I. a) List as many car systems as possible. Compare your list with the rest of the group. Who's got the longest list?

b) What is the fuel system used for?

II. Philip, a student of Automotive Engineering, has met his friend Alex in the laboratory testing. Listen to their dialogue and learn the basic principle of the carburettor operation.

Philip: Hello, Alex! What are you doing?

Alex: Well, I'm studying the fuel system of this car. Now I can tell you a lot about the basic principles of its operation.

Philip: Really? O.K. Let me see. Do you know the name of that little device near the engine?

Alex: Sure, it's called a carburettor.

Philip: And what is it used for?

Alex: Well, it measures out a precise amount of fuel that is mixed with the correct amount of air.

Philip: And do you know the principle of the carburettor operation?

Alex: Oh, that's easy. First, air is drawn down the air intake (it is located directly above the carburettor) into a venturi where its pressure is lowered. That's why, the fuel will flow into the venturi.

Philip; Will it flow because of the low pressure of the air?

Alex: Right you are. Then the air is mixed with the fuel before this mixture is taken into the cylinder combustion chamber.

Philip: Is it really? And what happens with this fuel mixture in the cylinder combustion chamber?

Alex: It is ignited there and is drawn into the engine afterwards.

Philip: I see.
