3. Read and translate the text. How it works: the motor car

The motor car is a form of mechanical transport and it is composed of many different, working units and parts. To provide the energy to make it go, it has an engine which in turn needs electric current, petrol and air. The engine needs cooling so that it does not become too hot and oil to lubricate the bearing surfaces.

Also, there is the transmission system of clutch, gearbox, propeller shaft and axle, which transmits the power from the engine to the wheels to move the car along the road. Steering mechanism is needed to guide the car in the right direction, brakes to slow it down and stop it, and suspension to smooth out most of the bumps and jolts.

In the pages that follow we will examine each unit in turn and find out how it does its job. The engine is the most complicated unit, and several pages are used to describe simply and clearly the various operations and systems that combine to make it work.
