Rotary Engine or Wankel Engine:
A rotary engine or Wankel engine is a type of internal combustion engine. In this design, it is the crankshaft that remains stationary while the triangular rotor rotates. Unlike conventional engines, rotary engines have the arrangement of the cylinder moving around a fixed crankshaft.
The rotary engine uses the combustion of the fuel to spin a triangular rotor around the central driveshaft. This engine successfully does away from the piston type and provides the crankshaft. These engines are perfectly balanced and very refined. Felix Wankel invented one of the most popular types of rotary engines. It has been employed in the powerful and famous Mazda sports cars. It is the most talentedly designed internal combustion engine of modern times.
The rotary engine is not as efficient as the piston engines. It has undergone research and for the development throughout the century all over the world. The main factors that make the rotary engines successful are smooth running, fewer parts and low weight. The rotary engine delivers a very smooth power because of less reciprocating parts while it delivers large rotating motion.
It has a low weight advantage as well. It is a very conventional engine that has the heavy flywheel which stores the energy in pulses and also reduces the vibrations. The rotary engines gain substantial power-to-weight ratio for not needing to add the flywheel. This engine rotates the cylinder block and creates its own speedy moving cooling airflow while running.
Dr. Felix Wankel invented the rotary engine. So, it is popularly known as the Wankel engine. This design has an eccentric curved housing. However, it has a triangular-shaped rotor moving inside it.
Furthermore, the Wankel engine is an internal combustion engine that uses an eccentric rotary design. It converts the pressure into a rotating motion. Among all the engine design and classifications, the Wankel engine has maximum advantages. It offers benefits such as compactness, smoothness, and simplicity. This type of engine offers more revolutions per minute or high speed, which gives more performance. Wankel engine also has a high power-to-weight ratio.
