A description of the carburetor Venturi

In previous posts I have explained the construction of the carburetor, you can read here first. For now I will explain in more detail about the construction of the carburetor venturi. Venturi is a narrowed area in the carburetor. For more details, you notice the picture below.












In the picture above there are two models of carburetors, carburetor carburetor motorcycle is right and the left image is the carburetor on the car. The two images above have clearly shown a venturi like the blue arrows. But venturi shown by the arrow is a venturi with a fixed or also known as fixed venturi.

However venturi above is just one of the venturi shape of the carburetors. Another addition is a venturi venturi variable. This venturi type carburetor motorcycle in the space formed between the barrel with skepticism / throttle valve. Therefore, in the car carburetor, variable venturi formed by the barrel room with a throttle valve. For clarity consider the picture below!
