Engine 600 arctic cat

Knock Sensor: An engine knock sensor detects detonation due to fuel octane, quality and/or ethanol content. Based on information from the knock sensor, the engine management system adjusts ignition timing and fuel delivery for optimum performance and combustion. If fuel quality is such that the combination of reduced engine timing and a richer fuel/air mixture can’t prevent detonation, the engine goes into safe mode until fuel quality improves.

The engine is designed for 91 octane fuel.


New cylinder port timings and shapes are matched by new cylinder head and combustion chamber shapes for optimized efficiency and performance.


Air-Only Throttle Bodies: Two 47-mm new-generation throttle bodies flow air into the crankcase. In addition to flowing only air (and not fuel), these throttle bodies are shorter and lighter than those used with previous engines.


Sealed pump shaft: The center water pump drive shaftis sealed in an oil bath for optimal lubrication, reducing oil consumption.


Double-V Reed Cages: Two double-V-shaped reed cageswith 4-petal reeds optimize air flow into the engine.


APV Exhaust Valves: The Arctic Power Valve (APV) exhaust valve system features a new, Arctic Cat designed valve design. The multi-stage valve movement is controlled electronically by the engine management system and works in concert with pipe temperature, ignition timing and fuel/air delivery for optimized performance and efficiency in all conditions.


EPTS: Designed and patented by Arctic Cat, the Exhaust Pipe Temperature Sensor (EPTS) system uses pipe temperature information as an input for the engine management system, helping to control fuel/air delivery, ignition timing and the APV valve opening.

Nice write-up, John.
The best feature of this engine is the background knowledge that went into it. Greg, Donn and the rest of the guys have sooo much experience with 2 strokes and this is a great example of pushing 2 stroke technology forward when no one else is trying. Low pressure injectors giving DI emissions and performance, I guarntee the other guys are jealous. I want one! Congrats guys, your hard work shows!

I just read about an engine design that, in my eyes, continues the legendary performance of the lay down designed engines. Great snowmobile engines built here in MN! Awesome! The details within this design, tells me the snowmobile engine design group addressed all the key design points and knocked this one out of the park! These guys know how to design a performance snowmobile engine. Can't wait to ride one! I just may have to get a 2 stroker again, someday! It's nice to have options!

Sounds like Arctic Cat really did their homework with this new engine. Hopefully it proves to be reliable in the real world. Plus on a personal level I'm glad they brought back both the ZR and El Tigre namesakes. Loved our 1990 El Tigre!

Oh Boy, do I see the 800 getting the same treatment next year? Fingers are crossed!!!

Very nice write-up about some really interesting stuff. I'm so glad they brought back the el Tigre 6000 name (imho it should not include "ZR")... To me, that is THE most nostalgic sled ever built. BTW - I also like the ZR nomenclature on the remaining lineup.
The move to a 137" slide-action skid (and the new 4 stroke) for part of the lineup was also long overdue. Both are VERY good moves.

It would be really nice to see some youtube footage containing sound clips from this engine. Curious to see what it sounds like.

Thumbs up all the way Fella's. You guys really outdid yourselves this time.

What is the function of redundent rings on the piston heads , higher compression ?

Krom says:

All consumer arctic cat 2 strokes use 2 piston rings per cylinder, for many reasons
