How Do Carburetors Work? Explained With a Transparent Carburetor

They mix air with fuel, but how and what for?

A carburetor is a device that mixes air and fuel for internal combustion engines. The word comes from the French carbure meaning to combine with carbon.

Today, fuel injection technology had by far replaced carburetors in the automotive and aviation industries but the devices can still be used in small engines such as those for lawnmowers.

In this video, YouTuber SmarterEveryDay seeks to understand exactly how carburetors work. For this lofty goal, he first reaches out to his dad who is busy actually fixing a carburetor for his lawnmower.

After getting a detailed explanation from his father which he does not share with us, the YouTuber proceeds to build a transparent carburetor, so we can see all the inner workings of this small but mighty device.

He explains that a carburetor consists of a top part called the venturi and a bottom part called the bowl. He then proceeds to build both a transparent venturi and a bowl.

He explains in detail what both of these parts do but the really fun part comes when he finally runs gasoline through his transparent carburetor. What happens then? We won't tell you. Watch the video to find out.
