I've been playing with a Husky 445, and it took a while but it flashed on me how it works. The 445 had a separate air valve and port with a conventional carb, so it's easier to understand. What's going on is the extra air port flushes the exhaust out with fresh air, and that does 2 main things. 1 - it reduces intake contamination so the engine has a air-air/fuel mix in the cylinder instead of an exhaust-air/fuel mix. That helps improve combustion and power. 2 - it helps prevent raw air/fuel mix from being carried out the exhaust port - this is where the reduced pollution happens, as I understand it. I'm still learning this stuff myself, I'm from the days of loop charging outboards, which was essentially trying to produce a more pure intake charge by using excess air/fuel mix to push out the exhaust as a slug. I'm hoping to further the conversation here, and am totally open to other, possibly better explanations of this system, as I really want to understand it's minutia. It would seem to me, purer intake charge=more power, thus, this system may be hotroddable, albeit a bit harder to understand.
It is for epa. The air charge is designed to get between the exhaust and intake gasses as they are entering and leaving. The theory is that the fresh unfueled air leaks out at the end of the exhaust cycle instead of unburned intake charge.
Thank you for the tec on the saws my friend. Will continue to send prayers for you and the family. God bless yall and a special prayer for momma and son. ❤️🌲🪓👊🏻🙏
Morning Bellhopper hope you are having a great day today stay cool stay safe be kind 🙂 and I'm thinking of her and wishing her a speedy recovery and keeping her in my prayers as well.
Praying for y'all Bellhopper!! Keep you head up and keep doing what your doing!! Take care, love the ones you hold close and spend all the time you can with them!! Life is short and God is good!! Thank you and God Bless!!
Diesel engines use something like a strato. They have a hose that runs from the exhaust to the air filter. The exhaust has fins. That causes a vacuum and it pre pulls the larger dust particles off and blows them out the exhaust. Your adding clean air to the exhaust and let's the engine run better and cooler. When the exhaust goes out. Everything gets hot and runs bad .
Hang in there buddy, we all pullin for you guys! Definitely learned something in this video! It’s all way above my pay grade though! Take care and stay safe!💚🪓❤️

Good explanation buddy! That 372 xpxt cylinder looks like has a angry intake when the pist9n is init

Very good vid Hopper.
Morning Bellhopper hope you are having a great day today stay cool stay safe be kind 🙂 and I'm thinking of her and wishing her a speedy recovery and keeping her in my prayers as well.
Continued prayers for y’all and T glad rehab is doing well! 👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🙏🙏🙏🙏
I know Echo hasn’t went the way of strato yet, but they’ve changed the cylinder to meet epa regs.
Praying for y'all Bellhopper!! Keep you head up and keep doing what your doing!! Take care, love the ones you hold close and spend all the time you can with them!! Life is short and God is good!! Thank you and God Bless!!
You explain things well. So basically a stratto saw blows down with fresh air rather than a air fuel mix making it a greener saw so to speak.
Thanks Bell Hopper. Always excellent explanations.
I like more the old ones because i have a 372xp of 2001!
The carb on a stro saw is a little testy to adjust. The air pressure and humidity have a lot to do with it.
