Fuel Injection & Its Advantages – Quick Details

Fuel Injection advantages far outweigh its disadvantages and with Bharat Stage 6 it has become extremely common in motorcycles and scooters…

India has moved to Bharat Stage 6 emission norms from April 2020. This has meant that all motorcycles and scooters have also converted to fuel injection ditching the conventional carburetors.

Fuel Injection is a technology that is used in automobiles and it eliminates the need for carburetors. The technology helps the engine to supply fuel directly to the cylinder in the intake manifold or in simple words it supplies fuel directly to the engine.

What is Fuel Injection?

Fuel injection technology is one wherein fuel is directly supplied to the cylinder in the intake chamber. Sensors located in such engines regulate the flow of fuel injected and maintain it to appropriate levels.

As long as the sensors (usually electronic) are working properly, the possibilities of breakdown and chock are immensely reduced. One can even find different types of fuel injecting systems like throttle body fuel injection systems and single point fuel injection systems.

The throttle body system supplies fuel located on throttle bodies directly to the intake chamber whereas the single point systems supply fuel from a single injector.

Whatever might be the type of fuel injection used, they bring in crispier throttle response and generally a more involving ride. Fuel injection systems also improve fuel efficiency.

How Fuel Injection Works?

Fuel injected engines are efficient when we talk ‘work’. By efficient, I mean the overall engine performance increases. A pump is actually located in the system that makes sure that the fuel efficiently mixes with air and is supplied to the combustion chamber to produce efficient power.

Pump regulates and utilizes the amount of fuel that is subjected to the combustion chamber. Accelerator acts as a command for the pump to start pouring required amount of fuel and air to burn, making the engine generate more power and it results in enhanced throttle response.

Fuel Injection Advantages

Some of the benefits of using Fuel Injected engines are:

  • Throttle response increases, providing the biker appropriate needed power at all rpms.
  • Cold start problems are almost eliminated.
  • Better engine life.
  • It results in Enhanced engine efficiency.
  • It also offers better fuel efficiency.
  • More efficient burning of fuel results in cleaner environment.

Fuel Injection Disadvantages

  • Fuel injectors are costlier than carburetors. That is why you see significant price increments in this BS4 to BS6 transition.
  • The process of isolating and repairing a fuel injector is costlier than carburetors.

It is abundantly clear from the above description that fuel injection technology is the present and future. And with this leap from Bharat Stage 4 to direct Bharat stage 6 emission norms, carburetors are almost dead. Even the cheapest entry level motorcycles and scooters are now offered with fuel injectors.
