It uses a triangular rotor rotational motion and to control the discharge of the compressed gas, the combustion gas can be directly converted to the expansion force of the driving force. Triangular rotary piston engine is a rotary engine.
1 Engine rotor principle
in the rotor pressure in the engine combustion chamber is kept in a sealed housing and a rotor consisting of a triangle.
Similar tracks the path of travel of the rotor respiration meter generated.
vertex rotor housing, thereby forming three separate gas chamber.
rotor constantly moving around the combustion chamber, the volume of three kinds of gases are alternately expanded and contracted.
It is this expansion and contraction of the air and fuel into the engine, and this gas mixture is compressed, and generate useful power as the gas expands, and finally discharging the exhaust gas.
2. The rotary engine of disadvantages
The rotary engine has several advantages, the most important thing is to reduce the volume and reduce the weight.
rotor engines that require few components.
However, disadvantages of a rotary engine is obvious: larger than 1 fuel.
2 – can not use compression ignition, diesel is not.
3. The position of the power output shaft is relatively high, the vehicle is arranged so arranged inconvenience.
3. High manufacturing rotary engine technology, the cost of more expensive, difficult to promote.
3 rotary engine history
this engine by the German Fei Jiashi # 8226;. Wankel invention, in summing up the results of previous research on some key technologies to solve problems, successfully developed the first rotary engine, and some so called Wankel rotary engine (WankelEngine).
available Wankel engine, so many powerful car manufacturers have the scent of a new era of technology.
However, the disadvantage of the Wankel engine is exposed in the startup test, but gave up the idea of a lot of challenges to the Wankel engine.
has always been a soft spot for the new technology Mazda bought the company has invested heavily in this technology from the company Wankel, Mazda purchased after the copyright to RE-Rotaryengine translation engine rotor Wankel engine as a new name .
In 1964, Germany and France in Geneva COMOBIL joint venture company, the first rotary engine installed in the car to become an official product.
In 1967, the Japanese are also mounted on the rotor Mazda car engine starts mass production.
the 1970s oil crisis, countries busy with all aspects of the difficulties and to attend to the development of the rotary engine, Mazda remains convinced that only the potential of the rotary engine, rotary engine research and production alone, and paid a fairly high price .
them to gradually overcome the shortcomings of the rotary engine, the successful transition from pilot production to commercial production, and break into the US market RX-7 sports car rotary engine is installed, impressive.
However, RX-7 in 1995 out of the US market.
