What is a ROTARY(wankel) engine

The image shows a cutaway model of a Wankel rotary engine, which is a unique type of internal combustion engine that operates quite differently from traditional piston engines found in most cars.

Instead of using reciprocating pistons, the Wankel engine employs a triangular rotor that rotates eccentrically inside a roughly oval-shaped housing. This rotation creates chambers that expand and contract, allowing for the intake, compression, combustion, and exhaust of the air-fuel mixture, much like in a piston engine.

Wankel engines offer several advantages, including a compact size, high power density, and fewer moving parts, leading to smoother operation and lower vibration levels. However, they also have some drawbacks, such as higher fuel consumption and emissions compared to modern piston engines.

Despite their unique design, Wankel engines have struggled to gain widespread adoption in the automotive industry due to challenges in meeting increasingly stringent emissions regulations and fuel efficiency standards. Nevertheless, they have found niche applications in sports cars, motorcycles, and other specialized vehicles where their compact size and high power output are valued.

The image appears to be from an exhibit or display, showcasing the inner workings of a Wankel rotary engine, likely to educate and generate interest in this innovative engine design.
