Operating Principles

Fuel injectors are precision components that deliver a fine mist of fuel into the engine's combustion chambers. The vehicle's Engine Control Unit (ECU) precisely controls the timing and duration of fuel injection based on various sensor inputs (e.g., engine speed, load, temperature). Once installed correctly, the DUCRES Fuel Injector will operate automatically as part of the vehicle's fuel management system.

Maintenance

Fuel injectors themselves typically do not require routine maintenance. However, maintaining the overall fuel system is crucial for their longevity and performance:

• Fuel Quality: Always use high-quality fuel as recommended by your vehicle manufacturer. Poor quality fuel can lead to deposits and clogging.
• Fuel Filter Replacement: Regularly replace your vehicle's fuel filter according to the manufacturer's schedule to prevent contaminants from reaching the injectors.
• Fuel System Cleaners: Consult with a professional before using fuel system cleaners, as some may not be suitable for all systems.

• Engine misfires or rough idling.
• Reduced fuel efficiency.
• Loss of engine power or acceleration.
• Check Engine Light (CEL) illumination.
• Strong fuel odor.

If any of these symptoms occur, it is imperative to have the vehicle inspected by a professional mechanic immediately. Do not attempt to diagnose or repair complex fuel system issues yourself unless you are a qualified technician.
