Operation of the electronic injection system

Página 13

The electronic injection system is one of the most important components of a modern automobile engine. It is responsible for controlling the amount of fuel that is injected into the engine cylinders, ensuring an efficient and economical operation of the vehicle.

How does the electronic injection system work?

The electronic injection system is made up of several sensors and actuators that send information to the vehicle's electronic center. This information is processed by the central, which determines the amount of fuel that must be injected into the engine.

The most important sensors of the electronic injection system are the air flow sensor, the engine temperature sensor, the throttle position sensor and the oxygen sensor. Each of these sensors sends information about engine conditions to the electronic control unit.

Based on this information, the electronic control unit determines the amount of fuel that must be injected into the engine cylinders. This amount is controlled by an actuator called a fuel injector.

The fuel injector is responsible for spraying the fuel in small drops inside the engine cylinders. The amount of fuel that is injected is controlled by the electronic control unit, which sends an electrical signal to the injector.

In addition, the electronic injection system is also responsible for controlling engine ignition. This is done through a crankshaft position sensor, which sends information about the position of the pistons to the electronic center.

Based on this information, the electronic control unit determines the right time to trigger the spark plugs, ensuring efficient and economical fuel combustion.

What are the advantages of the electronic injection system?

The electronic injection system offers several advantages over the mechanical injection systems used in older vehicles.

First of all, the electronic injection system is capable of precisely controlling the amount of fuel that is injected into the engine. This ensures a more efficient and economical operation of the vehicle, reducing fuel consumption and pollutant emissions.

In addition, the electronic injection system is more reliable and durable than mechanical injection systems. Since there are no moving parts in the electronic injection system, it is less subject to wear and tear and mechanical failures.

Finally, the electronic injection system allows for more precise control of engine ignition. This ensures more efficient combustion and reduces the risk of engine damage caused by detonation.

Conclusion

The electronic injection system is an essential component of a modern automobile engine. It is responsible for controlling the amount of fuel that is injected into the engine cylinders, ensuring an efficient and economical operation of the vehicle.

With the advancement of technology, the electronic injection system has become increasingly sophisticated, offering greater precision and reliability. This ensures smoother, more durable engine operation, reducing maintenance cost and extending vehicle life.
