Carburetors are mainly of three different types, they are as follows: Up-draft Type Carburetors It is the oldest and the most used type of carburetor. In an updraft carburetor, the air flows upward into the car using the Power Equipment Engine Technology. An updraft carburetor may also require a drip collector Down-Draft Type Carburator In order to achieve high speeds and high power, downdraft carburetors can supply large amounts of fuel. It operates on the same principle as other carburetors, fuel comes out through the pipe and is mixed with air due to low pressure created by the two venturis. Air is fed into this type of carburetor from the top, and fuel is fed from the bottom. Horizontal-Type Carburator Whenever there is a restriction of space for assembly, this type of carburetor is used. Unlike other carburetors, the jet tube of a horizontal carburetor is placed horizontally, as suggested by its name. These carburetors work on the basis of a very straightforward principle. Air is drawn into the carburetor through the one end of the carburetor when the carburetor is horizontal.
