Drive-train/Transmission of vehicle

What is Drive train or Transmission line of a vehicle?
Ans.  The drive line of a car includes the flywheel, clutch, drive shaft, gear box, differential  and axle shaft along with necessary universal joints. Drive line transmits power from engine to wheel through all these parts.

      When drive line transmits power from engine to Front Wheel it is called Front Wheel Drive, when power delivers to Rear wheel it is called Rear Wheel drive and in some vehicle power is delivers to all the four wheel it is called All Wheel drive or Four Wheel Drive.
      
What is Drive train efficiency?
Ans. The power develop by the engine is delivers to wheel through drive line. But practically it is observed that the power available at wheel is less than that of power develop by the engine. There is loss of power in the drive line. The loss is mainly due to the inertia of all rotating part like flywheel, clutch, drive shaft, gears etc. Some amount of torque needed to rotate all these part and the loss is more  when no. of rotating parts and mass of the rotating part is more.
