The rotary engine is an innovative design of a combustion engine, primarily for cars and mostly by Mazda.
| “ | Using a central spinning part in the combustion cycle meant the rotary engine was lighter and more powerful than what piston engines could typically achieve at the time, and this made it ideal for sports cars. ... The drawbacks - like a lack of power lower in the rev range, and fuel economy that would make even a Land Rover Discovery look smug - didn’t matter so much, and so the engine made its debut in the Cosmo Sport in 1967. Producing 110bhp at 7,000rpm and completing a quarter-mile sprint in 16.4sec, the Cosmo topped out at 115mph, thus proving that rotary power was viable, competitive and desirable.[1] | ” |
The Mazda RX-8 was manufactured for a half-century until it was discontinued in 2012.[1]
The Wankel engine is a type of rotary engine.
Hybrid models
A new Japanese patent discloses using a rotary engine stars in hybrid cars.
In another development, "LiquidPiston ... invent[ed] a new optimized thermodynamic cycle and a rotary engine platform. A thermodynamic cycle determines how much of the energy contained in the fuel can be converted into useful work output, with the balance being wasted as heat."[2]
History
There are 17,786 patents mentioning "rotary engine," dating back to 1840.
Mazda began making cars with the rotary engine around 1960, and American manufacturers considered using rotary engines around that time too. Credit for the invention is often given to the German Felix Wankel, who supposedly obtain a patent earlier on his odd design in 1929 (presumably in Germany), but he did not build a prototype until 1957.[3] Wankel had no engineering education.
Leftist opposition to the rotary engine
Leftists generally oppose all developments in energy, unless it results in government rationing as green energy does. Accordingly, Leftists opposed the rotary engine. The DailyKos admits that "[t]he engine was lightweight, compact, smooth, and had few moving parts,"[4] but then trashed it while comparing it to nuclear power.
