Husq AB
new motor = 65.1 cc
3.91 kW = 5.24 HP
@10200 RPM (edit: 10200 was the emission test rpm used.  actual max kW rpm unknown).
engine family HVX
specifically EHVXS 0715AD
too many rpms for a blower or brush-cutter

more kW than 372
hair less than 576

-joe


3.91 kW = 5.24 hp(i) = 5.32 hp(m).

More kw than 372xp?  Ok, looks like .01 kW more - except the 372 number is more rounded off, so we don't really know.... ;D

Interesting anyway!

It could of course be for a non-xp version of the "572xp" - but if so it is a departure from how they did it with the 560 and 550 "families" ???

-don't know what power figures you are quoting, because they do vary between continents as you already know. 

-below you can also see that the power rating can change not only because of heated handles, seats and power steering as on the 576, but also between families as in the 395.
 
-the difference between the 395's is 0.68 kW = 0.91 HP.........quite the difference.
 
-would be easy to check the epa cert sticker on the saw to see what you are actually getting. 

my source epa gov, comparing apples to apples.

latest emissions certified motors

'new?' 65.1 cc ***engine family EHVXS 0715AD***3.91 kW
372xp? 70.7 cc**************EHVXS 0715AE***3.64 kW
576xp? 73.5 cc**************EHVXS 0745AB***3.61 kW
576xp? 73.5 cc**************EHVXS 0745AB***3.61 kW
576xp? 73.5 cc**************EHVXS 0745AC***4.04 kW
576xp? 73.5 cc**************EHVXS 0745AD***3.84 kW
390xp   87.9 cc**************EHVXS 0885AA***4.42 kW
395xp   93.6 cc**************EHVXS 0945AB***4.68 kW
395xp   93.6 cc**************EHVXS 0945AC***5.36 kW
3120xp 118.8cc**************EHVXS 1195AA***5.75 kW

-on a different note, it seems odd that all the stihl saws certified in late 2014 were made in Brazil.

Something obviously is up with those kW numbers - it doesn't look like they truely are max kW numbers. The rpm they were arrived at could well be a result of some EPA parameter, for all I know....


Stihl engines made in Brazil is nothing new, as far as I know - but I don't know if they all are made there.

downloaded older epa emission files from previous years.

the 65.1 cc is not a new motor family if i am reading the older year charts right?

the engine family EHVXS 0715AD dates going back to 2013, 2012, 2011.

the first letter seems to be the year.  A=2010; B=2011;.....and so on.

in 2011 was called BHVXS 0715D;  2012 = CHVXS 0715D;  2013 =  DHVXS 0715D;  2014 = EHVXS 0715AD

there is no explanation of the numbering system.  guessing here because the power level remained unchanged through the years.

from 2004 to 2010, the 65.1 cc motor has a completely different numbering system, 4HVXS 0655RB to AHVXS 0655AB along with lower power levels.

looks like 65.1 cc motor started with a saw called the "Husqvarna 265RX" ??

265RX is a brushcutter/clearing saw.  A heavy duty, overgrown weedeater.....

Weren't those forestry clearing saws of that Era based on chainsaw variants?   We had a 35cc clearing that was very Close to the 335xpt

I'll have to look in some of my older catalogs.  IIRC, the 265RX was still in the catalog as of 2003 or 2004.  Real beast.  The engine does look similar to a 2-series Husky (262XP, etc) IIRC.

As far as I know, it was a late version of the model 65 engine of the late 1960 and the 1970s. My brother likes to put Husky 77  top ends on those clearing saws.

They didn't disappear as early as 2004 here (the last OM was dated 2007). As I recall it, they were replaced by the 355.
