Expanding article

I'd like to give more detail on SACM diesel engines and I've copied this from [[1]]:

3 gammes étaient proposées

MGO (MAREP Grosshans Ollier) 175 mm d'alésage. de 6 à 16 cylindres.
AGO (Alsacienne Grosshans Ollier) de 195 mm d'alésage de 12 à 16 cylindres.
AGO (Alsacienne Grosshans Ollier) de 240 mm d'alésage. de 12 à 20 cylindres.

My French is not good enough to translate it accurately. Can anyone help? I don't know what MAREP is but I think Grosshans and Ollier are the names of people. Biscuittin (talk) 17:50, 25 March 2014 (UTC)[reply]

3 types were proposed

MGO (MAREP Grosshans Ollier) 175 mm bore. 6 to 16 cylinders. [Grosshans Ollier refers to the inventors Georges Frederic Grosshans and Jacques Gaspard Ollier) - not sure about MAREP]
AGO (Alsacienne Grosshans Ollier) 195 mm bore cylinders 12-16. [Alsacienne refers to Société Alsacienne de Constructions Mécaniques
AGO (Alsatian Grosshans Ollier) 240 mm bore. 12 to 20 cylinders.

Thanks for the translation. I've looked at the Grosshans-Ollier patent (US patent 3,323,503 [2] of 6 June 1967) and it is for liquid-cooled pistons. I think AGO and MGO engines were actually built (not just proposed) but I have no references yet. Biscuittin (talk) 19:50, 26 March 2014 (UTC)[reply]

I've done some more research in French Wikipedia and found Moteur MGO [3]. This tells me that MAREP is Société de matériel et de recherche pétrolière. I've also found a locomotive with an MGO engine: BB 63400 [4]. Biscuittin (talk) 20:03, 26 March 2014 (UTC)[reply]

I've also found a loco with an AGO engine: CC 72000 [5]. This confirms that both AGO and MGO types were actually built. Biscuittin (talk) 20:07, 26 March 2014 (UTC)[reply]

I arrive a bit late for the discussion, but I confirm Grosshans and Ollier were people (Full disclosure: one of them being my grandfather) Frédéric Grosshans (talk) 12:35, 19 October 2015 (UTC)[reply]
