According to the book Memories and Machines: The Pattern of My Life by Sir Harry Ricardo F.R.S., Page 192: "...the company was registered under the title of 'Engine Patents Ltd.', with Campbell Swinton as its first Chairman in July 1917." Not 1915 as stated in this article. Rupertlt (talk) 12:58, 25 January 2010 (UTC)

Hi there,

the Mercedes 260D had a totally different pre chamber design from the Ricardo Comet; this engine has nothing to do with the Ricardo development. Intrestingly Mercedes kept their Pre chamber design until the they swiched over to direct injection, whereas nearly all other companies used the Ricardo design. — Preceding unsigned comment added by (talk) 22:03, 6 February 2013 (UTC)

Sir Harry and steam[edit]

The contributors to the article certainly seem to be correct but I don't think that any of them actually met Sir Harry. (I did, and have made several corrections to this article. I worked at Ricardo for 42 years. DavidPaygate (talk) 11:01, 7 December 2016 (UTC))

In the 1950s and 60s Sir Harry used to tour UK schools giving science lectures and I still consider his lecture about hot air engines the best that I ever heard.

At heart Sir Harry was a steam fan and in his youth he built a steam trike. Before I ever thought to ask for details he was dead.

In the early 1950s Sir Harry, with the aid of Brigadier Cox, was contracted by the then National Research Development Council to design and build a small multi fuel steam engine complete with boiler, to be used in underdeveloped countries for driving machinery, pumping water, air conditioning etc. This may well have been the last commercially built steam engine.

The engines were designed and built with a couple going off to Rhodesia and more to India. The biggest market was hoped to be India so that the Indian imported oil bill would be reduced.

The whole idea flopped when it was finally realised that collecting waste fuel for a steam engine was the work of untouchables and no self respecting Indian small holder would demean himself with such work. Carrying oil fuel by bicycle over long distances wasn't the work of untouchables.

I suppose its the old adage of doing your homework first.

Some points in the Ricardo Consulting section are not mentioned in the main Ricardo plc article[edit]

Several points are mentioned in Harry Ricardo#Ricardo Consulting which are not included in Ricardo plc, which is the present name of that company. Probably they should be added to it, or if not, perhaps this section should be rewritten. Enginear (talk) 06:04, 31 October 2012 (UTC)

Is Ricardo Consulting the best name for that section?[edit]

The organisation has had several names in its time: initially Engine Patents Ltd, I am fairly sure it then became Ricardo Consulting Engineers, and was I believe still called that at the time of Ricardo's death. Later, it may have become Ricardo Consulting, though I'm not certain. Now it is Ricardo plc.

Since this is an article about Ricardo himself, it seems illogical to call the section by a name which the company was not known by in his lifetime, and is not known by now. If my memory is correct, then either Engine Patents Ltd or Ricardo Consulting Engineers would seem appropriate instead. However, I am not fully certain of my facts, so have not changed it.
