Carburetor - Other elements

The carburetor (American spelling, carburettor or carburetter in Commonwealth countries, "carb" for short, or "carbie" (slang)) is a device which mixes air and fuel for an internal-combustion engine. Carburetors are still found in small engines and in older or specialized automobiles such as those designed for stock car racing. However, most cars built since the early 1980s use computerized electronic fuel injection instead of carburetion. The majority of motorcycles still are carburated due to lower weight and cost, however as of 2005 many new mod ...

Carburetors are either: Fixed Choke (Venturi) - the varying air pressure in the venturi alters the fuel flow; this is the common downdraft carburetor found on American and most Japanese cars Constant depression - the jet is varied by the air flow to alter the fuel flow; the most common, variable choke (constant depression) type carburetor is the sidedraft SU, which was simple in principle to adjust and maintain. This rose to position of domination in the UK car market for that reason. Other, similar designs are used on some Europea ...

There are persistent rumours which appear to extend into the realm of urban legend or even into conspiracy theory of extremely efficient carburetors. However, there may be some basis for these rumors or claims. One of the basic mechanism is apparently a catalytic carburetor. It would mix fuel fumes with water and air in the presence of heated catalysts such as nickel or platinum. The fuel would break down into methane, alcohols, and other lighter-weight fuels. The lighter-molecular-weight fuels would burn a ...

Too much fuel in the fuel-air mixture is referred to as too "rich"; not enough fuel is too "lean". The "mixture" is normally controlled by adjustable screws on an automotive carburetor, or a pilot-operated lever on a propeller aircraft (since mixture is air density (altitude) dependent). The (stoichiometric) air to petrol ratio is 14.6:1, meaning that for each weight unit of petrol, 14.6 units of air will be burned. In theory this the m ...

Carburetor - Float chamber. To ensure a ready supply of fuel, the carburetor has a "float chamber" (or "bowl") that contains a quantity of fuel ready for use. It converts fuel from fuel pump pressure to atmospheric pressure. This works similarly to a toilet tank; a float controls an inlet valve. If the float drops, the inlet is opened allowing the fuel to flow under the fuel pump's pressure. The level of fuel maintained in the float bowl can usually be adjusted, whether by a setscrew or by something crude such as ...

While low performance carburetors may have only one barrel, most carburetors have more than one venturi, or "barrel", most commonly a two barrel, with 4 barrels being common in higher performance larger displacement engines, to accommodate the higher air flow rate with larger engine displacement. Multi-barrel carburetors can have non-identical primary and secondary barrel{s} of different sizes and calibrated to deliver different air/fuel mixtures; they can be actuated by the linkage or by engine vacuum in "progressive" fashion, so that the s ...

The carburetor was invented by the Hungarian engineer Donát Bánki in 1893. Frederick William Lanchester of Birmingham, England experimented early on with the wick carburetor in cars. In 1896 Frederick and his brother built the first petrol driven car in England, a single cylinder 5 hp (4 kW) internal combustion engine with chain drive. Unhappy with the performance and power, they re-built the engine the next year into a two cylinder horizontally opposed version using his new wick carburetor design. This version completed a 1,000 mile (1600 km) tour in 1900 incorporating successfully the carburetor ...
