The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy. A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of ...
The Otto cycle is a description of what happens to a gas as it is subjected to changes of pressure, temperature, volume, addition of heat, and removal of heat. The gas that is subjected to those changes is called the system. The system, in this case, is defined to be the fluid (gas) within the cylinder.
The first implementation of the Atkinson cycle was in 1882; unlike later versions, it was arranged as an opposed-piston engine, the Atkinson differential engine. [6] [7] In this, a single crankshaft was connected to two opposed pistons through a toggle-jointed linkage that had a nonlinearity; for half a revolution, one piston remained almost stationary while the other approached it and ...
All Wisconsin's products were 4-cycle and they had power outputs from 2.4 to 65.9 horsepower (2 to 49 kW). There were single, inline two, V-two, and V-four cylinder models. The engines were designed for outdoor field service in industries including agriculture, construction, marine, oil-field equipment and railway maintenance. [6]
The Tour Engine [5] is an opposed-cylinder split-cycle internal combustion engine that uses a novel Spool Shuttle Crossover Valve (SSCV) to transfer fuel/air charge from the cold to hot cylinder. The first prototype was completed on June, 2008. Tour Engine was funded by grants from the Israel Ministry of National Infrastructures, Energy and ...
Thermodynamics. In engineering, the Miller cycle is a thermodynamic cycle used in a type of internal combustion engine. The Miller cycle was patented by Ralph Miller, an American engineer, U.S. patent 2,817,322 dated Dec 24, 1957. The engine may be two- or four-stroke and may be run on diesel fuel, gases, or dual fuel. [ 1]
Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
This is a video montage of the Otto engines running at the Western Minnesota Steam Threshers Reunion ( WMSTR ), in Rollag, Minnesota. (2min 16sec, 320x240, 340 kbit/s video) The Otto engine is a large stationary single-cylinder internal combustion four-stroke engine, designed by the German Nicolaus Otto. It was a low-RPM machine, and only fired ...
