Advantages and disadvantages of the rotary engine

Advantages and disadvantages of the rotary engine
Rotary engines are alternatives to piston engines. They have different mechanics than the latter, but, like piston engines, they are internal combustion. The cameras change sizes as the rotor spins around. Rotary engines are to be considered as advances in engine technology in relation to those that are older. However, there are advantages and disadvantages in rotary engines.

Rotary engines have some distinct characteristics that differentiate them from other engines. They have no pistons. Piston engines have a compression and ignition system, however, a rotary engine does not work like this and performs these tasks in a single rotation. It has a triangular rotor rotation system that revolves around and completes its tasks in one movement.


Simplicity is an advantage of the rotary engine. It has much less parts than piston engines and still has more power in comparative terms. For example, the 13B of RX8 is a 1.3-liter rotary engine and yet produces enough power to compete with the Corvette's 6.0-liter piston engine. In this example, the 1.3-liter rotary engine produces 232 horsepower, compared to 178 horsepower of the 6.0-liter Corvette piston engine.

Limited catastrophic failures

Piston engines are more likely to experience catastrophic failures than a rotary engine. A piston can fail and cause many problems for a piston engine. On the other hand, rotary engines can also lose power, but at a much lower rate than the piston engine. However, even when rotary engines lose power, such engines continue to produce limited energy. Rotary engines will continue to run at a much lower rate up to a certain point.


Rotary engines have a big disadvantage when it comes to gas mileage, since they use more gasoline than piston engines. They also burn more oil comparatively than piston engines. This problem is not by default, but by design. Part of the reason is that the rotary engine is designed to mix a small portion of oil with gas for lubrication purposes. A typical rotary engine achieves an average mileage of about 25 miles (40.23 km) per gallon. It is also important to note that rotary engines could not run on diesel fuel due to their design.

The seal problem

Rotary engines tend to have more problems with the seal than piston engines. This problem occurs more frequently, especially in colder regions. It is not very clear why this is the case. There is also a problem with the cost of some spare parts. Repairs can be more expensive on a comparative basis. In addition, there are fewer distributors that are certified to fix rotary engines, and regular distributors of piston engines do not drive such engines.
