Simple carburetor diagram

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 simple carburetor diagram a carburetor. The principle of operation of the simplest carburetor is similar to the principle of operation of the atomizer.

In this post I am going to explain what a simple carburetor is and how it works, not going in deep calculations so a non-technical person can also understand easily. What is carburetor? It is a device which is used in spark ignition engine or you can say petrol engines for proper mixing of air and fuel. As oxygen is needed for combustion so in petrol engine mixing of fuel and air is done through carburettor and then this mixture is sent into the cylinder. 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. A basic carburetor consist of a venturi, a float chamber, a nozzle with metering orifice from float chamber to venture, on the other end of float chamber here is a needle valve to control the fuel supply coming from fuel tank. In suction stroke, when piston moves from top-dead centre to bottom-dead centre a low pressure zone is created inside the cylinder and as the inlet valve opens the air is drawn inside the carburettor and then this air passes through venturi.

A simple carburettor , often called a carb, is a mechanical device that blends air and fuel for an internal combustion engine. This essential component plays a crucial role in the functioning of vehicles, allowing them to efficiently generate power by providing the engine with the optimal air-fuel mixture. Carburettors were commonly used in older vehicles before fuel injection systems became prevalent, and they come in various types, each with its own unique design and characteristics. In this article, we shall be providing a thorough overview of Simple Carburetor and its working. In the later sections, the advantages, disadvantages and applications shall also be covered. A simple carburettor is a device that mixes air and fuel to create a combustible mixture for a gasoline engine. It consists of a float chamber, main fuel jet, venturi, jet tube, and throttle valve. The float chamber contains a float, which helps to maintain a constant level of fuel. Fuel is pumped from the fuel tank to the float chamber through a strainer. The venturi creates a vacuum that draws fuel from the float chamber into the airstream. The jet tube mixes the fuel and air before it enters the engine. The float chamber is a reservoir that maintains a constant fuel level in the carburettor.

Design of simple carburetor Carburetor is the device that used to mix air and fuel in an internal combustion engine. The main objective of the carburetor is to provide quality air-fuel mixture for cruising range and for other special requirements likes at starting, idling, acceleration, variable load, and speed operation condition. Above figure shows a simple carburetor. The main parts of a simple carburetor are carburetor air filter, float chamber, fuel discharge nozzle, metering orifice , choke valve , throttle valve and venturi. The float chamber is vented to the upstream side of the venturi or to the atmosphere. The float goes down as a result of the decreasing amount of fuel inside the chamber. When the fuel level goes down the designed level, the floats go down, actuate the fuel supply valve and admits fuel into the chamber.

Glad you liked it. A simple carburetor has many limitations. Industries using new carburetors available in the market to tackle this situation. No one uses this carburetor nowadays. Table of Contents.

Steem Alliance. When air passes through the venturi the velocity of air increases and the pressure decreases [read venturi meter working principle ]. The density of air also varies with atmospheric pressure.

Nozzle The nozzle is a small hole in the jet tube that allows fuel to flow into the venturi. The Meet the Steemians Contest is over - Results are coming soon We can call this full assembly a simple carburetor. 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 main objective of the carburetor is to provide quality air-fuel mixture for cruising range and for other special requirements likes at starting, idling, acceleration, variable load, and speed operation condition. Closing the throttle valve has the opposite effect, reducing engine power. A simple carburetor is a device that mixes air and fuel in the correct proportion for internal combustion engines.
