Just a (not so) subtle reminder that your political views are not allowed on CF. Feel free to discuss the topic, however if you add politics don't be surprised if your post disappears.

Re: Diesel smoke now considered to cause cancer
Might be urban myth but I read that the reason RVs have a huge sticker that says "Cruise control does not drive this vehicle" or something along those lines is because some idiot got mangled after engaging cruise control then heading back to make something in the kitchen....
Wouldn't surprise me if it was true though.
I've read a few health stories this week. Smoking and drinking doesn't affect male fertility, fish oils don't help dementia, now this about fumes. Pretty much everything can cause cancer, even oral sex.
I gave up listening to these studies/advisories years ago. Sailing may cause drowning :-)

Re: Diesel smoke now considered to cause cancer
On the old diesel trucks that have mechanical injection, exhaust does have some black smoke at full power. Most sailboats with diesels still have mechanical injection. How much black exhaust do folks see? I am thinking the wet exhausts on diesel engines in sailboats give a good scrubbing of particulates and contaminants that cause cancer?

Re: Diesel smoke now considered to cause cancer
Diesel fumes also make people sick on boats.
The smell of diesel on a sailboat, should be better than a powerboat.
I have a gasoline power boat 37 foot, and I dont smell anything.
adding that I have these hard rubber exhaust downturns that force a lot of the exhaust under the water. they are sealed to the transom and do have a small hole to prevent reverse siphoning.

Re: Diesel smoke now considered to cause cancer
What I have are these and they were made decades ago and still work well today.
Patent number is 3162171
The only info I could find was the patent number and nicely the patent office has all the relevant data .

Re: Diesel smoke now considered to cause cancer
Diesel engines do make particulates and they do cause cancer. US-EPA is in the middle of a program to reduce diesel particulates for road and off-road engines. Many trucks now have ceramic filters which capture and burn the soot, sort of like catalytic converters on cars finish off combustion (but a different process).
Diesel engines operate by changing the amount of fuel injected per stroke, for a fixed amount of air. At the point of maximum power more fuel is injected than can be completely burned so you get soot particles.
Just back off the power and the exhaust will clean up, and you will operate in a more efficient range. Your 40 horse will be clean if you treat it as a 20 horse engine.

Re: Diesel smoke now considered to cause cancer
I saved the relevant patent pictures so people can see what this looks like.
Mine are modified a little to be slightly shorter and are cut at an angle.
these have worked out well to keep the fumes out of the boat.

Re: Diesel smoke now considered to cause cancer
I'm not saying breathing carbon dust is good for you, but if diesel fumes were so bad wouldn't we be seeing a lot more cancers in places like power plants, and mechanic shops?
Anything that gets in the lungs will cause irritation, and eventually cancer. The preservatives, and other chemicals, (pesticide residues), in food also cause cancer.
It isn't that carbon, (we are made out of it), is bad it is that is carries other chemicals deep into the lungs, where it mixes with tobacco smoke, and other things we breath.
But yet again, they won't shut down coal plants, or diesel trucks or trains, because they have too much political power, they'll just add more regs to boats.

Re: Diesel smoke now considered to cause cancer
A company still sells something similar
Fresh Air Exhaust reduces boat exhaust noise and carbon monoxide
I think you can come up with your own design.
use a rubber pipe adapter as from HD. they come in bends and flow well made for sewers and are designed to join pipes together.
Or even a large formed rubber hose as used for radiators.
I am thinking of doing this for the generator exhaust, sending it underwater. It does create a gurgling noise but most of the fumes are gone.
When I installed the underwater extensions, I added a long piece of small translucent poly tubing like 1/4 or 5/16 inch shunted from the raw water flow that exits right at the transom. I did this to make sure I see the cooling water flows out the exhaust.

Re: Diesel smoke now considered to cause cancer
They are regulating diesel trucks, trains and coal plants, off road farm equipment too. My business in emissions test equipment to engine manufacturers is good. They won't make you retrofit, but your next new engine will be cleaner (and more expensive too).
The arguement of does soot cause cancer is over, yes it does. Not as much as some things, more than others. Now that more dangerous sources are on the wane, the regulators can focus on statisitcally smaller and smaller cancer sources.
Maybe eventually we will all die of "natural causes"

Re: Diesel smoke now considered to cause cancer
Everything is causing something: sigarettes cancer, alcohol addiction, sweets, pasta, bread, air......is there anything else they can toss us. Live life and stop worrying so much....life it too short already. I am not saying " go suck on a truck exhaust" but at the same time enjoy life and don't worry too much.
My grandfather smoked, drank til he died at almos 90 yers old a very happy man.
I say, drink in moderation, smoke your pipe and go sailing....

My father smoked and drank moderately all his life, he died at 72 from lung cancer. Suggesting people will live long lives while smoking is nonsense. There ARE things that accelerate your death, smoking is one of them.

Re: Diesel smoke now considered to cause cancer
I am not suggesting that smoking is good for you or it will make you live longer. I am just saying that we can't go crazy and worrying about everything, to me everything in moderation is OK.Everything we eat, we drink and the air we breathe has something in it that is bad for you, for heavens sake people eat at the golden arches without asking themselves " what's in there" or they pick up some nuke ready food and there you go.....who knows...
Just my thought
