Alphonse Beau de Rochas, a French engineer (1815-1893), ... created the ideal thermodynamic cycle of the 4-stroke engine (1862). Its cycle was implemented by Nicolaus Otto. Hence, the French use "cycle de Beau Rochas" but "Otto cycle" is more commonly used, especially in North America. 4, record 1, English, - four%2Dstroke%20cycle

Alphonse Beau de Rochas, [était un] ingénieur français(1815-1908). Il établit le cycle thermodynamique idéal des moteurs à explosion à quatre temps(1862) à allumage commandé. [...] Nicolaus Otto était un ingénieur allemand(1832-1891) qui industrialisa le premier moteur 4 temps suivant le principe de Beau de Rochas. Ce cycle théorique est la base du moteur 4 temps à allumage commandé dans lequel la combustion se produit à volume constant. 2, record 1, French, - cycle%20%C3%A0%20quatre%20temps

Puisque ce cycle fut établi par le Français Alphonse Beau de Rochas, il porte en France, le nom de son inventeur. Toutefois, puisque l’Allemand Nikolaus Otto industrialisa le premier moteur fonctionnant selon ce principe, ce cycle s’appelle ailleurs et surtout en Amérique du Nord, «cycle d’Otto». 5, record 1, French, - cycle%20%C3%A0%20quatre%20temps

Locomotives à gazoline. En traction souterraine, les locomotives à gazoline sont d’usage restreint, à cause de leur dégagement de gaz et de fumée. Le moteur généralement adopté est à 4 cylindres et à 4 temps(...) Les combustibles utilisés, outre la gazoline et l'éther liquide de pétrole, sont parfois à base de naphte, de benzine ou d’alcool.(...) La commande générale est à friction, par contact entre un disque d’acier et la roue à fibre. Le système de refroidissement comporte un radiateur à sections tubulaires, un ventilateur et une pompe. Le changement de vitesse-3 vitesses de 4 à 12 milles à l'heure-s’effectue par un volant vertical commandant la roue à fibre dans un mouvement transversal vers le disque à friction. Un dispositif placé sur le volant de commande permet de serrer la roue libre contre le disque de friction de manière à maintenir une vitesse déterminée, soit en avançant, soit en reculant; cette vitesse peut atteindre 12 milles à l'heure. 1, record 2, French, - locomotive%20%C3%A0%20gazoline
