News Release Tag[edit]

This article should be expanded/rewritten to contain a reasonably detailed description of the technology in question, a meaningful comparison with other similar technologies, etc. Currently it reads more like PR puff. 24.79.211.192 (talk) 03:04, 21 March 2011 (UTC)[reply]

There's been stories videos of this circulating for a few years now (eg. [1]), all promising a working engine "by year's end". If it was a guy in a shed we'd be thinking "scammer".87.221.151.214 (talk) 20:25, 7 April 2011 (UTC)[reply]

I'd recommend that the Coates Engine technology (rotary valve system) be considered when considering alternative technologies. This one works and is real, but IIRC has challenges in meeting EPA NOx emissions - - I suspect that the cause is likely to be the same as here, namely higher combusion temperatures. -hh (talk) 14:58, 26 April 2011 (UTC)[reply]

to be fair, the ZDnet article linked above was written in 2009 and claimed that a car could be ready in two years, which is consistent with the "end of 2011" estimate. —Preceding unsigned comment added by 192.5.109.34 (talk) 20:47, 7 April 2011 (UTC)[reply]

source material for History section[edit]

Norbert Mueller, mentioned on this page, has previously published an overview and history (which goes back to the 1940's) of wave rotor engines. [2] Pie fed (talk) 16:28, 8 April 2011 (UTC)[reply]

Rewrite[edit]

I just rewrote and reformatted this article to make it sound less like a press release. Removed lots of "utilize" and "teams" talk which which didn't "synergize" well. Not much actual information on the engine itself, but the general principals are there, so it may be worthwhile to keep this article. — Preceding unsigned comment added by Nailedtooth (talk • contribs) 15:24, 9 April 2011 (UTC)[reply]

Vote(s) against deletion[edit]

I would like to see this article expanded, not deleted. The Michigan State University Arpa-E grant has generated a lot of PR about this type of engine. Wikipedia should have some explanation of what it is. Elizabeth Greene 9 April, 2011. —Preceding unsigned comment added by 68.52.244.134 (talk) 01:46, 10 April 2011 (UTC)[reply]

Wrong place. Your vote won't be counted here. Got to Wikipedia:Articles for deletion/Wave disk engine and vote there. Guy Macon (talk) 08:00, 10 April 2011 (UTC)[reply]

Dubious[edit]

The article includes the following statement: "The very first type of wave rotor was developed in the 1950s." However, according to page 720 this source:

Akbari, Pezhman; Nalim, Razi; Mueller, Norbert (2006). "A Review of Wave Rotor Technology and Its Applications" (PDF). Journal of Engineering for Gas Turbines and Power. pp. 717–735. Retrieved 2011-04-10. {{cite web}}: Unknown parameter |month= ignored (help)CS1 maint: multiple names: authors list (link)

a wave rotor was designed by the Brown Boveri Company in the 1940s, with tests performed 1941–43. Regards, RJH (talk) 20:08, 10 April 2011 (UTC)[reply]

No news is Good news?[edit]

Last hit for any real news on this thing is 2013. I'm assuming that this means that they hit some sort of problem that only government funding could attempt to solve since private investors would run away. How do we wrap this up? Here's a good summary on an absence of progress and reasons for it http://newenergyandfuel.com/http:/newenergyandfuel/com/2013/09/04/arpa-e-backing-the-msu-wave-disk-engine/ Greglocock (talk) 19:15, 20 November 2017 (UTC)[reply]

What is the temperature of the shockwave in the engine?[edit]

Can't find it anywhere. Thy, SvenAERTS (talk) 13:10, 24 June 2022 (UTC)[reply]
