Which car models are equipped with rotary engines?
1 Answers
Car models equipped with rotary engines include the Mazda RX7 and Mazda RX8. Characteristics of rotary engines: Rotary engines eliminate the reciprocating motion effect of pistons in traditional engine cylinders, directly converting the combustion expansion force of fuel and mixed gases into driving torque. Therefore, in terms of size, rotary engines are smaller than traditional engines. Additionally, rotary engines feature a low center of gravity and lightweight design, which can enhance vehicle handling to some extent. Disadvantages of rotary engines: Rotary engines have relatively high fuel consumption, primarily because the shape of the combustion chamber is not conducive to complete combustion, and the flame propagation path is longer, leading to increased consumption of fuel and engine oil. Moreover, rotary engines can only use spark ignition and cannot employ compression ignition, meaning they cannot use diesel fuel. Additionally, they have high requirements for manufacturing processes and costs.
