The engine compressed the air/fuel mixture before combustion, unlike the other atmospheric engines of the time. The engine was a single-cylinder unit that displaced 6.1 dm 3, and was rated 3 PS (2,206 W) at 180/min, with a fuel consumption of 0.95 m 3 /PSh (1.29 m 3 /kWh).
Ray-traced image of a piston engine. There may be one or more pistons. Each piston is inside a cylinder, into which a gas is introduced, either already under pressure (e.g. steam engine), or heated inside the cylinder either by ignition of a fuel air mixture (internal combustion engine) or by contact with a hot heat exchanger in the cylinder (Stirling engine).
Consequently, steam engine pistons are nearly always comparatively thin discs: their diameter is several times their thickness. (One exception is the trunk engine piston, shaped more like those in a modern internal-combustion engine.) Another factor is that since almost all steam engines use crossheads to translate the force to the drive rod ...
The Pratt & Whitney R-4360 Wasp Major is an American 28-cylinder four-row radial piston aircraft engine designed and built during World War II.At 4,362.5 cu in (71.5 L), it is the largest-displacement aviation piston engine to be mass-produced in the United States, and at 4,300 hp (3,200 kW) the most powerful.
Rolls-Royce produced a range of piston engine types for aircraft use in the first half of the 20th century. Production of own-design engines ceased in 1955 with the last versions of the Griffon; licensed production of Teledyne Continental Motors general aviation engines was carried out by the company in the 1960s and 1970s.
Some two-stroke engines use pistons with a deflector head. Pistons are open at the bottom and hollow except for an integral reinforcement structure (the piston web). When an engine is working, the gas pressure in the combustion chamber exerts a force on the piston crown which is transferred through its web to a gudgeon pin.

The history of gasoline started around the invention of internal combustion engines suitable for use in transportation applications. The so-called Otto engines were developed in Germany during the last quarter of the 19th century. The fuel for these early engines was a relatively volatile hydrocarbon obtained from coal gas.
