The main difference between a carburetor and a fuel injection system is that a carburetor works at low pressure, since through it the air-gasoline mixture is admitted, while the electronic injection atomizes the fuel through a small high pressure nozzle, (This eliminates much of the cold start problems associated with carburetion).



The injection system evolved and perfected over the years, so there are currently a wide variety of gasoline injections such as: electronic injection, multi-point system or direct injection.


That is why the qualities that we name below are general and refer to fuel injection as such, which replaces the carburetor.

In the first instance, the fuel injection system or fuel injection with respect to the carburetor offers better fuel efficiency and reduction of polluting emissions than a carburetor.


When the system is running, the electronic injection system provides better power, being a much more reliable system to deliver the fuel-air mixture to the engine.


At the beginning of its development, fuel injection was very expensive to maintain, but today it is the primary fuel supply system, used in the vast majority of motorcycles and scooters on the market and gradually replacing carburetors since the beginning of the 1990s. 90, it is currently inexpensive to maintain and easy to maintain.


It should be noted that the fuel injector is only a nozzle and a valve. The power to inject the fuel comes from a pump or pressure vessel located near the fuel supply.


Motorcycle Carburetor Features

The carburetor contains jets that push gases into the combustion chambers. The amount of fuel that can flow from these jets depends entirely on the amount of air that can be drawn into the carburetor.


The main problem with obtaining the best performance using a carburetor is that you cannot control the air-fuel mixture of each cylinder individually, therefore with a carburetor the air-fuel mixture is approximated to achieve the best performance at all times. On the other hand, carburettors, with respect to fuel injection systems, as they do not have electrical components or return lines to the fuel tank, have a much simpler installation and handling.


In addition, the carburetor is currently much more economical than fuel injection systems.


Fuel Injection Features

The systems of fuel injection are increasingly popular for those who want the best performance from your engine. There are two different versions for fuel injection: port and direct injection.


The latter is the most modern and was designed for 2 and 4-stroke motorcycle engines , the main advantages of this system is the amount of fuel and air that can be perfectly released and then injected according to the load conditions of the engine.


The electronics used in this system calculate the information and adjust it at all times. This type of controlled fuel injection results in higher power output, higher fuel efficiency, and much lower emissions.


On the other hand, one of the problems of these injections, which are much more sophisticated and more expensive than a carburetor , the installation is much more complicated due to the diversity of electrical elements and accessories.


Is it better Carburetor or Electronic injection?

It is quite obvious that most motorcycles will switch to fuel injection systems due to the lower emissions. However, unless the cost of these systems drops significantly, there will still be a large following of carburetors .


When it comes to pure horsepower, the fuel injection system only provides an additional 10 horsepower at its peak . It is the ability to constantly adjust the fuel and air intake of each cylinder that benefits performance. Fuel injection systems are the best as they reduce vibration and help overcome steep slopes that are traditional off-roading terrain. Again, which one is the best depends entirely on where and how you are driving.
