4. Principis de funcionament

These fuel injectors are designed to deliver a precise amount of fuel into the engine's combustion chambers. They are electronically controlled by the vehicle's Engine Control Unit (ECU), which determines the optimal timing and duration of fuel injection based on various engine parameters. The injectors atomize the fuel into a fine mist, ensuring efficient mixing with air for optimal combustion, leading to improved power, acceleration, and fuel efficiency.

5. Manteniment

Fuel injectors are generally designed to be maintenance-free for their operational lifespan. However, their longevity and performance can be affected by fuel quality and engine conditions. To ensure optimal performance:

• Use high-quality fuel from reputable sources.
• Adhere to your vehicle manufacturer's recommended fuel filter replacement schedule. A clogged fuel filter can strain injectors.
• Consider using a high-quality fuel system cleaner periodically, as recommended by your vehicle manufacturer or mechanic, to prevent deposit buildup.
