Lenoir engine

In France in 1862, Beau de Rochas outlined the principles of the four-stroke engine so common today. ITowever, he never transformed those principles into hardware. Among the improvements proposed by de Rochas was compression of the charge prior to combustion. In contrast, the charge in the Lenoir engine was essentially at atmospheric pressure when combustion was initiated. 

The efficiency of the 1860 Lenoir engine was no more than 5 percent. An efficiency of 14 percent was... 

The isochoric heating process of a Lenoir engine receives air at 15°C and 101 kPa. The air is heated to 2000° C, and the mass of air contained in the cylinder is 0.01kg. Determine the pressure at the end of the isochoric heating process, the temperature at the end of the isentropic expansion process, heat added, heat removed, work added, work... 

French inventor Jean-Joseph-Etienne Lenoir builds the first practical internal-combustion engine, fueled by illuminating gas. 

The Lenoir cycle was the first commercially successful internal combustion engine. 

Internal combustion engine (Etienne Lenoir) Lenoir s engine, along with his invention of the spark plug, sets the stage for the modem automobile.
