Fogging engine out of water

[Catigale]

I haven't fogged a lawn motor in 40 years. I've never had a motor either seize or even use oil. It's probably a legacy practice that no manufacturer knows how to get the legal guys to clear the memo

[raycarlson]

i think you may be overly enamoured with technology and computers and can't see the tree for the forest.if your ignition is on and eng running you are burning fuel and your oil,if your motor is injecting extra oil then you are creating a gummy mess inside your block.If you have ever used a fogging oil you probably noticed its about the viscosity of wd-40 not 30W motor oil like your evinrude injects. also variable rate oil injection has been around on outboards for almost 30 years so BRP didn't invent anything new there.Tohutsu TLDI has had a more trouble free and just as efficent system at a more reasonable cost for fuel injection so no new magic was invented there either.all these systems are just mirroring auto technology by about a ten year lag time.and yes some things a human can just do better.

The auto fogging mod of the E-tec:
1) the engine runs at a fast idle to bring the internal temps to operating level
2) the direct inject oil is richer than normal but does not foul the plugs especially with X100 oil
3) the oil pump sends more oil directly to the internal bearing--crank, wrist pins. This system does not fill the crank case with excess oil like the old style 2 strokes because it recycles excess oil back to the oil reservoir
4) the fogging system turns the ignition off when the process is complete--2-3 mins depending on outside temps.

Why would you not use a system that is so easy You can do it on the trailer as you retrieve your boat and dump your ballast for the winter OR in your driveway. You can also opt out on fogging if you don't think there is any value to it--it has no effect on warranty one way or the other.

ECU controls oil pump distribution? This I gotta see....

[seahouse]

Thanks Bob, glad to see another technical person contribute.

I'll take this one -

You're kidding right. Again? Your sarcasm makes it look so.

As a point of fact, that's what the e-tec does, it distributes the oil directly to the lubrication points. The oil does not directly mix with the gas. It's what makes it beautiful.

This technology is all so new and hard to accept now, but I believe that the other manufacturers will have to adopt it. In 10 years this will be a widely accepted technology. Any new technology (note it's been around for several years already) always has its nay sayers when it is introduced, but at some point in time it will become the accepted norm. I would ask - what advantage is there to put that off?

[Catigale]

Sorry Brian, that was a bit snide...

My apologies.

I completely accept that this motor has a cool way to deliver an extra charge of oil to the pistons ring cylinder area

I would need a technical reference to be convinced that it can alter the delivery pressure and volume to the bearings.

All this being said, if I owned an ETEC I would certainly use this fogger every winter.

Actually, Detroit Diesel has been making 2-stroke diesel engines since the thirties (the venerable 71-series, I believe). Pressurized oil lubrication, like any other diesel. Noisy, in an annoying way, like bumble bees in a beer can. I'm not sorry to see them go. Lousy fuel efficiency, too, at least compared to current offerings, and not a hope of meeting EPA and CARB requirements (they're up to interim Tier IV, at this point, for smaller engines like under 500 hp - you can use the exhaust for breathing air practically).

I'm glad to see that the outboard manufacturers (well, one at least) have taken two-stoke technology to new levels. Makes me wonder if automotive applications are in the cards some day, or small engine like lawn and construction applications. High power-to-weight is always a good thing.

now i think your guessing at how your system works, no way can you have an oil pump with pressures high enough for direct injection, also delivering oil to open crank and rod roller bearings, through a drilled crank shaft,it just won't work.i don't know factually yet, but i'm betting your oil is delivered via your fuel injectors and not through an independant delivery system. i'll start looking for some tech data from BRP but if you have any tech schematics please post post them or at least some links to prove your correct, i would love to apologize and say i was wrong but i'm calling BS you don't know what your talking about,and are reading to much into BRP's shiny sales pamplets.

[Gazmn]

Come on guys, relax...

It's not a new invention of the wheel; just a new turn in the outboard industry
I'm glad that some have at least turned to being gracious. We who have bought E-tecs don't work for the company. While I couldn't tell you squat about what make the BRP Winterization process work, work it does. It was a feature that helped in my decision process to buy an E-tec; it's a short season here in the North East

And if it didn't work we would know by now - as the E-tec boards would be blowing up
I've had mine since '06. That, and all the X,$$$,$$$,$$$' BRP have put into "Their" technology would be a waste - & they'd be bankrupt...Again

Don't hate the player... Hate the game...

[Catigale]

..ive noticed that a number of ETEC users have suddenly stopped posting...hmmmmm

[Highlander]

Their all too busy [Group Hug everybody] in therapy I'd presume stroking their E-T

I heard u whined the prop-up clock-wise to get reverse & carry lots of spare rubber bands is that true !!

It’s all good fun, Cat.

Wha – You guys are making me do my (your?) homework again. It was years ago I did that.

Disclosure: I was about to jokingly post that I have no interest in the company, so I thought I better check the accuracy of that statement before I wrote it… Turns out I do have stock in the company! What are the odds? Doesn't change anything for me.

I started my original research when the ostensibly outrageous emission claims for this technology piqued my interest a few years ago. The EPA and CARB figures are very closely monitored by those governing bodies, and are difficult (maybe even impossible) to falsify. I could not see that the 2-stroke emissions could be so much better than a 4-stroke, but, as we now know, it was a data-based truth, and that truth has withstood the test of time for many years now.

For the past few years BRP has been opening a time window to boost sales in the off-season in which the warrantee (normally 3) is extended to 5 years, for free. I purchased during this time to get the 5-year warrantee. I post this for the more astute consumers out there following this thread and thinking of buying who might want to look into this, though it may or may not run outside Canada.

The following simple to follow info is what I could find quickly on the web. Here’s a link with visual aids for the fogging technology, as it applies to snowmobiles, specifically fast forward and refer to 1:12 and on. It shows how the oil lines run directly to the lubrication points, and run separated from the fuel injectors. I'm not sure exactly which details you guys are questioning, but looking at some of the videos down the side might provide some helpful info.

And guess what Cat? – I found an e-tec they made just for you here...

Ps. The BBD.B share price has tanked right now , but has been paying me monthly dividends for a long time !

This etec is beginning to sound like some type of NASA space probe. I am now quite certain that if it quits running I don't even have to bother opening the cover. It's too complicated to fix.

We used to just spray fogging oil into the carb intake until the motor quit. No carbs, they had to find another way to do it. Easiest way IMHO to deal with the whole fogging thing is to move some frickan place it doesn't snow. Then you can use the bloody thing 12 Months a year

I'm baffled why there's discussion about facts. Facts are easy to Goggle. According to this http://www.marineenginedigest.com/profi ... e/etec.htm which quotes BRP, the ETEC is not a traditional Ficht cycle two stroke: It does not mix oil and water--the oil is not delivered through the fuel injectors. Rather, the engine has direct oil injectors (not a single oil pump) all over the crank case that directly inject precisely controlled lubrication oil exactly when and where needed. Now this oil does of course wind up in combustion in any two stroke, but its in such small quantities that it's irrelevant. The direct oil injection is why the engine is self-fogging.
