RECENT TECHNOLOGY DEVELOPMENT OF HIGH-POWERED ROTARY ENGINE AT MAZDA
In response to today's market demands, technological development for high-powered rotary engines has been under way for application to passenger models and racing engines. This paper describes first the development work devoted to achieve higher output, including a turbocharger system, tuned induction and exhaust systems, combustion chamber shape, ignition system. New technologies used for components so as to cope with higher power output, thus securing engine reliability and durability are discussed. Those technologies include a new surface treatment for improved lubrication of the trochoid surface, reduction in rotor gear stress, and optimization of the spark plug and igniter system. Those development efforts resulted in production of: TURBO CHARGED 573 cc x 2 rotors, 165 ps/6500 rpm engine for passenger car and 573 cc x 2 rotors, more than 260 ps/9000 rpm engine and 654 cc x 2 rotors, more than 300 ps/9000 rpm engine for racing.
