Longer lifespan

Slow speed of rotor seals Robust hydraulic solutions

Less noise pollution

No heavy part with reciprocating motion Less vibration : rotation in a cylinder generates no unbalance

Less gas pollution

Good control of combustion parameters (number and type of spark plugs, tumble, velocity of gas on intake) Little NOx (gas remains only briefly at high temperature owing to operating kinematics) Natural postcombustion effected by secondary air let into the passive variable-volume spaces. This air helps to cool the rotor by ventilation, and is evacuated via the exhaust.

High compression rate

Unlike the Wankel engine, the MRCC does not involve a difficult compromise between design parameters, choice of volumetric ratio and engine dimensions.

Better combustion

The combustion problems caused by the elongated shape of the Wankel engine's chamber and the movement of the flame front are non-existent in the MRCC

Better seal

The MRCC does not have the Wankel's airtightness problems because unlike the Wankel, the cylindrical shape of the stator allows the rotor seals to function at a constant angle to the stator wall.
