3. Read and translate the text. Petrol system

The elements are needed for the operation of a motor car engine: electricity and petrol. We have seen how the ignition system works to provide an electric spark at the electrodes of the sparking plugs, and we know that the purpose of the spark is to ignite a mixture of petrol and air in the combustion chambers of the engine. Now we must consider the system that delivers the petrol to be ignited.

In cars of normal design, the petrol system consists of three main units: a storage tank, a pump and a carburetor. The petrol tank is fitted at the back of the car where it is out of the way, yet easily filled at a garage. Tanks vary in capacity but they usually hold enough petrol for 250 -300 miles running. Because the tank is at the opposite end of the car from the carburetor, which is fitted high up on the engine, a pump is needed to draw the petrol from one to other, as it is from the carburetor that the petrol is finally fed into the engine.

Pumps can be of two kinds: electrically operated or mechanically driven from the engine.
