An Eccentric float chamber type carburetor is a type of arrangement according to the float system in the carburetor. A carburetor is the most important component in an engine. The float chamber of the carburetor has a float vassal which indicates the fuel metering in the dashboard. So, the tilting of the vehicle should hamper the metering and measurement of the fuel. In this article, I discuss the eccentric float chamber-type carburetor.
Eccentric float chamber type carburetor–
In an eccentric float chamber-type carburetor, the float chamber is placed at the side of the venturi tube. In an eccentric float chamber type carburetor, the float chamber is placed around the venturi tube.
The eccentric float chamber-type carburetor does not provide the correct air-fuel mixture when the vehicle is ascending or descending a grade. When the vehicle is running on a horizontal road, the level of the gasoline in the float chamber and the discharge jet is normal, as at (A); and the carburetor provides the correct air-fuel mixture to the engine. When the vehicle is ascending or descending a grade, the carburetor is tilted, and the level of the gasoline changes in the discharge jet as at (B) and (C). This causes too much or two little gasoline to be supplied by the jet giving incorrect mixtures.
The concentric float chamber-type carburetor does not have this difficulty. The level of the gasoline in the discharge jet remains approximately constant, which provides the correct air-fuel mixture to the engine in all the positions of the vehicle.
