Internal combustion engine and Felice Matteucci tried to patent "Obtaining motive power by the explosion of gases", although the application did not progress to the granted stage. In 1860, Belgian Jean Joseph Etienne Lenoir produced a gas-fired internal combustion engine. In 1864, Nikolaus Otto patented the first atmospheric gas engine. In 1872, American George Brayton invented the first commercial liquid-fuelled internal combustion engine. In 1876, Nikolaus Otto, working with Gottlieb Daimler and Wilhelm Maybach, patented the compressed charge, four-cycle engine. In 1879, Karl Benz patented a reliable two-stroke gasoline engine. Later, in 1886, Karl Benz began the first commercial production of motor vehicles
Controlled combustion engine out by Orbital Australia, achieving a repeatable BSFC figure of 212g/kW-h (38.6% efficiency). Controlled combustion engine Controlled combustion engine (CCE) is a term used by Revetec, an engine design company, to identify a type of experimental internal combustion engine (ICE) designed by Brad Howell-Smith. It uses two counter-rotating cams instead of a crankshaft. Pairs of cylinders oppose each other in a boxer flat engine or X engine arrangement. The idea came to Howell-Smith, an automotive engineer residing in Australia, during REM sleep in 1995. He designed five different engine layouts with variations on each and established Revolution Engine Technologies Pty
