Answers: How does the rotary engine in the Mazda MX-30 R-EV work and how can a rotary engine have variable intake timing?

• rotary engine design
• Mazda MX-30 R-EV powertrain
• variable intake timing in rotary engines
• apex seal design
• exhaust gas recirculation in rotary engines

What it concludes

• The Mazda MX-30 R-EV uses a single-rotor engine acting as a range extender rather than powering the wheels directly.
• The new rotary engine features direct fuel injection into the combustion chamber, aluminum side housings, and ceramic coating for improved wear resistance and efficiency.
• A Mazda patent proposes using an additional electric motor connected to the eccentric shaft or the generator to vary the rotor speed and achieve variable intake timing.
