The unknown is about electronic fuel injection technology

Electronic Fuel Injection or Fuel Injection What is the name of the electronic fuel injection technology?

Electronic fuel injection (Fi)

Electronic fuel injection technology is a concept no stranger to those who are using a motorcycle. The basic principle of Fi is the use of an electronic control system to interfere with the injection of fuel into the engine combustion chamber to optimize fuel use.

The system consists of two main components: sensors and central controls. The sensor continuously monitors the operation of the engine, including the throttle position, intake manifold pressure, intake air temperature, oil temperature, engine speed, and transmits information to the regulator. control.

Highlights of electronic fuel injection technology

We often hear about the application of electronic fuel injection technology to the motorcycle to save fuel. That's just one of the advantages of Fi technology. For us who are using universal motorcycles, we usually only care about Fi in terms of gas savings.

However, for those who love the larger displacement (over 175cc), they usually opt for a large-displacement motor vehicle with Fi technology. Most of these bikes prefer the electronic fuel injection engine because it starts up easily even at low engine temperatures. No need for windscreens and carburetors. All you have to do is rotate the key, then press the start button.

From a structural perspective, the electronic fuel injection system is much more complex, it requires a fuel pump in the compartment, an electronic control unit, and a variety of sensors that control the various functions of the machine. vehicle launch, operation.

Electronic fuel injection is the central electronic control system (ECU) that controls the supply of fuel. The ECU cluster reads the signals of different sensors on the vehicle in turn. Based on the information collected, the ECU determines how much fuel is needed for the optimal operation of the vehicle. ECU is based on the data from the sensor of the rpm, engine temperature, air temperature, crankshaft position, throttle position ... to program the fuel calculation, then open the gas injector .

For us, ordinary users, in addition to saving fuel, Fi technology also helps to protect the environment, reducing the amount of air in the air.
