Purpose and Compatibility

The presented injection system for BMW 3 Series E90, E91 LCI, and E92 has been designed for the 325d and 330d engine units with the N57 engine. The construction is based on factory BMW solutions, which promotes the maintenance of correct engine operating parameters, stable injection pressure, and proper fuel dosing across the entire load range.

The system works with Diesel engines, ensuring precise fuel delivery to the combustion chamber. This allows for maintaining proper engine smoothness, reducing smoke, and ensuring correct engine control system operation.

Technical Characteristics of the Injection System

The set includes components from the injector nozzles category, which are responsible for atomizing diesel fuel under high pressure. The injection technology used allows for:

• precise fuel spray formation in the combustion chamber, which promotes efficient mixture combustion,
• stable engine operation at low and high RPM ranges,
• maintaining adequate vehicle dynamics while limiting fuel consumption,
• compatibility with the factory engine control unit without the need for software modifications.

The injection system in this configuration is particularly important for maintaining proper fuel rail pressure, correct injector opening times, and uniform supply to all cylinders.

Condition, Origin, and Benefits of Use

The offered set comes from the BMW OE line, which means compliance with the manufacturer's factory quality standards. The components are used, making them a cost-effective solution for users looking for an original injection system without the need to invest in new components.

Using a complete injection system to replace faulty or worn-out components allows for:

• restoring proper diesel engine operation for cold and warm starts,
• reducing problems with uneven idling and power drops,
• decreasing the risk of further damage to the engine unit resulting from improper fuel injection.

Diagnostics and Operation of the Diesel Injection System

Before installation, it is recommended to perform computer diagnostics and verify the fuel supply system's operating parameters to confirm that the injection components are the source of the problems. A correctly selected and functional injection system is crucial for the durability of the N57 engine and the safety of vehicle operation.
