Why ?
All you are doing is taking away all the advantages of a two stroke, namely simplicity and lack of weight and complexity.
Stratified air injection is being used in two strokes to clean up emission's, as are catalytic converters.
Strato engines generally use an extra butterfly and 'transfer' ports to inject fresh air ahead of the incoming transfer charge, this sweeps the exhaust out of the cylinder rather than the incoming charge, significantly reducing the amount of mix lost out the exhaust and significantly reducing emissions.
Major part of the heart and soul of AULRO.comIt reminded me of the old Commer Knocker TS3 engine.

A great little engine and there is the nub of the matter, little. Far too little displacement to make real horsepower. I was once quite familiar with them. Wall and Co. in Winton had eight of them at one time. Commer Knockers were a great eight ton body truck but not a great prime mover, not enough power, even though many of them were used as prime movers. You did not want to be in a hurry if you had a bogie trailer and 17 tons of freight on one. Likewise with sheep crates and often a dog trailer with sheep crates. The wind resistance of these things is horrific and plugging across the plains into a strong headwind imbued drivers with a modicum of patience. Add a pair of cylinders, more bore and stroke and the knocker may have survived twenty years or more longer.

Major part of the heart and soul of AULRO.comI agree about them being slow as a prime mover/trailer. Going up Razorback behind one was simply awful!

They had a distinctive snort-snort-snort sound. One wheat season in the ealry sixties we and others had been carting into the Allora depot and were all gathered in the Commercial after a days work when the sound of a knocker hard at it was heard when the truck came over the crest at Glengallan some miles away. The exhaust system came adrift in front of the first muffler, too hot to fix so he just kept coming in to beer time. Deafened him for quite some time after he shut down. Bloddy loud without mufflers.
I much preferred the sound of Detroit 6V71N or 12V71N. They had a real crackle.

Try sitting in one on a hot day somewhere like the old Burringbar pull in the North of NSW. You nursed every rev to hit the bottom flat out to get a good go at the climb and by Murphy's Law, it seemed every time there was some ****** caravanner dawdling along admiring the view and forcing you down into the bottom of the box for a long hot drag up the hill at not much more than walking pace.

That is a poor recording. It gets blower and fan noise but not the exhaust note. Looks like the engine is on a dyno. and the exhausts are probably 4 metres away up in the air. Odd looking engine variant, has the later model cast rocker covers but the tag on the engine says it is a two valve which is an old, old, engine.
