Mazda's New Rotary Engine

Many different designs for rotary mechanisms have been attempted over the last 400 years, but what makes the NSU-Wankel engine, which Mazda adopted, stand out is its "rice ball-shaped" (triangular) rotor housing. Because of this design, three separate chambers are created between the rotor and the inner wall of the rotor housing. These chambers smoothly expand and contract in a constant cycle as the rotor spins.


The Rotary Engine of Mazda continues to evolve farther into the future. The new generation Rotary Engine "RENESIS" makes it superbly environmentally friendly with zero CO2 and almost zero NOx emissions. Mazda began commercial leasing in 2006, and currently many organizations and government bodies are enjoying the RX-8 Hydrogen RE.
