Understanding Your Car..bureator

Carburetor diagram: Hi there, We're here today to sit down and learn a little bit more about our car. Specifically, the vessel in which air and fuel are blended for intake in an internal combustion engine, a.k.a. your carburetor. Lost already, who wouldn't be after all that? Lets take this a step at a time. The word carburetor itself comes from the french verb carburer, meaning "to mix with carbon". In layman's terms, making fuel more effective in creating combustion. First up to bat, lets look at your carburetor's origins. Karl Benz, the same Karl Benz who founded Mercedes-Benz developed the earliest model of carburetor, the wick carburetor, in 1885. This design was later refined, and went on to complete a 1,000 mile tour at the turn of the century. The structure and shape of a carburetor may sound complicated at first, but its actually very simple. The carburetor is in essence an oddly shaped pipe, called a venturi. The venturi shape assumes that the pipe is thinner in some spots, while wider than others. This design allows the speed of airflow to be controlled, as the thinner spots forces air through at faster speeds. Following so far? Imagine a funnel, go from the rim of the funnel directly across to the opposite side of the funnel. Now move deeper into the funnel and repeat. notice how it was quicker to travel from one side to the next, the further into the funnel you were? Same deal with the venturi pipe concept. Below the pipe is a butterfly valve, which is a disc on a centered pivoting point, that restricts the flow of air. For this, imagine the sign holders whenever you see roadwork. The stop sign is on a pole, and is spun in place on that pole. the sign doesn't move, but its visible portion does. When you see the stop sign, its the same as the valve being shut, when the sign is turned, just like your car, air can flow through. The last part of a carburetor is the fuel valve, which regulates how much fuel is introduced into the flow of air, and later into the combustion cycle of your car. Imagine a classic water gun, squeeze the handle a little, and a little water squirts out. Squeeze it all the way, and you shoot a stream. Hopefully this has helped you come a bit closer to understanding your car as a whole, or at least for now, your carburetor. .
