Autolite 2100 Carburetor
Autolite 2100 carburetors were made from 1953 to 1973. They are a synchronous two venturi (barrel) design, meaning both venturii operate together. There are eight different sizes ranging from 190 cfm to 424 cfm. They are available with manual, electric, or automatic hot-air chokes. They incorporate a feature called Annular Fuel Discharge, which greatly reduces the likely-hood of hesitation and flat spots under acceleration. They use the standard Holley bolt pattern (same as Holley two barrels). Size is determined by the diameter of the venturi. This can be found cast into the float chamber side. It will be a number in a circle, with the number being the venturi size in inches. 0.098 - 190 cfm, 1.01 - 240 cfm, 1.02 - 245 cfm, 1.08 - 287 cfm, 1.14 - 300 cfm, 1.21 - 351 cfm, 1.23 - 356 cfm, 1.33 - 424 cfm References {{Reflist Carburettors ...

Venturi Effect
The Venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a pipe. The Venturi effect is named after its discoverer, the 18th century Italian physicist, Giovanni Battista Venturi. Background In inviscid fluid dynamics, an incompressible fluid's velocity must ''increase'' as it passes through a constriction in accord with the principle of mass continuity, while its static pressure must ''decrease'' in accord with the principle of conservation of mechanical energy (Bernoulli's principle). Thus, any gain in kinetic energy a fluid may attain by its increased velocity through a constriction is balanced by a drop in pressure. By measuring pressure, the flow rate can be determined, as in various flow measurement devices such as Venturi meters, Venturi nozzles and orifice plates. Referring to the adjacent diagram, using Bernoulli's equation in the special case of steady, incompressible, inviscid flows (such as t ...

Choke Valve
In internal combustion engines with carburetors, a choke valve or choke modifies the air pressure in the intake manifold, thereby altering the air–fuel ratio entering the engine. Choke valves are generally used in naturally aspirated engines to supply a richer fuel mixture when starting the engine. Most choke valves in engines are butterfly valves mounted upstream of the carburetor jet to produce a higher partial vacuum, which increases the fuel draw. In heavy industrial or fluid engineering contexts, including oil and gas production, a choke valve or choke is a particular design of valve with a solid cylinder placed inside another slotted or perforated cylinder. Carburetor A choke valve is sometimes installed in the carburetor of internal combustion engines. Its purpose is to restrict the flow of air, thereby enriching the fuel-air mixture while starting the engine. Depending on engine design and application, the valve can be activated manually by the operator of the engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat Spot (automobile)
A flat spot, or wheel flat, also called spalling or shelling, is a fault in railroad wheel shape. A flat spot occurs when a rail vehicle's wheelset is dragged along the rail after the wheel/axle has stopped rotating. Flat spots are usually caused by use of the emergency brake, or slip and slide conditions that causes wheels to lock up while the train is still moving. Flat spots are more common in the autumn and winter when the rails are slippery. Flat spots can also be caused by faulty brakes or wheelset bearings. Consequences If the flat spot is very small, the rail vehicle will be able to continue being used. The fault is removed later in the wheelset turning process, using a wheel lathe. However, because of the heat suffered while being dragged along the rail and the impacts suffered afterward, these wheels are more likely to break due to changes in the alloy structure. If the flat spot is very large (as in the picture), strands of molten metal may have stuck on one si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holley Performance Products
Holley Performance Products is an automotive performance company based in Bowling Green, Kentucky. It was founded in 1896 in Bradford, Pennsylvania by George Holley and Earl Holley. When the company was based in Michigan it was a major producer of carburetors for many Detroit-built automobiles. Later they manufactured carburetors for both street and racing applications such as the Holley "Double Pumper" and "Dominator". Holley-style carburetors have powered every NASCAR Sprint Cup team and every NHRA Pro Stock champion until both series eventually switched to electronic fuel injection (EFI). NASCAR Sprint Cup engines still utilize a Holley throttle body and Holley EFI is the spec EFI system in NHRA Pro Stock. Holley's product range has expanded to include the aforementioned fuel injection systems, performance fuel pumps, intake manifolds, superchargers, nitrous oxide injection, performance plumbing parts, exhaust systems, engine dress–up products, ignition products, data- ...
