Function of the Carburetor Venturi - How it prepares Fuel for Engine Combustion! (by Craig Kirkman)

VISUALLY EXPLAINED The carburetor's venturi, also known as the venturi tube, plays a crucial role in the operation of internal combustion engines. Its function is to control the airflow into the engine by creating a constriction or narrowing in the air passage. Here's how the venturi functions in a carburetor: Airflow Constriction: The venturi is a tube or passage within the carburetor where air flows through. As air enters the carburetor, it encounters the venturi, which is narrower than the surrounding air passages. This narrowing causes an increase in the speed of the airflow. According to Bernoulli's principle, as the velocity of a fluid (in this case, air) increases, its pressure decreases. Pressure Drop: As the air passes through the venturi, its speed increases, resulting in a drop in air pressure. This low-pressure area created by the venturi serves as a vacuum, effectively drawing fuel from the carburetor's fuel bowl or float chamber. Fuel Mixing: The venturi's low-pressure zone is precisely where fuel is introduced into the air stream. Carburetors typically have jets that release fuel into this low-pressure area, allowing it to mix thoroughly with the high-velocity air. This mixture of fuel and air is then carried into the engine's intake manifold for combustion. Efficient Combustion: The venturi's function is vital for creating the right air-fuel mixture. By adjusting the venturi's size and shape, carburetor designers can control the ratio of air to fuel entering the engine. This precise mixture is necessary for efficient combustion and optimal engine performance. In summary, the venturi in a carburetor functions as a flow constriction that increases the speed of incoming air, creating a low-pressure area that draws fuel into the air stream. This process allows the carburetor to provide the engine with the correct air-fuel mixture, ensuring efficient combustion and proper engine operation. I hope you benefit from this video.
