Common Rail Injector: Four Tips for Promoting Optimal Performance

The common rail injector is a beneficial component in direct injection auto systems. This unit is designed to deliver fuel from the pump and into injectors at high pressure. This design eliminates the need for holding fuel in the intake manifold. The advantage of this direct injection is improved fuel efficiency and better engine performance. Moreover, there is reduced noise and fewer emissions from the vehicle. If you are on the market for a common rail injector, consider these tips to ensure great performance.

Choose the Right Component

It is important to acquire the right common rail for your fuel injection system. The wrong component can cause a range of problems for your vehicle. For instance, there might be significant loss of power and the fuel efficiency might decline. Also, the engine might deteriorate, and complete failure might occur. Therefore, when making your purchase, you must ensure that the common rail is built according to the original equipment manufacturer standards. This will minimise the probability of malfunction.

Plan for Expert Installation

The installation of a common rail will influence the long-term performance. Poor practices during placement can lead to premature failure of the component and even engine damage. For instance, if a washer or seal ring is missing, there will be leakage of residues which could damage surrounding components. Therefore, it is advisable to plan for installation by a qualified professional to prevent failure and enhance performance.

Prevent Internal Contamination

One of the primary causes of performance decline and malfunction in a direct fuel injection system is contamination. In simple terms, if there is contamination in the vehicle, the common rail will not be able to deliver fuel at the desired pressure. The particles could cause blockages in the equipment, so the injection process will be compromised. Moisture can also pollute the injection system. If water enters the equipment, it will cause erosion of critical parts. Therefore, you must make certain that there is no entry of pollutants into your fuel injection system by promoting proper oil filtration.

Monitor for Malfunctions

Finally, you should monitor the common rail injector for signs of damage. All faults should be repaired immediately to ensure that there is no spread or escalation of the malfunction. The most obvious potential sign of functional decline of the common rail is the engine light. However, there are other signs like leakage of fuel, knocking of the engine, misfiring and more exhaust emissions. If you notice any of these problems, you should plan for prompt professional repairs.
