JCPJCP Posted November 1, 2006 Share Posted November 1, 2006 The Diesel-Air design appears to be alive and well at Howells AeroEngines http://www.howells-aeroengines.co.uk/ They just added a little more info to the web page. John Quote Link to comment Share on other sites More sharing options...

JCPJCP Posted February 2, 2008 Author Share Posted February 2, 2008 Availability date once again slipped, from late 2007 to late 2008. Web page has a link to a write up of a local group's visit to the factory. A problem was revealed. JCP Quote Link to comment Share on other sites More sharing options...
Aiman Posted February 2, 2008 Share Posted February 2, 2008 I don't see any real problem, unless you consider the opposed piston design to be an issue... Quote Link to comment Share on other sites More sharing options...
JCPJCP Posted February 3, 2008 Author Share Posted February 3, 2008 Problems: 1) The blower was shearing off it's shaft on shutdown. 2) The "Gemini" diesel, which appears to be a direct decedent of this design, alludes to crankshaft failures on their web page. What I'm saying is that there appears to be issues with each of the long awaited diesel designs. Be it Zoche, DeltaHawk, Wilksch, or DAIR (now Howels and FTI Diesel Tech), each one has been delayed by some undisclosed design problem. Not that designs based upon Automotive Diesel blocks are any better, as they all seem to be chewing up gear boxes. regards JCP Quote Link to comment Share on other sites More sharing options...

emteeoh Posted February 4, 2008 Share Posted February 4, 2008 Wilksch must be ahead of the others. Bill Allen, made first flight in his Wilksch powered long eze on saturday. I dunno about that. DH has been flying a DH-powered Velocity for some time now (I think its almost 2 years now, but don't quote me on that). But one flying plane does not mean they have a reliable and manufacturable engine. Of course, I dunno who Bill Allen is. If that's a customer, nevermind me.

Bill Allen rebuilt a long eze that had been flying for over 20 years and removed the O-200 for the wilksch engine and has done a great job and it is a big step forward for the engine. check out his web site.http://www.longezediesel.com/ Quote Evolultion Eze RG -a two place side by side-200 Knots on 200 HP.

Aiman Posted February 5, 2008 Share Posted February 5, 2008 http://www.longezediesel.com/ Wow.. I would have never believed it if I hadn't seen the videos for myself. VERY cool, and runs on Jet-A. You can get that at most larger GA airports! Quote Link to comment Share on other sites More sharing options...
