Powertrain or power plant describes
the main part that generates power and delivers it to the wheels of a vehicle. The
components of a powertrain are the engine; transmission, drive
shafts, differentials, and the final drive. In hybrid powertrain the
battery, the electric motor and the control algorithm are also seen as
components of the powertrain. The
powertrain includes all of the components used to transform stored energy into
kinetic energy for propulsion purposes.
Powertrain system components such
as engine, transmission and brushless motor controller are responsible for efficient,
customer-specific control.
The engine supports the
control and adjustment of combustion processes, keeping track of information such
as engine speed, air quantity, temperature and optimising ignition,
fuel injection and other engine functions.
The control device
which gets together the sensors and actuators from automatic transmissions is a
fixed part of transmission control.
The brushless motor
controller operates the electrically powered auxiliaries, like the water pumps,
valves, air and throttle valves. The main function of the control device include
the rotor position, detection of BLDC, the retrieval of commutation information
and the rotating field as well as over current protection.
The fuel supply unit is an important component of the fuel system consisting
of a pump, filter and flange, with the other connections and a lever
indicator.
There is a constant demand to reduce emissions and improve fuel
efficiency which is making every powertrain and engine system component to
improve efficiency, integrate function, reduce weight and lower cost. Materials
play a critical role in helping to reduce emissions, boost fuel economy and
improve efficiency in powertrain technologies.
