I was getting confused with my terminology. A two stroke engine fires once per revolution, per cylinder. When monolith engines says "single stroke" I think they do mean to claim that one cylinder is getting two combustion cycles per revolution. It's a silly marketing claim, it's just a two stroke engine with two cylinders combined. Which makes me wonder - when they say they are attempting first trials with a "two stroke" design, does that mean they are actually running a four stroke cycle on two ends of one cylinder? It's as clear as mud, and only makes me more skeptical about their claims. -Adam On Fri, Aug 26, 2011 at 2:26 PM, John Gardner wrote: > Does Kiwi "single-stroke" =3D "two-cycle" in Gringlish? > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
