Felix Wankel Invented the Wankel Engine
The Wankel Engine is a type of internal combustion engine that revolutionized the automotive industry when it was first invented by Felix Wankel in the 1960s. It uses a unique rotary design instead of the conventional piston engine technology. This unconventional design provided many advantages over traditional engines and has been used in various applications to this day.
A New Type of Internal Combustion Engine
The Wankel Engine’s innovative design is unlike traditional engines with a reciprocating piston. Instead, the Wankel engine uses a rotor, which rotates in a specific housing, separating the four strokes in four separate, adjacent chambers. The rotor turns in a stationary, metal housing, which contains a shape similar to an epitrochoid. The rotor does not rub against it, but slides along it with a close seal, allowing for up to three different variables from this design; the combustible charge is completed in each of the four chambers before returning to the starting point, making the process more efficient than traditional engines.
The Advantages of the Wankel Engine
The Wankel engine’s rotary design provides several benefits, which include higher power output, lower weight, and lower emissions. Higher power output is achieved by the engine’s ability to rotate three times for every combustion cycle. Lower weight is provided by the engine’s less complex design, requiring fewer parts than traditional engines do. This simple design also translates to lower emissions, resulting in a reduction of pollution and environmental impact.
The Wankel engine can handle high RPMs, resulting in a smooth and quiet operation, making it a popular choice for many applications, such as sports cars, motorcycles, and even lawn mowers. Additionally, the engine’s excellent power-to-weight ratio makes it particularly suited for use in aircraft.
Applications of the Wankel Engine
Since its invention in the 1960s, the Wankel engine’s unique design has been used in a variety of applications. This rotary engine is especially ideal for aviation and aerospace industries because of its compact size, high power-to-weight ratio, smooth operation, and low noise level. It has also been used in automobiles, motorcycles, personal watercraft, and even power generators.
In the automotive industry, Mazda was the first manufacturer to invest in the Wankel engine and launched a production line of rotary-engine vehicles in the early 1970s. These cars, including the Cosmo, RX-3, RX-7, and later RX-8, were popular among sports car enthusiasts, delivering a unique driving experience with smooth operation, high RPM handling, and quick acceleration.
Today, the Wankel engine continues to find its place in various applications, with improvements to its design, such as the addition of turbocharging, improving its efficiency and power output, making it one of the best alternatives to traditional engines.

The Rotary Engine Design
How the Wankel Engine Works
The Wankel Engine is a type of rotary engine that was invented by German engineer Felix Wankel in the 1950s. This innovative engine design uses a unique spinning motion, instead of the conventional piston movement found in combustion engines. The Wankel Engine’s distinctive structure revolves around a triangular rotor that rotates within an oval-shaped chamber, resulting in the production of power.
The Wankel Engine’s working principle is quite simple, a triangular rotor rotates within a stator, forming three separate combustion chambers. The combustion chamber’s rotation between the points of the triangle initiates a four-stroke cycle, which occurs simultaneously in each of the three chambers. These cycles encompass intake, compression, ignition, and exhaust.
The Wankel Engine utilizes a unique rotor and stator orientation, improving engine efficiency, and performance. Although the Wankel Engine structure requires fewer moving components than the traditional combustion engine design, it does require more precise components, such as the seal between the rotor and the chamber walls.
The Advantages and Disadvantages of the Rotary Design
The Wankel Engine design offers several advantages over the traditional piston engine. One of the most significant advantages is that the rotary engine design has fewer moving parts, translating to reduced friction, and smoother operation. The engine’s unique structure creates an unparalleled power-to-weight ratio, resulting in higher power output.
While the rotary design has many advantages, it also comes with some drawbacks, such as higher fuel consumption and lower efficiency at lower speeds. The engine’s moving components require precise tolerances, leading to increased friction at higher loads and higher emissions.
However, manufacturers have continued to refine the Wankel Engine design, with advancements such as electronic fuel injection and improved rotor sealing. These advancements have led to significant fuel efficiency gains and reduced emissions, making rotary engines a popular engine choice for small aircraft and sports cars.
The Future of the Rotary Engine
The Wankel Engine’s future remains bright as researchers and engineers continue to refine the design to improve efficiency and reduce emissions. The rotary engine’s exceptional power-to-weight ratio makes it an ideal engine choice for niche industrial applications that require high power output without adding additional weight.
While it is unlikely that the rotary engine will replace traditional engines in everyday automobiles, several manufacturers have been developing hybrid rotary designs to improve fuel efficiency. In a hybrid design, the electric motor provides power during lower speed and cruising conditions, while the rotary engine handles high-powered demands.
In conclusion, the Wankel Engine is a revolutionary engine design that changed the way we think about combustion engine technology. Its unique structure and superior power-to-weight ratio make it an engine choice for industrial applications requiring high power output, including aviation and automotive racing. As technology continues to advance, we can expect to see hybrid designs that incorporate the best of both worlds – the fuel efficiency of an electric motor with the exceptional power of a rotary engine.
