What is Fuel Injected System in Bikes? Know Complete Details

Indian car manufacturers introduced the Multi-Port Fuel Injection technology back in the 90s. Indian bike brands introduced fuel injection technology in motorcycles in the year 2006.
 

What Exactly is a Fuel Injection System?
 

Fuel injection systems in bikes are similar to the systems used on cars. Hence, they can be defined as follows.

A fuel injection system injects fuel into the combustion zone of an engine using fuel injectors. The process is controlled by the ECU (Engine Control Unit) aboard the bike or car. The introduction of fuel injection technology made carburetors and carburetted engines obsolete.
 

The Simplified Working Principle of a Fuel Injection System
 

A fuel injection system consists of fuel injectors and a fuel pump.

As soon as one twists the throttle of a bike, it activates the pump. The pump then transfers fuel to the injectors. Then, the injectors inject the fuel into the combustion chamber.

The role of the injectors in this system is not only confined to injecting the fuel into the combustion chamber. The injectors also atomize the fuel thus ensuring efficient burning and reduced wastage of fuel.
 

What is the Difference Between a Carburetted Engine and a Fuel-Injected Engine?
 

The primary difference between a carburetted and fuel-injected engine is as follows –

A carburetor relies on the suction generated by the incoming stream of air from the environment. The process is possible due to the presence of a venturi tube. The venturi tube draws the fuel using the vacuum created by the incoming air stream.

A fuel injection system injects atomized fuel through small nozzles of injectors working under high pressure generated from its pump.
 

What are the Many Advantages of a Fuel Injection System?
 

Indian bike brands now mostly sell fuel-injected bikes. This applies to bikes with engines with more than 150 CC of displacement. The sudden shift to fuel injection and partially ditching carburetors is due to the onset of BS 6 emission norms.

Furthermore, the addition of a fuel injection system in bikes comes with many benefits. Some of those benefits are mentioned in the sections below –

  • Fuel-injected bikes in India offer more acceleration in the form of increased throttle response.
  • The fuel-injected engines of bikes can offer linear power and torque delivery across all RPM ranges.
  • Cold starting a fuel-injected bike engine is way easier than a carburetted engine.
  • Carburetted engines lose power at high altitudes. That is not the case with fuel-injected engines. Hence, people who love to take their bikes to hill stations should buy fuel-injected bikes.
  • The engine life of a bike with fuel injection is longer than one with a carburetor.
  • Fuel-injected engines are more fuel-efficient as they eradicated fuel wastage.
  • Fuel-injected engines reduce emissions by many folds.
  • Fuel injection systems can deliver fuel to the engine more efficiently.
  • Frequent tune-ups are not necessary for a fuel-injected engine.
  • Fuel-injected engines can run on high compression ratios thus allowing the engine to deliver impressive torque outputs.
     

What are the Best Fuel-Injected Bikes in India?
 

There are plenty of fuel-injected bikes but the top three are as follows –

  • The Bajaj Pulsar 150. It is a street-style commuter bike. It comes with a sticker price of Rs. 1,19,837* in India.
  • The Bajaj Dominar 400 is a semi-naked street bike. It comes with a sticker price of Rs. 2,63,435* in India.
  • The KTM RC 390 is a fully-faired compact sports bike. It comes with a sticker price of Rs. 3,36,394*.
