Definitely not, supercharger are like centrifugal blower/compressor, imagine how would a single cylinder deliver an exhaust blow to it at the same time charging. Isn't that absurd? Dont you think.

Noudge79,

You have confused a turbocharger, driven by exhaust gas, with a supercharger, driven by a belt.

Neither is practical on a single cylinder engine.

Thanks lyn, i never thought really of the comparison between the two seriously. Ive taken I.C.E For about ten years ago, and i dönt like to answer quite accurate and detailed as to the point ill do a point to point computation for the OPs. I let them interact. Im fond of answering from stock knowldge to see if im still sharp. Thanks for reminding me, it is already stained =), yes my bad. But niether supercharger nor turbocharger, will fit to work a single cylinder engine. Imagine the supercharge blower doing at compression to power stroke-definitely a lost work

The start/stop air flow aspect of the intake valves being closed during the exhaust stroke would not let the air flow through the blower in a smooth manner.

One could probably get a few hp with a low boost blower, maybe 2#, which would also not use much energy. It could even be electric.

It would simply alleviate the hesitation in the air flow when the piston is on the intake downstroke by 'pushing' the air/fuel mixture into the cylinder instead of the piston having to pull it in.

I believe it has more to do with economics than ability. It has just been cheaper to make a simple engine that is 2x as large as the previous engine than to supercharge the smaller first one. Turbos, and superchargers seem to only be used when a larger sized engine would not be practical. And now with emissions, and fuel economy becoming more important, these options are being considered more often.
