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.
