Have you ever wondered why the only kind of engine used is the 4-stroke internal combustion, if there are any other alternatives to it? There is a little known engine called the Wankel rotary engine. This engine is very unlike the regular 4-stroke internal combustion engine used in most cars; it uses no pistons.
"Felix Wankel conceived the idea of a rotary engine in 1924" (Marr) which re received a patent for in 1936. Since then the rotary engine has bin developed by companies such as Mercedes-Benz, Chevrolet, Yamaha, Suzuki, Cessna, Artic Cat, Nissan and Mazda in the 1970s and 80s for motorcycles, cars, snowmobiles, airplanes, chainsaws, boats and even compressors and air conditioners. But only Mazda has continued to develop the engine and will include it in its upcoming sports car the RX-8.
Since it the rotary engine uses no pistons, the same volume of space (the cylinder) alternately does four different jobs: intake, compression, combustion, and exhaust. The pressure of combustion is contained in a "cylinder" formed by an apex of a triangular rotor (instead of pistons), and part of the housing. The rotor travels in a partially oval shape, keeping the apexes in contact with the housing, this forms three different volumes of gasses which alternately expand and contract, causing the suction required for to bring air and fuel in to the chamber.
The ignition and fuel delivery systems of a rotary engine are similar to a piston engine, but the other parts of a rotary engine are very different. The rotor [Figure A Rotor].

(piston) has three convex surfaces with pockets in it, which allow more displacement, and therefore more air/fuel mixture. The apex seals are what keeps the combustion chambers separate, and are like the piston rings on a piston engine.
The housing [Figure B Housing] for the rotor is roughly oval, and is designed so all the apexes off the rotor are in contact with the housing wall.

How does your engine work anyway? ... These engines are classified as reciprocating or rotary engines. In a reciprocating engine, the most common of the two, combustion takes place in a cylinder that has a piston that goes up and down, while a rotary engine has fewer parts and uses a disk based system (Internal Combustion Engine). ... This works because the rise in temperature an pressure during combustion is sufficient ot cause spontaneous ignition of the fuel. ... So how about Kerosene? ...
Going into these trying times of the thought of war and tactics, many people think about how in the world a 28,000-pound helicopter lifts off of the ground. People have said that lifting this size of an object would be impossible with just four rotary blades, an engine, and a drive-train system, but it happens every day. ... It is kind of like the engine of a car. ... The drive train also works much like the transmission of a car. ... To get a good picture of how the helicopter rises off of the ground, think of a ceiling fan. ...
James Watt also discovered how he could make Savery and Necomen's version of the steam engine more efficient. He worked on it for months to find out how to make a steam engine that cooled the used steam in the condenser separate from the main cylinder. ... Boulton was the owner of the Soho-Engineerring Works at Birmingham, where he also lived. ... Some of the improvements and inventions that are included in other patents are the rotary motion steam engine that was produced in 1781 which was for driving machinery. ...

In the late 20th Century, mass media could be classified[by whom?] into eight mass media industries: books, newspapers, magazines, recordings, radio, movies, television and the internet. With the explosion of digital communication technology in the late 20th and early 21st centuries, the question of what forms of media should be classified as "mass media" has become more prominent. For example, it is controversial whether to include cell phones, video games and computer games (such as MMORPGs) in the definition. In the 2000s, a classification called the "seven mass media" became popular. ...
