Advantages and disadvantages of carburetor

Carburetion is the process of formation of a combustible air-fuel mixture by mixing the proper amount of fuel with air before admission to the engine cylinder. The device with does this job is called a carburettor. Let us have a deep insight into the pros and cons of the carburettor in this article. 

Advantages of carburettor :

  • Carburettor parts are not as expensive as that of fuel injectors, especially EFI, which would give you large savings.
  • With the use of carburettor, you get more air and fuel mixture.
  • In terms of the road test, carburettors have more power and precision.
  • Carburettors are not restricted by the amount of gas pumped from the fuel tank, which means that cylinders can pull more fuel through the carburettor, leading to a denser mixture in the chamber and higher power.

Disadvantages of carburettor :

  • The mixture provided by a carburettor is so weak at very low speed that it will not ignite properly and some arrangement in the carburettor is required for its enrichment under such conditions.
  • The working of the carburettor is affected by changes in atmospheric pressure. 
  • It provides the right mixture at only one engine speed and load, therefore only suitable for engines running at a steady increase or decrease in speed.
  • More fuels are consumed since carburettors are heavier than fuel injectors.
  • More air emissions than fuel injectors.
  • Maintenance costs of the carburettor are higher than with fuel injection system.
