Components of the Automobile.
The automobile is
made up of three basic parts: the power plant,
or the engine, the chassis and the body.
The engine is the source of power that makes the wheels rotate and the car move. It includes fuel, cooling, lubricating and electric systems. Most automobile engines have six or eight cylinders.
The chassis includes a power train (power transmission), a running gear, steering and braking systems as well.
Слайд 8
The power train carries the power from the
engine to the car wheels.
The power transmission, in turn,
contains the clutch, gearbox, propeller or cardan shaft, final drive, differential, real axle shafts. The running gear consists of a frame with axles, wheels and springs.
The body has a hood, fenders and accessories: the heater, stereo tape recorder, windshield wipers, conditioner, speedometer and so on.
