Simple carburetor. The function of a carburetor is to vaporize the petrol (gasoline) by means of engine suction and to supply the required air and fuel (petrol) mixture to the engine cylinder. As the fuel and air pass ahead of the venturi, the fuel gets vaporized and required uniform mixture is supplied to the engine.

Also, what is the use of carburetor? A carburetor is a device which helps in mixing fuel and air together for facilitating internal combustion inside an internal combustion engine.

How does a carburetor get fuel?

The carburetor has two swiveling valves above and below the venturi. At the top, there's a valve called the choke that regulates how much air can flow in. If the choke is closed, less air flows down through the pipe and the venturi sucks in more fuel, so the engine gets a fuel-rich mixture.

Who invented the carburetor?

Donát Bánki János Csonka George Kingston

What is a butterfly carburetor?

Carburetor, also spelled carburettor, device for supplying a spark-ignition engine with a mixture of fuel and air. The choke, a butterfly valve, reduces the intake of air and allows a fuel-rich charge to be drawn into the cylinders when a cold engine is started.

What does a choke do?

A choke valve is sometimes installed in the carburetor of internal combustion engines. Its purpose is to restrict the flow of air, thereby enriching the fuel-air mixture while starting the engine. Chokes were nearly universal in automobiles until fuel injection began to supplant carburetors.

Why carburetor is not used in diesel engine?

All diesel engine use fuel injection and they always have done. Diesel does not evaporate like petrol does so a carburetor cannot be used and the fuel has to be injected into the intake air under very high pressure in order to get it to atomise. The intake valve(s) close, and the compression stroke begins.
