Oh yes they are. The actual gear ratio
between the petrol engine and the
wheels varies.
Nope. Wrong again. The power splitter
apportions the power from the petrol
and electric motors to give "combined"
power and torque from the two, at the
wheels, eliminating a rise and lower
ratio gearbox. There you have it, but
will you comprehend? Not in million years.
Is there a motor AND a generator or is the motor used as a generator
when driven by the engine (can't see a point for motor and genny ..
perpetual motion and that ..)
A motor and a generator. The petrol motor will be turning the genny and that
turns the electric motor, or the battery can turn the electric motor
entirely or the motor can be fed from the battery and the genny. The power
splitter does all that. It is the planetary cluster and the management
system behind it that has made the hybrid. Many predict it will replace all
normal ICE/auto box within 5 years, then hydrogen or full EVs will take over
as battery technology take over from hybrids. The hybrid with a large
battery pack and a Stirling or Steam Cell, instead of an ICE would extend
the hybrid even further.
The power splitter "is not" a raise and lower ratio gearbox. A gearbox is a
"series" device, taking input from a shaft, raising or lowing the ratio, be
it manually, auto or sliding belts or toroidal, and then outputs a different
ratio via the output shaft to the wheels. Input - change ratio - output.
The power splitter just does not do that, it take power from two "parallel"
sources, petrol and electric motors, and outputs that power to the wheels.
Perpetual motion is when the output can be fed back to the input and run the
motor. It is called over-unity - which is when the output creates more
power than energy to run the motor. If only.
