Arguing the above is like arguing that silicosis isn't caused by silica dust, black lung disease isn't caused by coal dust, and snorting asbestos does the lungs a favor.

Polyaromatic Hydrocarbons (PAHs) are carcenogenic. Much study has went into figuring out what chemical structures actually compose soot particles. PAHs are among them. Tiny particles are especially bad because they can penetrate very deeply in the lungs and become irreversibly embedded. People with lung problems and asthmatics are especially sensitive. The CARB dudes aren't the ones who came up with this.

We do need organizations like CARB, but we need those organizations to be reasonable in determining what kinds of regulations are needed and enforcing reasonable methods of implementing them.

Ah but I beg to differ- those bad for the lung particles are also made up of less than PM10 matter like gasser exhaust. They (particles) may in fact be the responsibility of certain lung ailments but there are credible studies out there that in major metro areas ( metro LA e. g.) that only 7% of this type of VOC is sourced from the total diesel output of the area.

7%!!

That's 93% of this cancer causing stuff is non diesel in origin.

That total diesel output includes big rigs, industrial applications, nearby ships at sea, etc. Our light diesels therefore make up a very, very small amount of that total!

The problem is through these quacks like Dr. Tran, that CARB determines if the stuff can be seen then it is bad- you do not see less than PM10. that's 93%! And therefore make our light car diesels subject to absurd testing (in CA).

Again is CARB Good??

...I wasn't specifically referring to diesel particulates. Any soot particles containing PAHs are bad. It doesn't matter at the source is. I'm surprised that only 7% comes from diesel exhaust. The ones you can't see are the worst in terms of health effects. Diesels have that "black plume out the exhaust stack or tailpipe" stigma that makes people look to them first.

I hope to see more diesels out there in the future. I love mine. But I'm not a stick my head in the sand type of guy when it comes to environmental concerns. In an ideal world, they would be able to tune the engine to burn everything as completely as possible and have a non-urea based catalyst bed to knock-out the NOx and chuck the EGR valve. We're not there yet.

Carb is like everything related to the govenment. it is created ot designed to do good for the many. Along the way things get messed up.

in general carb is pushing for cleaner air and less polution. Do they mess up? yeah.

I can not say they are all the blame for diesel not being more comman here. public opinion and what they know of old skool diesel technology is to blame. that and the media car makers here and CARB limiting diesel adds to that idea living on. Americans think diesel is slow, dirty, and noisey not clean powerful and efficent like modern diesel engines can be.

today I went to autozone to get an 8mm hex key to change my oil. I had already changed my fuel filter. I knew a guy that worked there, he used to work where I do. he asked me what I was breaking today I said changing the oil in my jeep. he said wow you work on your own car that must be a sight. I said no I'm not so bad if I have the right tools.. I already changed out my fuel filter, the only thing that stinks is me.. I smell like diesel. he said "oh a diesel jeep that must be awlfull. why would you want to drive that?". I told him it was actually very nice, powerful and efficient. that I can get 27 MPG on the highway and thats doing 75 or faster in it. he did not know what to say after that.

Its all what the public is told to think about diesel.

BTW
I love the TV ad Audi has for clean diesel. showing all the barrels of oil going back on the ship. they clain if 1/3 of all US drivers drove clean diesel cars we could send 1.5 million barrels of imported oil a day back, to me that is giving OPEC the finger.

They're trying to remove the 'California' part and just be known as the Air Resources Board.

I got an e-mail across my desk recently about ARB and got all excited until I realized it wasn't about bumpers or winches, but the agency formerly known as CARB.
