The float is lifted upward by inertia, closing the fuel inlet valve as if the fuel bowl was full of fuel. Cutting off the fuel supply causes the fuel-air ratio to become greater than sixteen to one, which is then too lean for combustion to take place, stopping the engine. [10] [11] The inverse is also true when the aircraft is in inverted ...
The glass fuel bowl was manufactured by the Lancaster Lens company of Lancaster, Ohio. [14] In 1955 the Wall Street Journal reported: "Bowling Green Manufacturing Co., a subsidiary of Holley Carburetor Co., each year sends its employees dummy "checks" made out for the amount each employee has received indirectly through fringe benefits."
In order to ensure an adequate supply at all times, carburetors include a reservoir of fuel, called a "float chamber" or "float bowl". Fuel is delivered to the float chamber by a fuel pump or by gravity with the fuel tank located higher than the carburetor. A floating inlet valve regulates the fuel entering the float chamber, assuring a ...
Carburetors are provided with a float chamber to provide a constant hydrostatic head of fuel above the carburettor's metering jets, thus a constant pressure. The float chamber itself does not vary the pressure according to demand, but it does vary the supply flowrate with demand, to keep this pressure constant.
The 1992–93 LT1s used speed density fuel management, batch-fire fuel injection and a dedicated Engine Control Module (ECM). In 1994 the LT1 switched to a mass airflow sensor and sequential port injection. A new, more capable computer controlled the transmission as well as the engine and got a new name: Powertrain Control Module (PCM). Where ...
Unlike a carburetor there is no bowl and float assembly. The fuel is fed into the unit via a 3/8in. fuel line and returned to the tank via a 1/4in. line. This continuous flow maintains pressure to the injectors. The fuel passes through a permeable diaphragm, called a pressure regulator, which feeds into the injector mount.
Original design incorporating a leather bellows which was replaced by a piston. This image was published 1908 and 1909 A pair of SU carburettors from an MGB. The SU carburettor is a constant-depression carburettor that was made by a British manufacturer of that name or its licensees in various designs spanning most of the twentieth century.
