Starting fluid is a volatile, flammable liquid which is used to aid the starting of internal combustion engines, especially during cold weather or in engines that are difficult to start using conventional starting procedures. It is typically available in an aerosol spray can, and may sometimes be used for starting direct injected diesel engines ...
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 ...
Quadrajet. The Quadrajet is a four barrel carburetor, made by the Rochester Products Division of General Motors. Its first application was the new-for-1965 Chevy 396ci engine. Its last application was on the 1990 Oldsmobile 307 V8 engine, which was last used in the Cadillac Brougham and full size station wagons made by Chevrolet, Pontiac ...
Vapor lock. Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline -fueled internal combustion engines. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
Flooded engine. A flooded engine is an internal combustion engine that has been fed an excessively rich air-fuel mixture that cannot be ignited. [1] This is caused by the mixture exceeding the upper explosive limit for the particular fuel. An engine in this condition will not start until the excessively rich mixture has been cleared. [2]
Cutaway view of the fuel system for the Ford Model T engine, showing the gravity-feed fuel supply, carburetor cutaway, and intake stream. [4] The Ford Model T engine had one carburetor, a side-draft, single-venturi unit. Its choke and throttle valves were controlled manually; the latter was with a hand lever rather than a foot pedal. The ...
Industrial. In the extraction of petroleum (and other heavy-duty fluid handling contexts), a choke valve (or "choke") is an adjustable flow limiter that is designed to operate at a large pressure drop, at a large flow rate, for a long time. A choke is often a part of the "Christmas tree" at the wellhead . The most familiar choke design is a ...
Dieseling or engine run-on is a condition that can occur in spark-plug -ignited, gasoline -powered internal combustion engines, whereby the engine keeps running for a short period after being turned off, drawing fuel through the carburetor, into the engine and igniting it without a spark. Dieseling is so named because it is similar in effect to ...
