4-cycle VS 2-cycle snowmobile engines

Post by est.. » Fri, 16 Oct 1998 04:00:00


I am new to this group and snowmobiles in general.  The question I have is;
are there any snowmobile manufacturers that make snowmobiles with 4-cycle
engines or are do they all use 2-cycle engines?  My email address is

There aren't any production 4-cycle snowmobiles in North Anerica - YET.  But
with all the noise and pollution regulations creeping up on us - who know.

Polaris has been doing some testing over in Europe of a 4-cycle snomobile
engine.  I believe (don't quote me on this) it is around 750cc and has in the
neighborhood of 80-85 horsepower.

I think it is safe to say that all indications are that 4 stroke engines aren't
far off the horizon.

Your probably right Chris...

But 80-85HP in 750cc's plus the added weight?  Thats the problem with 4
cycle.  Unfortunately the EPA will probably force it upon us at some point.
If it happens I expect Honda will probably be leading the pack, whether they
start producing sleds or just supply engines.  They have sort of been
leading the whole 4 stroke crusade with outbourds.

The only 4 stroke snowmobile is a Ski-Doo Mini-Z and it's only for kids.The
wieght and cold starting are the biggest problem.

I think four strokes will become little and more powerful.  Just look at the
new YZ bikes from Yamaha.  The bigger CC bikes are 4-strokes and are racing
quite competively against the two strokes from all manufacters.  They are about
the same weight and the power band is a lot more "user friendly."  I've also
heard that  Honda is going to competely quite producing two-strokes by the year
2002 (I think thats the year I heard).  So, I guess we'll wait and see.

Once again, I'd have to disagree with you Chris.  What I see on the
horizon is FICHT.  If you do a little research you'll find that this new
fuel injection system takes car of some of the load and a lot of the
emissions problems.  So I'm told, they are currently meeting California
and EPA emissions standards for the year 2006.  Or is it 2007?
Whatever, for a while anyway.  Sled, outboard and PWC manufacturers
don't want their products legislated out of business or performance
hindered likewise.  OMC currently owns the technology and has licensed
it out to Polaris and AC, so I'm told.  Tiger Sharks are supposed to be
coming out with this new FFI in 1999 or 2000.  OMC already has had great
success with it in their outboards.  That's what I see for the future.
Hope it becomes a reality.

There is no way a 4 stroke could be as powerful with everything else
being equal. Because of the way a 2 stroke works (the compression wave
echoing off the pipe), it forces in more fuel/air into the combustion
chamber, thus giving more power.
