I. CONCLUSION
The production of dangerous greenhouse gas emissions
and consumption of world energy resources become a
serious problem. Especially CO2 emissions can influence
the climate stability of Planet Earth. The automobile
business contributes to this development a lot. But the
automobile technology has space to be improved. The
electric and hybrid electric vehicles can contribute to
diminishing of fuel consumption and green gases
production. The hybrid electric vehicles makes it possible
to operate the combustion engine in more suitable
regimes with better fuel combustion conditions. Some
hybrid systems even enable to operate the combustion
engine in best relation between power and revolutions.
Systems with power dividers allow the engine to operate
in revolutions that are quite independent from the car
velocity.
