Hybrid Engine/Motor/Drivetrain Information
Introduction:
Hybrid engines vary greatly between manufacturers even thought the theory is
pretty much the same. Take an efficient petroleum based engine and couple it with
a high output electric motor. Additionally design an operating system that can choose the
most efficient power source to use depending on the vehicles situation. A gasoline
engine is more efficient at higher engine speeds, while the electric engine is more
usable at low rpm. To determine which engine is to be used an integrated computer
system is used to control all aspects of the power switch. In most cases the electric
motor will start the car in motion, and then when it gets to cruising speed the combustion
engine propels the vehicle. If the vehicle is designed with regenerative
brakes it means when the brake are applied a progressive variable generator
system is engaged.
In some hybrids this generator effect is created by changing the electric motor
current flow to produce electric power instead of consuming it. By controlling this
generating action a user can vary the resistance via the brake pedal creating more
or less resistance.
Ford Hybrid Motor
The hybrid electric motor can vary depending on design. The ford Hybrid engine
above is integrated into the transmission and is wide and stout. While the Honda
hybrid engine (below) is thin and has a larger circumference and is located between
the engine and transmission.
Honda Hybrid Motor
Hybrid transmission can vary also, the transmissions below works by centrifugal
force, the faster the wheels spin the higher the gear ratio. Hybrid cars also have
conventional 4 or 5 speed style of transmissions. The torque converter has
been replaced by an electrically controlled coupler that can be engaged and
disengaged. The electric motor has engine has three modes:
- Power Mode - This mode is used to propel the car
forward. The motor timing is controlled to produce the most power for a
particular application such as an aggressive take off versus a moderate
acceleration mode.
- Free-Wheel Mode - This motor mode is used while the
car is utilizing the internal combustion engine.
- Braking Mode - This mode is used while the brakes are
applied. The car is slowed by causing the electric motor to produce
electrical power.
