A carburetor (also spelled carburettor or carburetter) [1] [2] [3] is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. [4] The primary method of adding fuel to the intake air is through the Venturi tube in the main metering circuit, though various other components are also used to ...
Husqvarna Motorcycles GmbH (Swedish: [ˈhʉ̂ːsˌkvɑːɲa] ⓘ; marketed as Husqvarna) is an Austrian motorcycle company with Swedish origins. The company began producing motorcycles in 1903 at Huskvarna , Sweden, as a subsidiary of the Husqvarna armament firm. [ 1 ]
A pressure carburetor is a type of fuel metering system manufactured by the Bendix Corporation for piston aircraft engines, starting in the 1940s. It is recognized as an early type of throttle-body fuel injection and was developed to prevent fuel starvation during inverted flight .
An updraft carburetor is a type of carburetor in which the air flows upward within the device. [1] Other types are downdraft and sidedraft. [2] An updraft carburetor was the first type in common use. [3] In it air flows upward into the venturi to mix with the fuel. [2] An updraft carburetor may need a drip collector. [4]
Of the three types of carburetors used on large, high-performance aircraft engines manufactured in the United States during World War II, the Bendix-Stromberg pressure carburetor was the one most commonly found. The other two carburetor types were manufactured by Chandler Groves (later Holley Carburetor Company) and Chandler Evans Control ...
Zenith Carburetor (later the Fuel Devices Division of Bendix Corporation) was an American manufacturer of gasoline engine management systems and components, chiefly carburetors and filters. It was founded in Detroit, Michigan in 1911 as a subsidiary of the French Société du carburateur Zénith .
In the conventional carburetor, a venturi in the airflow creates a lowered pressure and this is enough to encourage the flow of fuel through the metering jets. The flow rate is critically sensitive to the fuel pressure at the jet, i.e. the hydrostatic head owing to the depth of fuel between the jet and the float level.
As the whole process is actuated by hydraulic pressure at engine start, there is no need for service or adjustment. Another advantage is cheaper operation, as there is no need for service and charges associated with tappet maintenance. Usually hydraulic tappets survive through the whole of the engine life without any service requirements.
