Best Answer

An engine designed by Felix Wankel and idea bought/funded by Mazda to use in vehicles. Normally was to be used in aircrafts due to its lightweight and great power to weight ratios. These engines are very different from piston, creating the combustion process all in one chamber. Rotary engines are known to be lemons because if you are not a car enthusiast, then you don't know much about how to take care of a rotary engine car. I am not saying it is unreliable but it is unforgiving to abuse and mistreatment than other cars. If you take care of your car very well, then you can own a rotary, along with the right knowledge.

Engines that operate with rotors instead of pistons or cylinders are seldom used in modern automobiles because?

1. Problems with emissions control. Rotary engines use direct oil injection and this means oil is constantly burning with the fuel. 2. Economies of scale. Due to the complex nature of rotary engines very difficult to repair in relation to piston engines and very few people are trained to maintain and build these engines 3. Fuel consumption. Rotary engines are notoriously expensive to run on fuel. 4. Lack of low down torque/driveability. Rotary engines makes a tremendous amount of power at high RPM but insignificant torque in the lower rev ranges. 5. Ignorance. If more people disregard all of the above and eventually get to drive a rotary powered for for a while, they'd be converted. Unfortunately almost all rotary owners are petrolheads and adrenalin junkies!
