DETROIT – With a cat-like predatory stance, forward-thinking freestyle door system and enough room for four, not two, adults to enjoy all its benefits, the Mazda RX-8 has set itself apart from the pack. But if the recently introduced RX-8 production sports car truly is unique thanks, in large part, to its rotary engine, the RX-8 Hydrogen Rotary Engine (RE) concept, showcased this year at the North American International Auto Show (NAIAS), takes "unique" to all new levels.
Featuring a fuel system that consists of a high-pressure hydrogen tank, the vehicle balances the needs of the driving enthusiast and the environmentalist with a blend of alternative power and the exhilarating driving experience for which Mazda is known.
As the auto industry turns its attention to hydrogen fuel as a gasoline alternative, the RX-8 Hydrogen RE offers a hydrogen-powered version of RENESIS—Mazda’s next generation rotary engine that was introduced last year in the all-new RX-8. By virtue of its smooth performance, compact size and impressive driving characteristics, RENESIS was named International Engine of the Year in June 2003.
The RENESIS Hydrogen RE allows the RX-8 concept to run on either hydrogen fuel or gasoline and capitalizes on all the advantages of the rotary to assure RX-8’s ease-of-operation and reliability.
The RENESIS Hydrogen RE incorporates an electronically controlled hydrogen injector system, with the hydrogen injected in a gaseous state. The system draws air from the side port during the intake cycle and uses dual hydrogen injectors in each of the engine’s twin rotor housings to directly inject hydrogen into the intake chambers.
Because it offers separate chambers for intake and combustion, the rotary engine is ideal for burning hydrogen without the backfiring that can occur in a traditional piston engine. The separate induction chamber also provides a safer temperature for fitting the dual hydrogen injectors with their rubber seals, which are susceptible to the high temperatures encountered in a conventional reciprocating piston engine.
