government, 
there's not much incentive to change what you're doing.


In his speech on Tuesday, President Obama called for end to those 
subsidies for Big Oil, saying, Let's continue that progress with a 
smarter tax policy that stops giving $4 billion a year to fossil fuel 
industries that don't need it, so that we can invest more in fuels of 
the future that do.


But while we're closing tax loopholes and cutting off subsidies to Big 
Oil, let's have that industry pay for the costs of its pollution with a 
carbon tax.


As soon as a carbon tax is introduced, not only will carbon pollution 
decrease, but all of the clean and green energy alternatives to fossil 
fuels will become economically viable, because fossil fuels will be more 
expensive to produce.


Carbon taxes are already popular over in Europe.

Sweden for example charges $150 per ton of carbon pollution dumped into 
the skies, and it's working wonders to decrease carbon
