Is the Mazda Axela Engine a Rotary Engine?
2 Answers
Mazda Axela engine is not a rotary engine. The following is an introduction to the engine: Comparison between rotary engine and traditional reciprocating engine: Both reciprocating engines and rotary engines rely on the expansion pressure generated by the combustion of the air-fuel mixture to obtain rotational force. The structural difference between the two engines lies in the way they utilize the expansion pressure. Introduction to rotary engine: For a rotary engine, the expansion pressure acts on the side of the rotor. This pushes one of the three sides of the triangular rotor toward the center of the eccentric shaft. This movement is carried out under the action of two component forces. One is the centripetal force pointing toward the center of the output shaft, and the other is the tangential force (Ft) that causes the output shaft to rotate.
As a car novice, when I first started learning to drive, I was also curious whether the Mazda Axela (Mazda3) used the legendary rotary engine, because it sounded advanced. But after checking the information, I found that it actually uses conventional piston engines, such as the Skyactiv-G gasoline engine, not the rotary type. Rotary engines were only used in Mazda's older RX-7 and RX-8 models, featuring unique designs but with many drawbacks, such as high fuel consumption and significant emission issues, making them unsuitable for family cars like the Axela. Nowadays, Mazda focuses on Skyactiv technology, which offers more fuel-efficient and reliable engines with smooth driving experiences. If you're concerned about power, don’t be misled—the Axela is a cost-effective choice.
