Abstract
The fuel economy of the Mazda rotary engine was steadily improved through engine modifications and emission control system refinements.
Aiming at further improved fuel economy under the 1981 emission standards, thorough efforts were made to further improve gas sealing and ignition system and also to achieve optimum air fuel mixture. It was found that a new emission control System was desirable to maximize above-mentioned improvements.
As a result, a new catalyst system for rotary engine has been established, making a substantial improvement in fuel economy under practical driving conditions. Further fuel economy improvement can be expected in the future mostly because of catalyst system's flexibility for engine modifications.
