Idea: The Rainbow CCV filter?

KeighJeigh · **Posted:** Thu Jan 08, 2009 6:18 am

I have yet to see this considered in the many discussions concerning Provents and other CCV scrubbers:

Has anyone seen how the old Rainbow (and some other models) work? They take incoming dirty air and then run it through water. As the bubbles make it up through the water they are scrubbed of debris. The system works quite well.

Why not the same thing for the CRD:

An enclosed jar about 3/4 filled with water with a bit of antifreeze. The vent tube from the engine runs down to the bottom and is submerged in the fluid. The exit from the jar is at the top at the level of the lid out of the water. At the bottom is a plate with holes to break up the bubbles into smaller ones. I suppose you could but a pot scrubber in there as well. The actual amount of air coming out of the vent tube is fairly low so I don't think the jar would have to be very big for it to work well.

When the jar gets full of oil and gunk, just simply empty it and refill. No "filter" needed and possibly a very effective device.

Thoughts?

Too much idle time in your schedule....... :wink:

I saw something like that at college. It held a gallon of water and four people could use it at once. Never heard it called a 'Rainbow' though...

Where ya gonna pour the petroleum-polluted water, hah? Down the drain? Does Valdez stir any memories? :shock:

Yes, I considered that and I do have a solution. I just haven't figured out what it is yet.
But, then again, oil floats on water so it might be fairly straightforward to simply pour it off and add it to the oil you take to recycling after an oil change.
I'll let you come up with a solution!

But beyond the toxic waste issue, I wonder if the concept would actually work?

(Maybe it could be called the Bongvent Filter?)

It would work if you can contain the water without losing it due to splashing or evaporation, and if you can guarantee you won't accidentally suck it into your engine.

Where does the petroleum pollution go with the EHM?

The stock CCV setup is used in millions of vehicles with little trouble.

Water injection with a little extra hydrocarbon boost.

One of the reasons I thought it might work is because there is a relatively small volume of air moving through that hose. I don't think it would be sucked into the engine if it were designed properly.

Into the air. The stock unit passes too much oil into the intake. A better solution is a filter that passes the blowby back into the intake and separates the liquid for later disposal with the engine oil. Oh, they only made 20k or so of the CRDs.

....will do what you want without the water, just stuff it with poly fill or as I did Coarse Steel Wool. Oil wet strands trap more oil and it goes to the bottom to be either drained back to the pan or drained to the oil disposal bucket.
My employer makes oil separation from water equipment, I don't think it will fit under your hood.

concerning the oil on top of the water.

There is an oil absorbent product on the market made from dried peat moss. Floats on top of water and will absorb the oil. All you would have to do is pour some on top of the oil let it be absorbed and the skim it off. Good to go. I believe it is call Absorbit or something like that. It has been used in remediation of hydrocarbon contaminated ground water.

Oh and you can burn the oil contaminated peat moss to get rid of it.

Not exactly 20K. They made lots of them before 2005 and still make them, just not for North America. Not sure if they strip the CCV off the export models though.

My point went right over your head UFO. It's a pollution problem when it's mixed with water, but blowing it out into the air is fine?

Our CCV setup is used on OTHER vehicles like, for example, the millions of Powerstroke Diesels on the road.

I have NEVER advocated the elephant hose. I told you what I did, and it doesn't go into the air.

And most CCV filters actually filter the oil before burning the blowby.

Cool idea!
This is beginning to come together. The top, lose absorbent material could also be a final filtration for the air bubbling up through the liquid. Although, in reality I guess you would only need a bit of it in there to absorb - perhaps some replaceable pellets.

NOTE: I checked my Sakamuchi (?) filter today after about 5K miles. All I drained out of it was a few globs of thick goo and about 2 tbs of water. I was not expecting that because the filter I put on the end of my elephant hose experiment caught quite a bit of gunk in less miles.....and no water. (although I suppose it could have evaporated since it was vented)

Idea: The Rainbow CCV filter?
