A carburetor is an important part of any combustion engine. The word carburetor comes from the French word carbide meaning mixing with carbon. It was invented by Karl Benz and has been improved upon over many years. Most cars and other combustion engine vehicles used a carburetor until fuel injection was invented in the late 1980’s. So what is the function of this very important mechanical part? Read this article to find out.
What Does A Carburetor Do?
To understand what a carburetor does it is important to understand how a combustion engine works. Gasoline is burned in the car’s engine to create pressure. This pressure is used to create motion in the car’s engine, which then turns the piston in the engine which is connected to the drive shaft. Hundreds of these tiny explosions are happening within your car engine ever minute.
A carburetors job is to make sure that the right amount of gasoline is mixed with the right amount of air, called the air-to-fuel ratio, to make the engine run smoothly. Too much of either substance causes the engine to splutter and backfire. The carburetor is a tube shaped part and an adjustable plate across the tube called the throttle plate is used to regulate how much air can flow through the tube. In a part of the tube there is a narrow section called the venturi. This creates a vacuum in the tube. The vacuum in the tube allows for the fuel to be sucked up through the jet and for the air being sucked through the carburetor to increase in speed. This pushes the aerated gasoline into the engine where it is combusted by the engine.
