Mikuni carburettor BS 36 SS from a Suzuki motorcycle Mikuni Corporation ( 株式会社ミクニ , Kabushiki gaisha Mikuni ) is a Japanese Automotive products manufacturing company. Their business activities is focused on carburetors, fuel injectors and other automobile and motorcycle related equipment.
Two-barrel downdraft Holley 2280 carburetor Cross-sectional schematic. 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]
Although the needle and jets were still offset, they were moved away from the side of the bore which simplified the needle mounting. Air for the pilot feed was taken from the outside of the carb through a drilling. The GP was available in four body sizes and in flange mounting only: [37] 15GP - 7/8, 15/16", 1" and 11/16" bore diameters
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 .
Needle valves are usually used in flow-metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time, such as the idle fuel flow in a carburettor. Note that the float valve of a carburettor (controlling the fuel level within the carburettor) is not a needle valve, although it is commonly described ...
Carburetor heat (usually abbreviated to 'carb heat') is a system used in automobile and piston-powered light aircraft engines to prevent or clear carburetor icing. It consists of a moveable flap which draws hot air into the engine intake. The air is drawn from the heat stove, a metal plate around the (very hot) exhaust manifold.
Carburetor icing is caused by the temperature drop in the carburetor, as an effect of fuel vaporization, and the temperature drop associated with the pressure drop in the venturi. [2] If the temperature drops below freezing, water vapor will freeze onto the throttle valve, and other internal surfaces of the carburetor. The venturi effect can ...
The Fish carburetor metered its fuel flow through a calibrated tapered groove, connected directly to the accelerator pedal and the throttle butterfly. [1] The fuel metering orifice was controlled in immediate proportion to the throttle position, in a similar manner to the motorcycle slide carburetor .
