Why I Love Rotary Engines: A Tribute to the Oil-Eating Machines
Introduction
Sure, the rotary engine may be an oil-eating machine filled with Nazi-designed spinning tortilla chips that turn money into nightmares, but god, I love them. My first car was an RX-7, and while, somewhat tellingly, I haven’t owned another rotary since, I think about them often. In this article, I want to pay tribute to the unique charm and appeal of rotary engines, despite their flaws.
The Fascination with Rotary Engines
Rotary engines have always held a special place in the hearts of car enthusiasts. Their unconventional design and distinct sound make them stand out from traditional piston engines. The rotary engine, also known as the Wankel engine, was invented by Felix Wankel in the 1950s. It gained popularity in the automotive industry due to its compact size, high power-to-weight ratio, and smooth operation.
The RX-7 Experience
My love affair with rotary engines began when I got my hands on an RX-7. The sleek design, the exhilarating acceleration, and the unique engine note made it a truly unforgettable driving experience. The RX-7’s rotary engine was a work of art, delivering power in a smooth and seamless manner. It was like driving on a cloud of pure joy.
The Drawbacks of Rotary Engines
However, it would be remiss not to acknowledge the drawbacks of rotary engines. One of the most notorious issues is their voracious appetite for oil. Rotary engines require oil to lubricate the rotor seals and maintain proper compression. This constant oil consumption can be a headache for owners, as they need to keep a close eye on oil levels and frequently top up.
Another concern is the complexity of rotary engines. Their design involves intricate moving parts that require precise maintenance and tuning. Finding a mechanic with expertise in rotary engines can be a challenge, and repairs can be costly. Additionally, the apex seals, which are crucial for maintaining compression, tend to wear out faster than piston rings in traditional engines.
The Legacy of the Rotary Engine
Despite these challenges, the rotary engine has left an indelible mark on the automotive world. Mazda, in particular, embraced the rotary engine and became synonymous with it. The RX-7 and RX-8 models showcased Mazda’s commitment to innovation and performance. The rotary engine’s ability to rev high and deliver power in a smooth and linear manner made it a favorite among racing enthusiasts.
The Future of Rotary Engines
While Mazda discontinued the production of rotary-powered vehicles in 2012, there is still hope for rotary engine enthusiasts. Mazda has been working on a new generation of rotary engines, known as the SkyActiv-R, which aims to address the issues of fuel efficiency and emissions that plagued previous iterations. The SkyActiv-R engine is rumored to make its debut in an upcoming sports car, reigniting the passion for rotary engines.
Conclusion
In conclusion, despite their flaws, rotary engines hold a special place in the hearts of car enthusiasts. Their unique design, distinct sound, and exhilarating performance make them a true automotive gem. While they may not be the most practical or economical choice, their charm and character are unmatched. As we await the resurgence of rotary engines with Mazda’s SkyActiv-R, let us remember and appreciate the legacy of these oil-eating machines.
