How Exactly Does a Carburetor Work? – Let’s Discuss

How does a carburetor work? This may be something that you’ve wondered from time to time considering that carburetors aren’t exactly the most common part nowadays. Starting in the 1980’s, the fuel injection system became the more common piece. So if you happen to be one of the lucky ones who still possess this classic part, it’s important you know the facts. So, let’s look into how a carburetor works.

  • From the car’s intake, air will flow through a filter to clean away any debris and into the top of the carburetor.
  • When you start your engine, the choke controls the amount of air that is coming in.
  • By means of a venturi (Wikipedia says that the venturi effect is, “reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a pipe.”) air is forced in which causes it to speed up and for pressure to drop.
  • Suction is then created which draws in fuel.
  • The throttle then controls the air and fuel flow. When this throttle is open, fuel and air flows freely causing more power and speed.
  • Fuel and air goes down into the cylinders and fuel is supplied from the float feed chamber.
  • When that fuel level begins to drop, a float causes a valve to open.
  • Fuel then flows into the main gas tank which causes the float to rise and close the valve.
