2. What is a Hybrid Car?
 Hybrid is a combination of the two or
more source of power is use in to run
the car is known as hybrid car.

3. Components of Hybrid Car
 Gasoline Engine
 Fuel Tank
 Electric Motor
 Generator
 Batteries
 Transmission

4. Gasoline Engine
The hybrid car has an engine just like
most other cars. However the hybrid’s
engine is smaller than a normal
engine and uses advanced
technologies to reduce emissions and
increase efficiency.

5. Fuel Tank
 The fuel tank in a hybrid is the energy
storage device for the gasoline
engine. This is where the gas you put
in your tank is kept.

6. Electric Motor
 The electric motor is very
sophisticated in hybrids. Advanced
electronics allow for it to act as a
motor as well as a generator. It is able
to draw energy from the batteries to
accelerate the car, but it is also able to
slow the car down and return energy
to the batteries (called regenerative
braking, we will talk about this later).

7. Generator
 The generator is similar to the electric
motor, but it acts only to produce
electrical power.

8. Batteries
 The batteries in a hybrid car are the
energy storage device for the electric
motor. The electric motor from a
hybrid can put energy into the
batteries as well as draw energy from
them.

9. Transmission
 Transmission on a hybrid performs the
same as a transmission on our cars.
 How a transmission works is that it
takes power from the engine or motor
and sends to the driveshaft which
turns axle to move car

10. Technology ONLY Found in
HybridCars
Regenerative Braking
 It is an energy recovery mechanism which slows a
vehicle by converting its kinetic energy in to
another form.
 The energy from the wheels turns the motor,
functioning as a generator.
 This converts energy normally wasted during
coasting and braking into electricity.
 This electricity is then stored in a battery until it is
needed by the electric motor.

11. Technology ONLY Found in
Hybrid Cars
Automatic Start/Shutoff
 Automatically shuts off the engine
when the vehicle comes to a stop and
restarts it when the accelerator is
pressed.
 This prevents wasted energy from
idling.

12. Type of hybrid car
 Parallel hybrid car
 Series hybrid car

13. Parallel hybrid car
• Fuel tank supplies gasoline to the
engine and a set of batteries.
 Both of these supply power to the
electric motor.
• Both can turn the transmission at the
same time.

14. Series hybrid car
 Gasoline engine turns the generator.
 Generator either charges batteries or
powers an electric motor which
powers the transmission.
 The gasoline NEVER directly powers
the vehicle.

17. ADVANTAGES
 Less emission, particularly pollutants
such as carbon monoxide that are
leading to global warming.
 Sometimes emissions can be reduced
up to 90% by driving a hybrid car.
 Quieter
 Improved acceleration (most of the time)
 Less dependence on fossil fuels
 Some states provide incentives for
driving a hybrid
 Great driving experience

18. DISADVANTAGES
 More expensive
 Needs high fuel cost to be worthwhile
 Could cost more to repair
 Extra maintenance items
 Some hybrids need special tires

19. Conclusion
 By hybrid cars we can reduce the
using of the fossil fuels and friendly to
the environment and help in ‘green
house effect’ and to increase
efficiency.
