1. HYBRID MOTOR
VECHICLES

2.  A Vehicle uses two or more two or more
distinct power sources to move the vehicle.
 The term most commonly refers to hybrid
electric vehicles (HEVs), which combine an
internal combustion engine and one or
more electric motors.

3.  Two wheeled and cycle type
 Parallel Hybrid Bicycle
 Series Hybrid Bicycle
 Heavy Vehicle
 Rail Transport
 Road Transport(Commercial Vehicles)
 Military Off-Road Vehicles
 Aircraft

4.  Hybrid electric-petroleum vehicle
 Parallel Hybrid
 Mild Parallel Hybrid
 Power Split or Series Parallel Hybrid
 Series Hybrid
 Continuously outboard recharged electric vehicle
(COREV)
 Hybrid fuel (dual mode)
 Fluid power hybrid
 Electric-human power hybrid vehicle
 Plug-in Hybrid Electric Vehicle
 Fuel cell, electric Hybrid

5.  Current HEVs reduce petroleum consumption under
certain circumstances, compared to otherwise similar
conventional vehicles, primarily by using three
mechanisms
 Reducing wasted energy during idle/low
output, generally by turning the ICE off
 Recapturing waste energy (i.e. regenerative braking)
 Reducing the size and power of the ICE, and hence
inefficiencies from under-utilization, by using the
added power from the electric motor to compensate
for the loss in peak power output from the smaller ICE.
