What are the main parts of a carburetor?

Components of carburetors usually include a storage chamber for liquid fuel, a choke, an idling (or slow-running) jet, a main jet, a venturi-shaped air-flow restriction, and an accelerator pump. The quantity of fuel in the storage chamber is controlled by a valve actuated by a float.

What is on top of a carburetor?

At the top, there’s a valve called the choke that regulates how much air can flow in. If the choke is closed, less air flows down through the pipe and the venturi sucks in more fuel, so the engine gets a fuel-rich mixture.

What are the 7 circuits of a carburetor?

The circuits that comprise a carburetor are broken down into seven categories. They are: float, choke, idle, main metering, power enrichment, accelerator pump, and if applicable, secondary barrels.

What are the types of carburetor?

The carburetor may have plain, double, vane, nozzle-bar and triple venturi. Each type of the venturi is designed to provide the decreased pressure of air flow so that it may draw fuel from the discharge jet. Multiple venturies help to keep the fuel away from the carburetor walls to reduce condensation.

What does the float do in a carburetor?

A float chamber is a device for automatically regulating the supply of a liquid to a system. It is most typically found in the carburettor of an internal combustion engine, where it automatically meters the fuel supply to the engine.

What is the float bowl on a carburetor?

Mounted on the side of the carburetor is the float-feed chamber, or “bowl,” which is essentially a miniature fuel tank fed by the main fuel tank. The carburetor float needle, moved by the float, controls fuel flow, maintaining the fuel level in the chamber.

What are the flaps in a carburetor called?

There are two types of throttle valves: the butterfly, which is a circular disc and the cylindrical which is as large as the inlet pipe and rotates. The throttle is controlled by the accelerator, with cables or rods attached to the throttle by a lever.

What are the five different circuit of the carburetor?

The five most basic circuits in the carburetor are the float, idle, main-metering, power-enrichment, and the accelerator-pump circuits. There are other circuits as well, such as the choke and a vacuum-secondary system, but we’ll concentrate on the most important five.

What metal is carburetor?

The main structure and largest component of the carburetor is the molded body made from a lightweight alloy or aluminum. The stationary body is under little stress and pressure, therefore, stronger metals are unnecessary. The moving pieces of a carburetor are manufactured from steel or stainless steel.
