Carburetors for Oldsmobile

Carburetors have long been considered an essential engine part for many cars. They were especially in use before fuel injected engines became a standard part of a car. Even so, it is good to be familiar with how they work so you can maintain and replace these parts on your Oldsmobile car.

How do carburetors work?

Although the specifics vary depending on the type of carburetor your car has, here is the basic process:

  • Your cars air intake allows airflow into the top of the carburetor after debris is cleaned by the filter.
  • A device called a choke reduces the amount of air that comes in for mixing with fuel when the engine starts up. This ensures that the mixture that enters the cylinders has a higher fuel content.
  • The incoming air goes through something called a Venturi, which is a narrow kink located at the center of the tube. Narrowing the incoming air speeds it up and drops the pressure, which then creates suction within the fuel pipe.
  • A valve called the throttle swivels and opens or closes the pipe. An open throttle allows more fuel and air to be directed to the cylinders, which gives the engine what it needs to produce more power and make the car increase in speed.
  • The fuel mixture flows into the engines cylinders. The fuel comes from a small tank known as the float-feed chamber, which regulates the amount of fuel supplied to the cars engine.
What different types of carburetors are there?

Even though there are a number of different ways to classify the variety of carburetors out there, one of the more common methods is to refer to them by the number of barrels. Barrels are the passageways or containers where fuel and air are mixed. Most carburetors have one, two, or four barrels. One-barrel carburetors are common on smaller engines, and this is because they do not need as much power to function and because larger varieties could be too big to fit the engine. The most common type of carburetor for standard engines is the two-barrel type. However, high-performance vehicle engines often use four-barrel carburetors. For example, race cars often have a four-barrel carburetor. Although only two are in use most of the time, the other two kick in when the cars engine needs more horsepower.
