Every single chamber quantity is 654 cc. The most important advancement is the 13B-MSP has two exhaust ports per rotor inside a aspect housing as opposed to one particular peripheral exhaust port for every chamber on the Mazda RX-7's engines. That reduces gas circulation resistance (Practically the double the exhaust port area than in the 13B-REW), removes intake/exhaust overlap, and raises thermal effectiveness, energy, and gas efficiency. Now the unburned gases are not carried in the next combustion cycle. The result is more steady and successful combustion. The 13B-MSP engine was available in typical and high-output variations. The conventional variations have two consumption ports for each chamber, and high-output - a few consumption ports per chamber (primary, secondary and auxiliary). The cross-sectional region for the consumption ports is undoubtedly an Just about thirty% much larger in comparison to the 13B-REW engine. The engine Outfitted with lighter sections to reduce rotational mass: rotors are lighter by 14%, flywheel - by twenty%. That gave a significant throttle responds, additional electric power, and enables the engine to rev up to 8200 rpm.
