in you mean invent it was around 1858 or 1860
He is famous for the Lenoir cycle and the internal combustion engine.
Etienne Lenoir in 1858
Jean Joseph Etienne Lenoir developed the internal combustion engine in 1859. He was a Belgian engineer. Etienne Lenoir developed the first single-cylinder two-stroke engine by mixing coal gas and air to ignite a 'jumping spark' ignition system.
Jean Josephe Etienne Lenoir invented the internal combustion engine in 1858. He was born in the Belgian Province of Luxembourg in 1822.
The whole reason was GASOLINE
In, 1680 Christian Huygens designed the first internal combustion engine. In 1859, Etienne Lenoir designed the first commercially successful engine.
Étienne Lenoir was born to a father named Jean Lenoir and a mother named Marie Lenoir. He was a Belgian engineer and inventor known for his contributions to the development of the internal combustion engine. His family background, however, is not widely documented in historical records.
The first device that could be called a prototype of the internal combustion engine was invented in the fifth century, in the form of Roman machines used in sawmills. In the seventeenth century, this idea was expanded upon with the addition of gunpowder as a power source. Internal combustion engine development accelerated in the late 19th century, and they were widespread by the 1900s.
he invented the gas engine:)
One of the earliest uses of the internal combustion engine was in the 1860s with the development of the Otto engine by Nikolaus Otto. This four-stroke engine, which ran on gasoline, significantly improved efficiency and paved the way for modern automobiles. Another notable example is the gas engine created by Jean Joseph Etienne Lenoir in 1859, which was one of the first practical applications of an internal combustion engine for powering vehicles.
The internal combustion engine they say that Nikolaus August Otto did but actually he didn't find out about the gas engine until he started traveling as a salesman selling sugar and silverware in Germany.As the above answer says Etienne Lenoir actually invented the first internal combustion engine in 1859. He also invented a gas engine and what was named a toilet in 1860, and a naptha fueled four cycle motorboat in 1888. Apart from these he was awarded the Legion d'honneur in 1881 for developments in telegraphy during the France-Prussian war. My sources for the answer are from family history.
in 1860
