What happens if a carburetor gets too much air?

What happens if a carburetor gets too much air?

If the carburetor is supplying an air/fuel mixture that is too rich, the engine may tend to load up, foul the spark plugs, run sluggish and lack power. If the fuel pressure drops below the proper pressure, the carburetors air/fuel mixture will go lean and engine damage may follow.

How does fuel flow in a carburetor?

The carburetor has two swiveling valves above and below the venturi. At the top, there’s a valve called the choke that regulates how much air can flow in. If the choke is closed, less air flows down through the pipe and the venturi sucks in more fuel, so the engine gets a fuel-rich mixture.

What is the function of the carburetor?

Carburetor Component s – The function of the carburetor is to mix air and fuel ideally at any RPM. In addition, the carburetor is also used to regulate engine RPM and generate a vacuum inside the intake. The working principle of the carburetor is by using a vacuum or air pressure difference in two spaces.

Where does the air come from in a carburetor?

In this type of carburetor air comes from the top of mixing chamber, and the fuel comes from the bottom of the mixing chamber, here also the same principle works, due to low pressure created by the two venturies fuel comes out through the pipe and then the mixing of fuel and air occurred here.

How does the throttle work on a carburetor?

Beneath the venturi, there’s a second valve called the throttle. The more the throttle is open, the more air flows through the carburetor and the more fuel it drags in from the pipe to the side. With more fuel and air flowing in, the engine releases more energy and makes more power and the car goes faster.

What is the difference between fuel injectors and carburetors?

Carburetor parts are not as expensive as that of fuel injectors. With the use of a carburetor, you get more air and fuel mixture. In terms of a road test, carburetors have more power and precision.
