Talk:EMD 567

untitled
There is a great EMD 567 article by noted EMD Historian Preston Cook titled "The EMD 567 Engine in the 21st Century" at the  Railway Preservation News Website at http://www.rypn.org/ Look in the Archives section for the article. --SSW9389 (talk) 18:20, 17 April 2008 (UTC)

The EMD MRS-1s were rated at 1600 horsepower, see page EMD-131 of DSG2.--SSW9389 (talk) 18:20, 17 April 2008 (UTC)

Union Pacific sent six GP9s and three GP9Bs back to EMD in March-May 1959 for uprating with turbochargers. These may have been the first 567D2 engines or a turbocharged 567C. The Don Strack Article on Utah Rails is not clear if these units were reengined. --SSW9389 (talk) 18:20, 17 April 2008 (UTC)

The first 16V-567D3 engine was used in January 1958 as a peaker unit at the LaGrange plant of EMD. The first demonstrator SD24 #5579 was built by EMD in July 1958. See The GP20 and SD24 EMD's Turbocharged Duo by Diesel Era--SSW9389 (talk) 18:20, 17 April 2008 (UTC)

The first 16V-567D3As were used in the EMD GP35 demonstrator #5652 of July 1963. Diesel data from A J Kristopans website--SSW9389 (talk) 18:20, 17 April 2008 (UTC)

There were five GMD built SW900s built past the end production date given in DSG2. The last SW900 was built in April 1969. I do not know if 567C or 567E blocks were used in these late SW900s. Diesel production data from A J Kristopans website. --SSW9389 (talk) 18:24, 17 April 2008 (UTC)

Export production data suggests that the EMD 567 engine was produced up until late 1968 or early 1969. This 567 engine article does not reflect export model production or horsepower ratings. Add that to the list of things to do. --SSW9389 16:22, 4 October 2008 (UTC) —Preceding unsigned comment added by SSW9389 (talk • contribs)

567E
In the table - should it read "567 with 645 power assemblies" ? Sf5xeplus (talk) 17:26, 23 August 2010 (UTC)
 * No, it is correct as is, a 645 "E" block with 567 power assemblies. With 645 power assemblies, it would be a 645. Wuh  Wuz  Dat  18:54, 23 August 2010 (UTC)
 * Sorry - I get it now - I'm not very clued up on which bits are which in combustion engines.Sf5xeplus (talk) 20:11, 23 August 2010 (UTC)


 * Someone might want to check the HP figure for the 16V version Victorian Railways X class (diesel) quotes 1840HP not 2000 ? Sf5xeplus (talk) 20:36, 23 August 2010 (UTC)

A search of the 1991 EMD Product Data has revealed export units built with the 567E engine as late as February 1969. This is an ongoing search that will reveal quite a bit of detail on these late 567 engines. --SSW9389 (talk) 14:57, 11 February 2018 (UTC)

Notes changed to small letters, move one, add one. Versions main ref NOT CORRECT. Models table played with, 2 "none built" deleted.Sammy D III (talk) 00:14, 24 July 2013 (UTC)

Natural vs forced aspiration. All EMC/EMD 2-strokes require forced induction to run. Air is blown thru the intake ports on the bottom of the bore, forcing exhaust out the exhaust valves in the head. Natural aspiration sucks the air in, as in non-turbo 4-stroke auto engines and some small 2-strokes (motorcycles and yard equipment such as weed-wackers and snow-blowers). I used "induction" simply because I have never heard "forced aspiration" used, unlike "natural aspiration", which is common.Sammy D III (talk) 00:32, 24 July 2013 (UTC)

Roots supercharger and turbocharger are both forced induction
Please read the fourth and fifth sentence of Two-stroke diesel engine. There is more information at:Naturally aspirated, Forced induction, Roots-type supercharger, Turbocharger, and HowStuffWorks Sammy D III (talk) 04:34, 8 March 2014 (UTC)
