General Two Stroke Talk / Husqvarna X-torq two stroke engine! 4 stroke killer??? yes!
« on: January 16, 2010, 12:45:30 PM »
I know that KTM own Husky but I don't know about the chainsaw division... Look at the second video..no smoke at all...Really nice.. Yeah it is a chainsaw.. but the concept will probably give a 2 stroke rider a bit more torque/traction which is good.. The emissions is a lot reduced.. We are getting there!! 
NOW DEVELOPED BY HUSQVARNA WE HAVE 'X' TORQ.
'X' torq is a 2 stroke engine concept which gives you a 20% improvement in fuel consumptions, plus a 60% reduction in exhaust emissions.
Engine power can be measured in two ways. Brake horse power (B.H.P.). This is measured at the engines highest speed. Torq is measured at the engines speed where it has the greatest push.
Putting it simply, horse power is a 'punch' and torque is a 'push'.
Now to give a basic explanation of 'X'torq.
A disadvantage of 2 strokes is that the incoming fuel air mixture gets mixed up with the outgoing exhaust gasses. Fuel air mix can end up in the exhaust and wasted exhaust gasses can also be forced back into the engine cylinder, diluting the fuel air mix (caused by the exhaust pulse).
4 strokes don't have this problem as they waste (half) an engine revolution just to push out the exhaust gasses.
'X' torq engines have a porting system that during every engine revolution a shot of clean, cold oxygen rich air is introduced to the cylinder. This acts as a buffer between the incoming fuel air mixture and the outgoing exhaust gasses.
This separates the inlet gasses from the exhaust gasses. This with the 'super scavenging' front positioned ports gives probably the most efficient small 2 stroke so far made.
At full speed B.H.P. is the same. At lower speed the X torq motor out pulls a conventional 2 stroke.
The X torq concept has been used successfully for a few years now on certain Husqvarna machines, 335RX, 455 and 576XP.
The 576XP is a machine that in use can perform along with some 90cc saws. As the saw is reasonably compact and can be used for heavy, limbing with a short bar, then because of it's high torque motor is used also for felling with a long bar.
One saw for 2 jobs. A 30% saving in fuel consumption, a lot less to carry into the forest.
The now tried and tested X torq engines have now been introduced across a range of Husqvarna saws. 235, 235e, 240e, 435, 435e, 440e, 450e, 460e, 355RX and 576XP..

...Also include an oil cooler!! There is so much junk..not even funny! They used to put an isolation diaper under the gas tank before , the VP was evaporating/boiling because of the heat of the engine LOL. Black foot racing DNF a lot of times here(CMRC) lol..........Just junk. The sport is just total stupidity right now!
