Future of 2-strokes - A Comeback

[NitroTate]

For those of you who don't already know about this... Here is a little food for thought.

 

Everyone knows they "banned 2-strokes" however the fact of the matter is, they didn't really "Ban" them they increased the emissions standards so much that 2-strokes fell outside of the acceptable limits so the manufacturers then had to stop making them for the US.

 

With that said, there might still be a possibility that Yamaha (THIS IS NOT RUMOR, IT'S SIMPLY MY OPINION) could bring the 2-stroke banshee back in the US brand new and with better gas mileage and power while putting out HALF of the emissions of a 4-stroke.

 

If you aren't up on the newest technology of 2-stroke, I'll let you know.

 

Ski-Doo among other companies already have direct-injected 2-stroke motors for snowmobiles... could it come our way in the Banshee??

 

That would be pretty friggin cool if it did.

 

These motors wiegh less than 4-srokes (obviously), cheaper to produce, more powerful than 4-strokes, near half the emissions, and better fuel economy.

 

GM and Ford have already purchased the patents for this technology so they may actually be making 2-stroke vehicles soon too.

 

Incase you are interested I read this in SnowGoer magazine November 2008.

I think we should start something like a petition, and give it to Yamaha. Just a list of people that want to bring it back to the states. I have a friend that works for Yamaha Of America down in GA, in the marketing department. I'll ask her, and see about that.

i hope the shee comes back to the u.s and new and improved!

It would be cool but it wont happen.They have put to much time into 4 strokes now that they will not do any R&D on Banshee upgrades to let them sale them in the states again.

[locogato11283]

eh, i got a banshee. i dont care if they make anymore or not.

[shogs]

Also consider the fact that the banshee is so good because its so old and people know it inside and out. If Yamaha made a new banshee parts wont fit on a new one and people are going to have to start building new parts for them.

[Paddleboy]

if they do thats cool but i would never buy a new one for what they will charge. they have been made for 20 years and can come by for cheap. i'll worry about the new ones when they outlaw 2 strokes from the dunes. which is half of the toys out there so it wouldnt happen.

Yeah I agree with you guys, I would never buy a new one either and parts would be an issue until they become wide spread enough. But you gotta think, it's the same thing with all the new 4-strokes and their technology... there's no surplus of parts for them either but people are still buying them like crazy.

 

I think if emissions standards keep getting tighter and tighter they would invest in the research and technology regardless of what they are putting into 4-strokes. Remember, Yamaha really is pretty strong on the front of technology and usually first to market with the best of the best. AND they produce snowmobiles and watercraft too so they might already be tinkering around with this new 2-stroke tech.

there is a lot of new technology coming out for them. the small engine industry has been dealing with this a lot longer than people think. Briggs and straton has had injection available for lawn mowers since like 1972. but it has never been feasible due to the price of the unit. some of the lawn mower and turf industries are buying each other out for the 2 stroke engine technology. husquavarna {spelling} bought out red max for their strato charged 2 stroke technology. They couldn`t afford to develop their own so they bought the other company. stihl has a hybrid 2 four stroke called the four mix. It is basically a four stroke that you have to run premix in and the emissions results are great.it has increadible torque and revs pretty quick. The premix lubes the valves and everything. But the downfall is if you get a leak in the valve cover or any other area it could blow up the engine. that machine has given them enough epa emissions credits to keep selling some of their old equipment for a long time. For those that don`t know the epa gives these companies credits for clean running machines. That allows them to keep selling some of the older machines that don`t meet the emiissions requirements. I really don`t see the 2 strokes coming back as the epa still looks at the oil going being burned along with gas as a factor. 2 strokes still take oil in the transmission. so they look at it like they are using more oil than a 4 stroke does. by the time you put it in the trans and in the fuel for premix, its more than a 4 poke has in the engine.

As long as we are talking alternate 2 stroke tech, you don't have to burn oil in a 2-stroke.

You can have a standard wet sump, but require a supercharger. There were some Diesel direct injection 2-stroke engines with a wet sump.

ie. Detroit Diesel 6V-71. The only problem with those is they slobber oil all over the place. But they are a strong and reliable 2-Stroke engine.

an opposed piston 2 stroke has such high compression that it burns ALL of the charge..... photo-detenation. No emissions..... I don't think too many people have ever seen this type of engine, yet it is a clean burning 2 stroke.

 

until we murder all the oil big wigs.... we will never see the new engines of the 21st century

 

to me, this is a step in the right direction....a baby step..... I'm looking for that "giant leap for mankind"

 

 

+1 yet again for rotax!!!!
