Aussi Trend Collection: Carburetor

Automobile lovers who spend their time working towards making the vehicle more efficient and attractive consider the question of choosing between carburetor and EFI very important. Which of these two provides better performance is something they consider before the EFI carburetor replacement. Many people believe carburetor gives better performance but there are many who consider conversion to EFI is better for the automobile in terms of performance. You need to consider how both work and all the pros and cons before making the right decision for your automobile. Both the carburetor and fuel injection systems feed on air and fuel that enter the engine. Performance of each depends on the amount of fuel and air that enters engine cylinders which has pistons and combustion chambers for releasing energy.

Carburetor or Fuel injection system

Electronic Fuel Injection

Carburetors are a sophisticated system that have been in use for long time and started to disappear after 1980s. Carburetors are a metering device that use atmospheric pressure of air and vacuum to provide fuel to the engine. The air fuel ratio of this sophisticated analog machine is based on Bernoulli’s principle. The air flow creates suction in the jet into the venture. Air and fuel mixture is out of the cylinder and engine power is controlled by throttle system in the carburetor systems.

Fuel injection system has wide band oxygen sensor that monitors the fuel mixture at the exhaust. There are separate sensors that monitor throttle position, temperature, air pressure etc. The feedback obtained allows the control unit of Electronic fuel injection system to fine tunes the fuel mixture constantly with changing conditioning. Fuel is sprayed through the throttle body into the intake manifold with throttle body EFI systems. For multi-port systems, each cylinder has its own separate injector with which the fuel is sprayed directly into the intake ports of cylinder head. The multi-port EFI system with sequential injection allows faster and real time air and fuel adjustments.

Advantages of EFI over a mechanical carburetor

If you are considering EFI carburetor replacement, you can consider the advantages of EFI over carburetor for the same. Some of the advantages are:

Carburetor

Low fuel consumption: Carburetors are inefficient during different power conditions as the optimizing air fuel ratio is not possible for all throttle settings. For EFI systems it is possible to achieve lower fuel consumption than carbureted engines. This occurs from the sophisticated electronic control system that monitors and adjusts the air/fuel ratio and thereby maintains optimal combustion conditions.
More power: It is wise to consider EFI carburetor replacement as an electronic fuel injection system in general provides more power and torque. EFI systems are capable of optimizing air and fuel ratio as well as ignition timing over different operating speeds and at the same time tries to maintain optimum performance.
Better reliability: During all the phase of flight, the EFI control units try to maintain the optimum air and fuel ratio. So, they offer better reliability and are far more sustainable than carburetor systems.
Fine staring: One major benefit of EFI system over carburetor is the improved cold and hot staring. It is easy to start with four stroke EFI systems over two stroke engines. The engine has the ability to start at any temperature and at any altitude.
Others: EFI allows effective performance with the use of heavy fuels which are not the case with any small engines. EFI can be used with turbochargers, nitrous oxide and superchargers too.

There are many benefits of electronic fuel injection system over the mechanical carburetor system. These advantages are the reasons you can consider the replacement of carburetor with EFI. Although still many people believe and consider carburetor better for performance for their classic car, upgrading to EFI can be much hotter option to consider.
