message: The various enthusiasts state that the lubricating oil is well separated from the combustion chamber. If so, how are the piston rings lubricated? Greglocock 12:53, 31 May 2007 (UTC)

thread_title: Oil

message: The drawing explicitly shows fuel injected into the transfer port. Is all air transferred into the combustion chamber of roughly equivalent fuel/air ratio? Or is the fuel injection timed so that the fuel is concentrated into the latter part of the scavenging cycle? Greglocock 12:53, 31 May 2007 (UTC)
thread_title: Charge separation

message: The model that is linked to from the article clearly shows a complex rotary plain bearing. The cross section linked to, from the article, clearly shows a similar plain bearing. Is there any eveidence at all that a slipper bearing is (a) used and (b) had a long life in this application and (c) was feasible in this application - the combination of rotary and longitudinal travel is quite complex.

replies: text:  Well, he's sent me a rather aggressive response saying that the account is true. The good news is that the link can go back in. The bad news is that the efficiency he observed is well below that claimed by the enthusiasts, and is in line with normal engineering expectations. I shall adjust the article accordingly.

text: Well, he is a real person who answers his emails, not an effectively anonymous contributor to wiki who seems to specialise in randomly inserting paragraphs in other people's comments. WHEN somebody tests one of the 15 Bourke engines and publishes the results then that may confirm the hype. So far all we've got is one test that shows the efficiency is nothing specal.
