A rotary engine is an
ideal powerplant for a sports car. Compared to a conventional engine of similar
displacement, the Mazda RX8's rotary engine is lighter since there is no need
for pistons, connecting rods or a camshaft.
The new 2004 2005 RX8's
lightweight, closed-section powerplant frame is made of steel and locks the
entire powertrain (engine, transmission and final drive assembly) into a
single, rigid unit. This mechanism improves responsiveness and shifting
operation while reducing driveline lash and windup.
2004 2005 Mazda RX8's
rotary engine is substantially smaller in size than a conventional engine,
which enables optimal positioning of the drivetrain. This results in increased
space that can be designated to driver and passenger comfort.
It produces less vibration – all of the new 2004 2005 parts in the rotary
engine spin continuously in one direction, rather than violently changing
directions, like the pistons in a conventional engine. RX8 Rotary engines are
also internally balanced, minimizing vibration levels. And
the new rotor, which is smoother than the back-and-forth action of a piston,
delivers power during three-quarters of each rotation of the output shaft. A
conventional engine delivers power during only one-quarter of each rotation of
the output shaft.
The 2004 2005 Mazda RX8
rotary engine has far fewer moving parts than a comparable four-stroke piston
engine. A new 2004 2005 2 rotor rotary engine has three main moving parts: the
two rotors and the output shaft. Even the simplest 4 cylinder piston engine has
at least 40 moving parts, including pistons, connecting rods, camshaft, valves,
valve springs, rockers, timing belt, timing gears and crankshaft
