The conventional variations have two consumption ports per chamber, and superior-output - three ingestion ports for every chamber (primary, secondary and auxiliary). The cross-sectional space with the ingestion ports is definitely an almost 30% much larger in comparison to the 13B-REW engine. The engine Outfitted with lighter parts to cut back rotational mass: rotors are lighter by fourteen%, flywheel - by twenty%. That gave a significant throttle responds, a lot more electricity, and lets the engine to rev up to 8200 rpm.
