Generally, one uses an espresso machine to make espresso. The act of producing a shot of espresso is often termed pulling a shot, originating from lever espresso machines, which require pulling down a handle attached to a spring-loaded piston, forcing hot water through the coffee at high pressure.
A carburetor (American and Canadian spelling), carburator, carburettor, or carburetter (Commonwealth spelling) is a device that blends air and fuel for an internal combustion engine. It is sometimes colloquially shortened to carb in North America or carby in Australia.To carburate or carburet (and thus carburation or carburetion, respectively) is to blend the air and fuel or to equip (an engine) with a carburetor for that purpose.Carburetors have largely been supplanted in the automotive industry by fuel injection. carburetor basically consists of an open pipe through which the air passes into the inlet manifold of the engine. The pipe is in the form of a Venturi: it narrows in section and then widens again, causing the airflow to increase in speed in the narrowest part.
This video explains carburetors and the components involved. They are used to mix the fuel into the air entering the engine, and are placed just before the throttle body.The technology is old, however is still used in small engine applications such as lawnmowers, weedwackers, chainsaws, etc.his video explains carburetors and the components involved.
