Pet peeve: "clean diesel" greenwashing

[ron]

smog is one of the reasons we exported the mfg else where old tele man. In the orient the where masks too keep from getting sick ,GERMS, they are packed so tight, billions and billions. Ecomodded, isnt bio diesel kind of a man made(converted)hydrocarbon

My, my...the depths to which this thread has descended.

ain't it the truth

All I'd like to add is we just got our first tier 4 compliant engine at work today (off road equipment hasn't had to meet tier 4 until recently), a 9.3L CAT engine. All I can say is WOW, emissions equipment is all over the place and looks quite complex. The particulate filter is as big as the muffler, and the heater to keep it warm is just rediculous.

Edit: wow, just noticed that is only tier 4 interm, not even tier 4 final

Its more the other way arround. The environmental (and other) regulations increased costs, we demand cheap products, many Asian contries dont have anywhere as high labor and regulation costs, so companies move manufacturing to where it costs less even with transporting the goods half way arround the world.

Once they start demanding better pay, better air, better everything the cost of producing in their countries will come up bringing manufacturing back here. Or we can spend the extra on made in USA.

Yeah that "heater" is a burner that burns fuel for no other reason other than to get/keep the aftertreatment warm. I knew some folks who referred to them as "flametrowers"--which is basically what they are.

Here is a link to a pdf file on the differences between green diesel and biodiesel, if anyone is interested.

...the table on page 8, "Diesel Fuel Properties," would seem to condemn "biodiesel" for its lower energy density, 38 MJ/kg versus 43 MJ/kg for Petrodiesel?

...but, conversely, biodiesel's better lubricity (than Petrodiesel or Renewable Diesel) should mean longer injector and pump lives.

[ecomodded]

They should adjust the price of BIO diesel to match its BTU's.
Its not like we are buying it for its flavor.
I wonder why they do not add lubrication/oil to the "Green/renewable diesel" to bring it up to the lubricity of biodiesel,it would help with its reputation or lack there of.

...that brings up the question: just HOW MUCH 'total' energy does each of the man-made diesel fuels *use* to create a gallon of fuel?

Obviously, one is less costly than the other(s)--petrodiesel--because "Mother Nature" invested energy "into" the original biomasses over millions of years.
