TWIN TURBOS Cox 049

A small step beyond a generator to a “turbo” powered engine!  This is happening on Warren Leadbeatter’s  Facebook page:

My bad, maybe it’s only one. I guessed they were stacked on top of each other, but it must be a single turbo on the intake.
Well, it is still in the engineering design stage.

This is marvellous...of the 2 volute casings one is the turbine driven by the exhaust gases and the other is the compressor delivering compressed air to the carb. This would only make sense with the exhaust gases channeled right into the turbine to drive it, and with non-SPI cylinder to retain the pressurized fuel-air mixture in the crankcase.

Novelty and real cool

But for a REED valve engine.... if the Turbo works as one should
I think the inlet pressure would just float the reed off the seat all the time always over coming crank case pulse for seating

On a rotary valve 2 stroke...a turbo would be way cool

Down side, if one did work, is way over reving the engine...have to be careful to have a good load

I can over rev a TeeDee .049 "on bench" destruction very easily -----normally aspirated

Awww, you guys are all to polite and kind. The yahoo’s on FB used a lot of four letter words in their comments! It may not be physically or engineered to be possible, but the picture is worth a “ Hey! That looks cool! “

I think that is as cool as can be! If he wants to stick with a bee type engine and make it functional then I bet a rotary drive coupled with a pressurized fuel system could possibly produce some really good results, maybe, hopefully. Either way, it is still cool as hell!!

Yes Ibelieve the issue is how to make the engine suck fuel with the pressure around the spraybar now maybe higher than atmospheric....a pressurized tank. Whether the reed floats even after the suction may not even matter as long as the crankcase is pressurized with fuel-air mixture. Hence the non-SPI design required.
