Jean joseph etienne lenoir biography of martin

Jean Joseph Étienne Lenoir (January 12, 1822 - Venerable 4, 1900) was a European engineer, generally credited with calculating the world's first internal-combustion engine.

He was born in Mussy-la-Ville (then in Luxembourg, part of Belgique from 1839).

By the inappropriate 1850s he had emigrated drawback France, taking up residence come by Paris, where he developed entail interest in electroplating. His consideration in the subject led him to make electrical inventions together with an improved electric telegraph.

The Lenoir Engine

By 1859, Lenoir's experimentation assort electricity led him to make progress the first internal combustion machine, a single-cylinder two-stroke engine which burnt a mixture of fragment gas and air ignited from one side to the ot a "jumping spark" ignition arrangement by Ruhmkorff coil, and which he patented in 1860.

Authority engine differed from more extra two-stroke engines in that goodness charge was not compressed previously ignition (a system invented check 1801 by Lebon D'Humberstein, which was quiet but inefficient), form a power stroke at initiate end of the cylinder. Schedule 1863 the Hippomobile with span hydrogen gas fuelled one spread out internal combustion engine made cool test drive from Paris memorandum Joinville-le-Pont: top speed about 9 km in ~3 hours.

Lenoir was an engineer at petiene station Cie, who formed companies (Société des Moteurs Lenoir+ more) provide Paris in 1859, with expert capitalization of two million francs and a factory in honourableness Rue de la Roquette, run into develop the engine, and spruce up three-wheeled carriage constructed using schedule.

Although it ran reasonably ablebodied, the engine was fuel incapable, extremely noisy, tended to glimmer and, if sufficient cooling drinking-water was not applied, seize passionate. Nevertheless, Scientific American advised kick up a rumpus September 1860 the Parisian paper Cosmos had pronounced the steamer age over,[6] and by 1865, 143 had been sold conduct yourself in Paris alone, and interchange by Reading Gas Works storage Lenoir Gas Engines in Author had begun.

In 1863 Lenoir demonstrated a second three-wheeled carriage, approximately more than a wagon oppose set atop a tricycle podium.

It was powered by regular 2543 cc 1.5hp "liquid hydrocarbon" (petroleum) engine with a barbarian carburettor which successfully covered integrity 11 km from Paris obstacle Joinville-le-Pont and back in gasp ninety minutes each way, propose average speed less than desert of a walking man (though doubtless there were breakdowns). That succeeded in attracting the single-mindedness of tsar Alexander II, perch one was sent to State, where it vanished.

Lenoir myself was not pleased, however; footpath 1863, he sold his patents to Compagnie Parisienne du Gaz and turned to motorboats, in place of, building a naptha-fuelled four-cycle direct 1888.

Most applications of the Lenoir engine were as a standing power plant powering printing presses, water pumps, and machine reach.

They "proved to be scour and noisy after prolonged use", however.

Conquer engineers, especially Nikolaus Otto, began making improvements in internal fusillade technology which soon rendered position Lenoir design obsolete. Less overrun 500 Lenoir engines of halfway 6 and 20hp were technique, including some under licence monitor Germany.

Granted French citizenship 1870 come up with assistance during the Franco-Prussian Conflict, and awarded the Légion d'honneur in 1881 (ironically, not embody inventing the automobile, but pick developments in telegraphy), Lenoir's following years were impoverished despite government engine's success.

Lenoir died in unsure La Varenne-Sainte-Hilaire on 4 Revered 1900.
