Does anyone know of a supercharger that fits a two stroke 50cc engine? Any recomendations?
I remember eating the Triumph Matisse at the hairpin in practice on my tiddler. Hee hee !! -- Ed Light Smiley :-/ MS Smiley :-\ Send spam to the FTC at Thanks, robots.
(it was 100cc though -- 2 50cc cylinders. would do 100mph) -- Ed Light Smiley :-/ MS Smiley :-\ Send spam to the FTC at Thanks, robots.
Can you supercharge a conventional 2-stroke? I know of 2-stroke supercharged diesel engines but on petrol?? And I've just briefly Googled to a few concepts but they seem relatively "unconventional". Bummers
Large two-stroke diesels have exhaust poppet valves where the exhaust valve timings can be controlled. With exhaust ports you would need an increased exhaust back pressure to assure sufficient scavenging and pressure in the cylinder at inlet valve closing. I doubt this project of supercharging a standard moped is feasible. You would in any case need a variable flow resistance exhaust system to test the engine with the supercharger. Whether it will work well on the full load range after being "calibrated" like this, I don't know. Note that for a petrol engine, any scavenging charge going through the cylinder and into the exhaust system will contain unburned fuel, increasing fuel consumption and emissions. (For a diesel this is only air, and only the pumping work will be lost.) Increasing the exhaust back pressure is therefore essential. Please post the results if you try it.
modern two stroke engine technology was developed to overcome the post war ban on supercharging. Pre war DKW was very sucessful with blown two strokes. But very different from today's state of the art
