Mazda commenced advancement on one rotor engine displacing 360 cc (22 cu in), and was suitable for kei motor vehicle use inside the upcoming Mazda Chantez but was never put into output.
By far the most distinguished four-rotor engine from Mazda, the 26B, was employed only in various Mazda-built athletics prototype cars including the 767, 787B as well as RX-792P in substitute with the more mature 13J.

The cross-sectional place to the ingestion ports is surely an almost 30% more substantial as compared to the 13B-REW engine. The engine equipped with lighter areas to scale back rotational mass: rotors are lighter by fourteen%, flywheel - by twenty%. That gave a high throttle responds, much more electricity, and enables the engine to rev nearly 8200 rpm.
