Mazda RX-8 2004 Service Highlights page 5

— Three injectors per rotor have been provided on the High power model (2 per rotor for Standard power).
Together with the electronically controlled (drive-by-wire) throttle valves and the 32-bit powertrain control
module (PCM), the injector arrangement has realized fine control of the air-fuel ratio and reduced response
time.
— New jet air fuel mixing system that promotes
atomization, vaporization, and mixing of fuel
has been adopted on the intake port unique to
the rotary engine, realizing improved
combustion and reduced fuel consumption.
Advanced front-midship layout
• Combination of state-of-the-art technologies such as a compact rotary engine, a thin engine oil pan, a forward-
located air intake system, a compact air-conditioning unit, has produced a small and light powerplant package.
• Adoption of an advanced front-midship layout,
saddle-shaped plastic fuel tank, and an
emergency puncture repair kit requiring no spare
tire has realized a 50-50 front/rear weight
distribution, minimal yaw-inertia moment, and
high roll-rigidity.
