Carburetor & Fuel System Parts For Engines

The carburetor is nothing more than one of the mechanical components of the car and automobiles, which works through internal combustion and with controlled ignition. It is located inside the fuel system and takes care of mixing air and fuel, which is then fed into the combustion chamber. The carburetor is the basic element of the entire engine fuel system, in fact, internal combustion.

WHAT IS CARBURETOR

The carburetor does nothing but pulverize the liquid fuel, mixing it with the air. It also allows you to control the power delivered by the engine. The passage of fuel takes place through the gas valve, which is either a butterfly or a gate valve, which are used to regulate the flow of gases. In this way the breathing of the engine itself can be allowed or blocked. The latter is able to aspirate air in an unlimited way when the valve is completely open, but it can become reduced when the valve closes. The carburetor is located in the intake duct, where the speed of the gas increases, while, its pressure is reduced. Here is also the pulverizer, a tube that starts from the area where the petrol is located and is connected to atmospheric pressure.

Through the increase in speed, it allows the passage of fuel that enters through the duct to mix with the air. The injection of petrol is then controlled by a jet that must be below the fuel level and kept constant by a float, which acting on the valve, regulates the flow of gasoline in order to always keep the hydrostatic load constant.

As already indicated, however, some engines operate by injection, whose advantage is that of being able to regulate the pressure and pulverization of the fuel inside the intake ducts. The advantage of injection is the ability to pulverize even when the air velocity in the duct is reduced. The increase in pulverization also reduces the amount of hydrocarbons emitted from the discharge, so there is also greater protection against the environment.

The Carburetor

The carburetor contains jets that will push the gas into the combustion chambers. So with a carburetor, the best fuel to air ratio for each cylinder is approximated for the best performance. However, carburetors do last longer than fuel injection systems and are favored in motor sports.
