RENESIS - Super Responsive Rotary Engine for the New Millennium
The RX-EVOLV is equipped with the newly-developed, naturally-aspirated
"RENESIS" rotary engine, which revs eagerly to extremely high
engine speeds while producing racecar-like power and performance.
"RENESIS" stands for "The RE (Rotary Engine)'s GENESIS", or the rotary
engine for the new millennium.
The RENESIS engine is improved from the 13B rotary engine used in the
RX-7. Refinements include positioning the exhaust and intake ports
on the side housing, separate from the rotor housing. This reduces
overlap between the opening of the intake and exhaust ports, stabilizing
combustion. At the same time, it enables the intake port to be
enlarged, increasing engine rotational speeds and power output to levels
never-before achieved with a naturally aspirated production rotary
engine. Other refinements, including thinner, lightweight rotors,
thicker
eccentric shaft, and a 3-port, 3-stage variable intake system,
contribute to the engine’s maximum power output of 280 PS at 9,000 rpm,
maximum torque of 23.0 kg-m at 8,000 rpm and a 10,000 rpm redline.
A new, compact wet-sump oil lubrication system, making use of the
unique layout of the output shaft, and a thin oil pan contribute to the
engine’s lightweight compact design, which allows the engine to be
located lower and further to the rear than ever before.
The engine and transmission are unified with a final drive unit
connected by a carbon-fiber Power Plant Frame (P.P.F). This increases
rigidity
and provides direct, positive shift feel plus linear response to
movements of the accelerator pedal.
