Design of simple carburetor Carburetor is the device that used to mix air and fuel in an internal combustion engine.

The process of preparing a combustible mixture of a certain composition from finely atomized fuel and air that occurs outside the engine cylinders is called carburetion, and the device in which this process occurs is a carburetor. The principle of operation of the simplest carburetor is similar to the principle of operation of the atomizer. Carburetor works this way: liquid under the action of discharge flows from the atomizer, and then mixes with air to form a combustible mixture.

A nozzle is a metal plug with a small calibration hole through which a certain portion of fuel per unit time passes. The simple carburetor consists of a float chamber 8, a diffuser 3, an atomizer 4 with a jet 7, a mixing chamber 6 and a throttle valve 5. In the float chamber there is a hollow float 9 pivotally connected to the axis and acting on the needle valve

Carburetor is a device used for atomizing and vapourizing the fuel and mixing it with the air in varying proportions to suit for changing the operating conditions of engines. The process of breaking up and mixing the fuel with the air is called carburetion. The term vapourization and atomization should be understood clearly. Vaporization is a change of state of the fuel from liquid to vapour whereas atomization is a mechanical breaking-up of the liquid into small particles so that every minute particle of the fuel is surrounded by the air. The carburetor is supposed to supply the fuel air mixture in correct proportion under different conditions of temperature, speed and load on engine. Relatively rich mixture of air fuel ratio of is required by the engine while accelerating or running at high speeds. A leaner mixture of air-fuel ratio of is sufficient while running on levelled roads. For idling, a richer mixture of about I is needed. Similarly, an extremely rich mixture having a ratio of is required during cold starting. Read More :. The main components of a simple carburetor are float chamber, float, nozzle, venturi, throttle valve, inlet valve and metering jet. In the float chamber, a constant level of petrol is maintained by the float and a needle valve. The float chamber is ventilated to atmosphere. It is used to maintain the atmospheric pressure inside the chamber, The float which is normally a metallic hollow cylinder rises and closes the inlet valve as the fuel level in the float chamber increases. The mixing chamber contains venturi, nozzle and throttle valve.

Last updated: August 22, F uel plus air equals motion—that's the basic science behind most of the vehicles that travel on land, over sea, or through the sky. Cars, trucks, and buses turn fuel into power by mixing it with air and burning it in metal cylinders inside their engines. Exactly how much fuel and air an engine needs varies from moment to moment, depending on how long it's been running, how fast you're going, and a variety of other factors. Modern engines use an electronically controlled system called fuel injection to regulate the fuel-air mixture so it's exactly right from the minute you turn the key to the time you switch the engine off again when you reach your destination. But until these clever gadgets were invented, virtually all engines relied on ingenious air-fuel mixing devices called carburetors spelled "carburettor" in some countries and often shortened to just "carb". What are they and how do they work?

Instead, it actuates a mechanism that controls the air flow into the engine.

As the throttle position changes, the composition of the combustible mixture prepared in the carburetor is changing significantly. The throttle valve is regulated by the mechanical linkage cable or pneumatic link to the accelerator pedal of the vehicle. The throttle valve is a butterfly valve that controls the amount of air that can flow through the carburettor. This ensures that there is always enough fuel in the carburettor to supply the engine but not so much fuel that it overflows. Above shown a basic layout diagram of a carburetor, now what I am explaining further you can match it with this diagram to get a proper image of how it works. The speed of air drawn into the cylinder determines the amount of fuel mixed in the air. This results the simple carburetor produce a progressively rich mixture with increasing the throttle opening.

Design of simple carburetor Carburetor is the device that used to mix air and fuel in an internal combustion engine.

The discharge in this chamber depends on the position of the throttle: with the covering of the damper, the consumption decreases, and with the opening increases. The main parts of a simple carburetor are carburetor air filter, float chamber, fuel discharge nozzle, metering orifice , choke valve , throttle valve and venturi. For idling, a richer mixture of about I is needed. Table of Contents Toggle. The goal is to help Steemit grow by supporting Minnows. Our downloads.
