direct injection, could this save our beloved 2 strokes?

[89sandman]

was reading my favorite flatlander mag supertrax, don't laugh i only read it for the articals, really! was talking about the new direct injection skidoo has. said most riders would only have to fill the res. once a season??!!! said smoke and smell were almost nonexistant. was 2012 compliant and was cleaner than the 4 strokes has anyone actually got to see one of these sleds in action. said 21mpg, WOW, i think they were talking about a 600 but thats some awesome fuel mileage right there i don't care who you are!!! with oil hitting $40 a gallon this sounds great to me. can't believe skidoo isn't pushing the advertising on this BIG time. the oil and fuel savings alone has really got my attention, cudos to brp for investing the coin to keep my 2 smoke a goin'...

i like supertrax.
if there is a demand (which there is)it will be figured out.

I've been around a direct injected sled for the last couple years. The University of Idaho put E-tec injectors on a Doo 600 SDI a couple years ago and has been fine tuning it ever since. Last year it won the SAE Clean Snowmobile Challenge. This year they had some problems modifying it to run on E85, but still got second place.

There is more information about this sled and the competition in general here:
http://www.mtukrc.org/snowmobile.htm

Short story though, on pump gas, we were putting out very close to stock hp, with emissions very close to National Park Standards, the best there is. It was very ridable with acceleration very much like stock.

It got 19.6 mpg over the 100 mile course, and was the lightest sled there by almost 100 lbs.

Anyway, I don't think the 2-stroke is going anywhere immediately.

They had a Demo around here (probably still does) I didn't get to check it out personally, but people that was around it was giving it two tumbs up.

This is good for the industry for people that still like two strokes. No smoke (they started it up in the shop for the FIRST time, and said literally NO smoke...)

And, after this years XP problems, I think Doo needs to step up again to get customers to buy their products.

I really hope it is as good as they say... Will push the four strokers even further, technology wise. Good to see some progress for two-strokers too...

It works on outboards

My 70HP nissan Outboard motor uses direct injection, It gets WAY better gas usage than my old Mercury 60HP, uses HARDLY any oil, burns really clean and has better emmisions than the similar HP 4 strokes. It definatley works, hope the snow manufactures go this way.

doesnt it suck that they pick on the smaller issues, like sleds, when theres these big pollutant cars and trucks out there that put out a million more times in pollutants than us sledders?

I don't think that this is so called getting picked on. But better MPG on a sled with less oil use would be freaking sweet.

BUT when we do get overly picked on, it's only because they don't want to attack something that pertains to themselves and is near and dear.

Might be worth noting that the only sleds to pass the emissions test were fourstrokes, no 2-strokes passed.

It is hard to compete with 4-stroke emissions, when you can take a 4-stroke motor, through a 3-way catalyst on it and lean it down a little and you are done.

 

[Idcatman3]

They had some problems this year, I'm not sure of the details. They did pass emissions last year, if you look at the 2007 results.

 

[SNOW JW]

I think it would be sweet if the new 2010 sleds all came with DFI.

 

[pinnedunderdoo#3]

the reason they go after sledders and other small groups like us is because they have a better chance taking us peasants down then a big air line company plus they use the planes to get to there next tree hugging fest faster...

Evinrude

I thought that was the reason BRP bought Evinrude is to get there direct injection technology. I thought we would see a whole lot more direct injection by now.

it all comes down to cost the fuel system is not cheap & the computer that runs the system is costly to replace if it goes down + it will be very hard to mod with it too.the fitch system is not the be all to end all very cool system & will help keep the 2strokes around, witch i think is good. but doo will make you think there is nothing better & thats far from it,its been around for quite a few years in boat motors & they definitely don't dominate the market.

It's real. This 2 stroke will be a lot cleaner than a lot of 4 strokes, but never cleaner than a "clean" 4 stroke. The Feds have set a limit on emission for 2012, and BRP has meet that requirement with a 2 Stroke. That's what matters.

Besides, I'll save $20 ever trip on oil and fuel, that'll go towards new electronics and injectors. Let's just say, I'm not chomping at the bit to be the "first" owner of a BRP 800cc Direct Injected motor. If they introduce it 2010, they will have the bugs worked out by 2012.

There's already rumblings of a tougher standard to follow 2012.

If you want to talk about dirty motors, look up bunker fuel powered cargo ships.

I have been saying this since 2000 when I got a DI 115HP evinrude outboard--at that time they ran cleaner than the 4 strokes, and had california approval as 4 star emmisions. They used less fuel than comparable 4 strokes with all levels of performance better than 4 strokes as well plus much lighter.
It is about time BRP moved this tech to sleds--the new E-Tech 2 stroke is awesome clean--Up at Steel Dreams last saturday they were running the 600DI E-Tech right in the showroom--NO smoke, No gas smell and quieter than a 4 stroke--could not beleive that was a 2 stroke they were running when I was on the other side of the showroom--figured it was the new 4 stroke---That new E-Tech will be the future of 2 strokes for sure.
You will see it on other machines as emmisions require them to do it--not untill then.

Would be nice if THEY had the bugs worked out on it and not leave it to the consumer to do it for them.....AGAIN Great idea I would get one for the wifey

finally something to ad and your banned, a 747 flying from new york to los angeles uses the amount of fuel that it takes to run 40 suvs for one year its a fact. so who is better served 400 people for one day or 40 families for one year. your on the right track go after the real abusers. look up this info and run it by your local greenie they instantly get defensive, they only like what the serria club tells them to like. its voting season [al gore for moron of the century]

 

[Linc]

Here's some startling facts.On a trip from Vancouver BC to Europe, the plane uses 17 liters per kilometer and produces over 6000 lbs or CO2,,,,,per person,and it deposits it in the worst possible place,,,up against the stratosphere.From the east coast to Europe it uses 220000 lbs of fuel and deposit 200 lbs soot from take off to cruising speed.

So Mr. Gore,try remember that when you're flying around the world trying to save the world ,,,,you're creating a carbon imprint that all the snowmobiles together,riding at once,can produce in a year!

In the words of Eminem "****k you Al Gore"

Here's a cool calculator. http://www.resurgence.org/carboncalculator/

If you want to know more about direct injection two strokes you can ask me im part of the U of I clean snowmobile, or you can come to boise snowmobile show or spokane snowmobile show we be at both.

 

[PowderGirl]

Great job on teh clean snowmobile guys!

Is this tecnology also being implemented by any dirt bike manufacturers yet? Thought I'd heard something about Yamaha coming out with something along these lines too.
