Página 82

The maintenance of a vehicle's engine is a complex task that requires technical knowledge and experience. One of the most important components of the engine is the electronic injection system, which is responsible for feeding fuel to the engine. Proper maintenance of this system is crucial to the overall performance of the vehicle.

5.12. Maintenance of a vehicle's engine: Electronic injection system

The electronic injection system is a technology that has replaced the carburetor in many modern vehicles. It controls the amount of fuel that is injected into the engine, optimizing combustion and improving fuel efficiency. However, like any vehicle component, the electronic injection system requires regular maintenance to ensure its proper functioning.

5.12.1. Diagnosis of the Electronic Injection System

The first step in maintaining the electronic injection system is the diagnosis. This involves scanning the system to identify any potential issues. Diagnosis can be performed using a vehicle diagnostic scanner (OBD), which is connected to the vehicle's computer system. The scanner can read the fuel injection system error codes, helping to identify any issues.

5.12.2. Cleaning the Fuel Injectors

Fuel injectors are a crucial part of the electronic injection system. They spray the fuel into the engine's combustion chamber, allowing it to burn efficiently. However, over time, the injectors can become dirty or clogged, which can affect engine efficiency. Regular cleaning of fuel injectors is therefore an important part of electronic injection system maintenance.

5.12.3. Verification and Replacement of Sensors

The electronic injection system uses a series of sensors to monitor various engine conditions, such as temperature, air pressure and the amount of oxygen present in the exhaust gases. These sensors send information to the engine control unit (ECU), which uses this data to adjust the amount of fuel injected into the engine. If these sensors fail or give inaccurate readings, it can affect engine performance. Therefore, checking and regularly replacing the sensors is a crucial part of maintaining the electronic injection system.

5.12.4. Fuel Pump Maintenance

The fuel pump is another key component of the electronic injection system. It pumps fuel from the tank to the fuel injectors. If the fuel pump fails or becomes inefficient, it can affect the amount of fuel that is injected into the engine, affecting the vehicle's performance. Regular fuel pump maintenance, including checking for leaks and replacing worn parts, is essential for maintaining your electronic injection system.

5.12.5. Fuel Filter Replacement

The fuel filter is an important part of the electronic injection system. It removes impurities from the fuel before it is injected into the engine. If the fuel filter is dirty or clogged, it can affect the amount and quality of fuel that is injected into the engine. Therefore, regular fuel filter replacement is a crucial part of electronic injection system maintenance.

In summary, electronic injection system maintenance is a crucial part of overall vehicle engine maintenance. By ensuring this system is working properly, you can improve your vehicle's fuel efficiency, engine performance and longevity.
