Thread: supercharging a 2 stroke

I wouldn't have even bothered taking the muffler off. It was sitting in the junk pile with a busted, uh, whatever the heck the string thingy is. The customer didn't want to spend $70 fixing his $59 weed wacker. My brother started it up and said "check this out", and blasted it with a blow gun. It sounded COOOOOOL, so we played with it until it didn't work NO MO.

Al, that sounds like an add for a hooker not a pipefitter!

Well,Mr Pipefitter just where do you think I first heard that term? It certainly was not from the director of the church choir .An old terbacker chewin fitter during a refinery shutdown many moons ago laid those words of wit on me.

it was off full metal jacket in the '80s

the experience everyone has is that changing pipes doesn't help.

physically turning the compressor eats horsepower that cant be put back.

Prove me wrong!!!

I don't understand how you think ANY engine can ge 100% efficient.......let alone more than 100%. This would be beyond perpetual motion, which as we all know is impossible. What about energy losses through drag or friction, heat, gravity, and so on?

Hi,

in years gone by I really enjoyed using 2 stroke supercharged diesel engines, these really strange things with 12 pistons in 6 cylinders, fuel injection and a roots compressor.

I can't see either turbo or superchargers working well on the type of 2 stroke engine found in chainsaws though.

Bye

I dig this new 3 cyl, 6 piston, twin crank diesel.

Hi,

we had a similar engine (6 piston, 3 cylinder) as a generator next to the big 12 piston, 6 cylinder engine. Two stroke supercharged diesels are fun! Until they break...
