Powertrain or powerplant describes
the main part that generates power and delivers it to the wheels of a vehicle. The
components of a powertrain components 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 components such as engine, transmission and brush less 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 optimizing 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
brush less 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 powertrain 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 components 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 components technologies.
